Building a resilient business portfolio isn’t about chasing the hottest investment trend or putting all your capital into a single promising venture. It’s about creating a strategic safety net that protects your business assets while positioning you for sustained growth across different market conditions.
The financial landscape is constantly shifting. Economic downturns, industry disruptions, regulatory changes, and global events can dramatically impact your business investments. That’s why diversification remains the cornerstone of intelligent portfolio management—it’s the proven method for reducing risk without sacrificing growth potential.
In this comprehensive guide, you’ll discover actionable diversification strategies tailored specifically for business owners and investors. Whether you’re managing a small business investment portfolio or overseeing substantial corporate assets, these time-tested principles will help you build financial resilience that lasts.
Understanding Portfolio Diversification: More Than Just Spreading Your Bets
Portfolio diversification is the strategic practice of distributing investments across different asset classes, industries, and geographic regions to minimize risk exposure. Think of it as building a championship sports team—you wouldn’t field an entire roster of quarterbacks. You need defensive players, offensive linemen, and special teams working together to win consistently.
The fundamental principle behind diversification is simple: different investments respond differently to market conditions. When technology stocks surge, international bonds might remain stable. During economic uncertainty, precious metals often gain value while equities decline. By holding a variety of assets, you create natural hedges that protect your portfolio from catastrophic losses.
The Real Cost of Concentration Risk
Holding concentrated positions—where a single investment represents more than 10% to 20% of your total portfolio—exposes you to significant idiosyncratic risk. This technical term describes vulnerability to problems specific to one company or sector, completely independent of broader market performance.
Consider this sobering statistic: In a recent year when the S&P 500 gained over 25%, nearly 70% of individual stocks within that index still experienced drawdowns of at least 15%. This data reveals a critical truth—a rising tide doesn’t lift all boats. Even in banner years, individual investments can suffer devastating losses due to earnings disappointments, regulatory issues, or management failures.
For small business owners, this risk becomes even more pronounced. Many entrepreneurs have the majority of their wealth tied up in their operating business. Adding concentrated investment positions on top of that creates a dangerous double-exposure scenario where both your business and investment portfolios could decline simultaneously.
Core Pillars of Effective Portfolio Diversification

Building a truly diversified portfolio requires understanding and implementing multiple layers of risk management. These foundational pillars work together to create resilience across different market environments.
Asset Class Diversification: Your First Line of Defense
Asset class diversification involves spreading investments across fundamentally different investment categories. Each asset class behaves differently during various economic cycles, providing natural balance to your portfolio.
The Major Asset Classes:
- Equities (Stocks): Offer high growth potential but come with significant volatility. Ideal for long-term wealth accumulation.
- Fixed Income (Bonds): Provide stability and regular income streams. Government bonds typically hold value during stock market downturns.
- Real Estate: Combines appreciation potential with rental income. Often moves independently from stock market cycles.
- Cash Equivalents: Money market funds and short-term instruments offer liquidity and preservation of capital.
- Commodities: Raw materials like gold, oil, and agricultural products hedge against inflation and currency fluctuations.
- Alternative Investments: Private equity, venture capital, and hedge funds provide access to non-traditional return sources.
Geographic Diversification: Thinking Beyond Borders
Geographic diversification protects against country-specific economic problems, political instability, and currency risks. International investments allow you to capture growth in economies that may be thriving while your home market struggles.
Developed Markets (Japan, Germany, UK, France) offer stability through mature economies, established regulatory frameworks, and predictable legal systems. These markets provide steady, reliable returns with lower volatility.
Emerging Markets (India, Brazil, Vietnam, Indonesia) present higher growth potential alongside increased risk. These rapidly developing economies offer exposure to expanding middle classes and industrial modernization.
Research from Harvard Business School covering the period from 1986 to 2016 demonstrates that despite increasing global market correlation, geographic diversification continues to provide significant risk reduction benefits for long-term investors. Different economies still respond uniquely to global events, creating valuable diversification opportunities.
Sector and Industry Diversification
Even within equity investments, spreading across different economic sectors prevents over-concentration in any single industry. A well-balanced approach includes exposure to:
- Technology and telecommunications
- Healthcare and pharmaceuticals
- Consumer staples and discretionary spending
- Financial services and banking
- Industrial manufacturing
- Energy and utilities
- Real estate and construction
The technology sector might represent 35% of the S&P 500’s total weight through just 10 companies. Without deliberate sector diversification, you risk accidental concentration in a few dominant players.
Investment Style Diversification
Balancing different investment approaches creates additional stability:
- Growth vs. Value: Growth stocks offer rapid expansion potential; value stocks provide steady dividends and trading below intrinsic worth.
- Large-Cap vs. Small-Cap: Large corporations deliver stability; smaller companies often provide greater growth opportunities despite higher volatility.
- Active vs. Passive: Actively managed funds seek to outperform benchmarks; passive index funds offer low-cost market exposure.
The Diversification Strategy Framework for Business Portfolios
| Diversification Layer | Purpose | Recommended Allocation Range | Rebalancing Frequency |
|---|---|---|---|
| Asset Class Mix | Spread risk across different investment types | 60-80% equities, 20-40% fixed income for moderate investors | Quarterly or Semi-annually |
| Geographic Allocation | Capture global growth opportunities | 20-40% international exposure | Annually |
| Sector Distribution | Avoid industry-specific downturns | Maximum 20% in any single sector | Semi-annually |
| Alternative Investments | Access non-correlated returns | 5-15% of total portfolio | Annually |
| Cash Reserves | Maintain liquidity for opportunities | 5-10% for operational flexibility | Monthly review |
Building Your Personalized Diversification Strategy
Creating an effective diversification plan requires honest self-assessment and clear objective-setting. Your strategy should reflect your unique business circumstances, financial goals, and risk tolerance.
Step 1: Define Your Investment Timeline and Objectives
Your investment horizon dramatically influences appropriate diversification strategies:
- Short-term goals (1-3 years): Focus on capital preservation through bonds, money market funds, and high-quality dividend stocks.
- Medium-term goals (3-10 years): Balance growth and stability with a 60/40 stock-to-bond allocation.
- Long-term goals (10+ years): Emphasize growth through higher equity allocation (70-90%) with strategic alternative investments.
Business owners often juggle multiple objectives simultaneously: funding operations, building retirement security, succession planning, and wealth preservation. Each goal may require a separate portfolio with distinct diversification characteristics.
Step 2: Assess Your True Risk Tolerance
Understanding your risk tolerance goes beyond simple questionnaires. It requires confronting uncomfortable questions:
How would you genuinely react if your portfolio declined 20% in a single month?
- Conservative Investors: Prioritize capital preservation above all else. Portfolio composition: 30-40% equities, 50-60% bonds, 10% cash and alternatives.
- Moderate Investors: Seek balanced growth and preservation. Portfolio composition: 60% equities, 35% bonds, 5% alternatives and cash.
- Aggressive Investors: Target maximum long-term growth. Portfolio composition: 80-90% equities, 5-10% bonds, 5-10% alternatives.
Your risk tolerance isn’t static—it evolves with age, business performance, family circumstances, and market conditions. Regular reassessment ensures your portfolio remains aligned with your current situation.
Step 3: Construct Your Core Asset Allocation
Asset allocation—determining what percentage of your portfolio goes to each investment category—is the single most important decision affecting long-term returns. Studies show that over 90% of portfolio performance variability comes from asset allocation decisions rather than individual security selection.
Sample Core Allocation for a Moderate Business Owner:
- 40% U.S. Large-Cap Stocks
- 15% U.S. Small/Mid-Cap Stocks
- 10% International Developed Markets
- 10% Emerging Markets
- 20% Investment-Grade Bonds
- 5% Real Estate Investment Trusts (REITs)
This foundation provides broad market exposure while maintaining diversification across multiple dimensions.
Essential Investment Vehicles for Portfolio Diversification

| Investment Vehicle | Best For | Advantages | Considerations |
|---|---|---|---|
| Exchange-Traded Funds (ETFs) | Broad market exposure with low costs | High liquidity, tax efficiency, instant diversification | Requires brokerage account, trading commissions |
| Mutual Funds | Hands-off professional management | Professional oversight, automatic rebalancing | Higher expense ratios, potential tax inefficiency |
| Individual Stocks | Hands-on investors seeking control | Complete control over holdings, no management fees | Requires significant research, time commitment |
| Real Estate Investment Trusts (REITs) | Income generation and property exposure | Dividend income, real estate without property management | Interest rate sensitivity, sector concentration |
| Treasury Bonds | Maximum safety and stability | Government backing, predictable returns | Lower yields, inflation risk |
| Corporate Bonds | Higher income than government bonds | Better yields than Treasuries, diverse issuers | Credit risk, less liquidity than stocks |
Advanced Diversification Strategies for Business Portfolios
Strategy 1: Alternative Investments for Enhanced Returns
Alternative investments provide access to returns that don’t move in lockstep with traditional stock and bond markets. This low correlation creates powerful diversification benefits.
Real Estate Investments:
Direct property ownership offers tangible assets that generate rental income and appreciate over time. However, it requires significant capital, ongoing management, and lacks liquidity.
Real Estate Investment Trusts (REITs) solve these problems by offering stock-like liquidity while providing exposure to commercial properties, apartment complexes, and specialized real estate sectors. REITs must distribute 90% of taxable income as dividends, creating reliable income streams.
Commodities and Precious Metals:
Gold has served as a safe-haven asset for thousands of years, typically gaining value during economic uncertainty and high inflation periods. A modest 5-10% allocation to precious metals provides portfolio insurance against catastrophic market events.
Other commodities—oil, natural gas, agricultural products—offer additional diversification and inflation protection. These can be accessed through commodity ETFs, futures contracts, or stocks of commodity-producing companies.
Private Equity and Venture Capital:
For accredited investors with high risk tolerance, private equity provides access to non-public companies with potentially explosive growth. Private equity investments typically require capital lockups of 7-10 years but may deliver returns exceeding 20% annually for successful funds.
Strategy 2: International and Emerging Market Exposure
Despite increasing global interconnection, international diversification remains highly effective. Different countries experience unique economic cycles, political environments, and demographic trends.
Implementing Global Diversification:
- Developed International (20-25% of equities): Provides exposure to mature economies with established corporations. Consider funds tracking the MSCI EAFE Index covering Europe, Australasia, and Far East.
- Emerging Markets (10-15% of equities): Captures growth in rapidly developing nations. These markets often have lower correlations to U.S. stocks despite higher volatility.
Currency Considerations:
International investments introduce currency risk—the potential for exchange rate fluctuations to impact returns. While this adds volatility, it also provides diversification benefits when the dollar weakens.
Strategy 3: Fixed Income Ladder Strategy
Rather than holding bonds with identical maturity dates, create a “ladder” with bonds maturing at regular intervals (every 1-2 years over a 10-year period). This strategy:
- Provides regular cash flow for reinvestment
- Reduces interest rate risk by spreading maturities
- Allows you to capture higher rates as they become available
- Maintains liquidity through regular maturity events
Strategy 4: Tax-Efficient Location Strategy
Where you hold specific investments significantly impacts after-tax returns:
Tax-Advantaged Accounts (401(k), IRA, SEP-IRA):
- Hold tax-inefficient investments: bonds generating regular interest, REITs, actively managed funds with high turnover
Taxable Brokerage Accounts:
- Hold tax-efficient investments: growth stocks held long-term, low-turnover index funds, municipal bonds
This strategic placement can add 0.5-1.0% to annual returns through tax savings alone.
Rebalancing: The Disciplined Art of Portfolio Maintenance

Portfolio drift occurs naturally as different assets grow at varying rates. Your carefully crafted 60/40 allocation might become 70/30 after a strong stock market run, significantly increasing your risk exposure beyond intended levels.
Time-Based Rebalancing
Review and adjust your portfolio on a predetermined schedule:
- Quarterly: For larger portfolios or during volatile markets
- Semi-Annually: The sweet spot for most business portfolios
- Annually: Minimum frequency for long-term investors
Threshold-Based Rebalancing
Rebalance only when an asset class deviates from its target by a specific percentage:
- 5% threshold: More frequent rebalancing, higher transaction costs, tighter control
- 10% threshold: Less frequent trading, lower costs, looser control
Example Scenario:
Your target allocation is 60% stocks, 40% bonds. After a stellar year for equities, your actual allocation shifts to 68% stocks, 32% bonds. You would sell 8% of your stock holdings and purchase bonds to restore the 60/40 balance.
This disciplined approach forces you to “sell high and buy low”—taking profits from outperformers and adding to undervalued positions—without emotional decision-making.
Tax-Efficient Rebalancing Techniques
- Use New Contributions: Direct fresh capital to underweight positions rather than selling overweight holdings.
- Rebalance in Tax-Advantaged Accounts: Execute rebalancing trades in IRAs and 401(k)s to avoid capital gains taxes.
- Harvest Tax Losses: Sell positions with losses in taxable accounts to offset capital gains while maintaining overall allocation.
- Consider Qualified Dividends: Time rebalancing to occur after receiving preferential tax treatment on qualified dividends.
Diversification Strategies by Business Type and Size
| Business Type | Primary Focus | Recommended Strategy | Key Considerations |
|---|---|---|---|
| Startup/Early-Stage | Capital preservation during growth phase | Conservative approach: 50% bonds, 30% large-cap stocks, 20% cash | Maintain high liquidity for operational needs |
| Established Small Business | Balanced growth and stability | Moderate approach: 60% equities (diversified), 30% bonds, 10% real estate | Consider business lifecycle and succession planning |
| Medium Business | Growth with managed risk | Moderately aggressive: 70% equities (including international), 20% bonds, 10% alternatives | Separate business reserves from investment capital |
| Large Corporation | Sophisticated multi-strategy approach | Custom allocation: 60% global equities, 25% fixed income, 15% alternatives and hedge strategies | Professional management, institutional quality investments |
| Family-Owned Business | Multi-generational wealth preservation | Conservative-moderate: 55% equities, 35% bonds, 10% real estate and alternatives | Estate planning integration, tax efficiency priority |
Common Diversification Mistakes to Avoid
Mistake #1: False Diversification
Holding 10 different mutual funds sounds diversified until you discover they all invest in the same large-cap U.S. stocks. This overlapping creates the illusion of diversification while maintaining concentrated risk.
Solution: Analyze underlying holdings to ensure true asset class and sector diversification.
Mistake #2: Over-Diversification (“Diworsification”)
Spreading investments across 50+ individual stocks or 15+ mutual funds creates management complexity without additional risk reduction. Beyond 20-30 carefully selected positions, additional diversification adds minimal benefit.
Solution: Focus on quality over quantity. A portfolio of 20-30 strategically chosen investments provides sufficient diversification.
Mistake #3: Set-It-and-Forget-It Mentality
Market movements naturally alter your allocation over time. Failing to rebalance allows risk levels to drift significantly from your original plan.
Solution: Implement systematic rebalancing at predetermined intervals or thresholds.
Mistake #4: Emotional Rebalancing
Panic-selling during market downturns or chasing hot trends destroys the benefits of systematic rebalancing.
Solution: Stick to your predetermined rebalancing schedule regardless of market conditions.
Mistake #5: Ignoring Costs and Taxes
Investment fees and tax inefficiency can consume 1-2% of annual returns—enough to dramatically impact long-term wealth accumulation.
Solution: Prioritize low-cost index funds, ETFs, and tax-efficient investment placement strategies.

Real-World Case Study: Diversification in Action
Background: Sarah owns a successful marketing consultancy generating $500,000 in annual revenue. She had accumulated $750,000 in investment savings, with 65% held in technology stocks due to familiarity with the sector. Her business also operates exclusively in the technology industry.
Problem: Sarah faced dangerous concentration risk—both her business income and investment portfolio depended on technology sector performance. A major tech downturn could simultaneously impact her business revenue and investment portfolio value.
Diversification Solution Implemented:
Phase 1 (Months 1-6):
- Gradually reduced technology stock holdings from 65% to 20%
- Used systematic monthly sales to minimize capital gains taxes
- Harvested $15,000 in tax losses from underperforming tech positions
Phase 2 (Months 7-12):
- Established diversified core allocation:
- 25% U.S. Large-Cap (Multi-sector)
- 15% U.S. Small/Mid-Cap
- 20% International Developed Markets
- 10% Emerging Markets
- 20% Investment-Grade Bonds
- 10% REITs and Alternative Investments
- Moved bond holdings to tax-advantaged IRA
- Placed growth stocks in taxable account for long-term capital gains treatment
Results After 3 Years:
- Portfolio volatility decreased by 32%
- Maintained comparable returns to previous concentrated position
- Survived 18% technology sector correction with only 8% total portfolio decline
- Generated $21,000 in annual REIT dividend income
- Achieved better risk-adjusted returns (Sharpe ratio improved from 0.65 to 0.89)
Key Lessons:
- Diversification doesn’t necessarily reduce returns—it reduces risk for given return levels
- Tax-efficient transition planning preserved $18,000 in taxes over 18 months
- Geographic diversification captured growth in recovering international markets
- Peace of mind from reduced concentration allowed Sarah to focus on business growth
Measuring Diversification Effectiveness

Key Metrics to Track
1. Correlation Coefficient: Measures how closely different investments move together. Perfect correlation = 1.0; perfect negative correlation = -1.0. Effective diversification targets low or negative correlations between major holdings.
2. Standard Deviation: Quantifies portfolio volatility. Lower standard deviation indicates smoother, less volatile returns. Compare your portfolio’s standard deviation to appropriate benchmarks.
3. Sharpe Ratio: Measures risk-adjusted returns by comparing portfolio returns to risk-free rates relative to volatility. Higher Sharpe ratios (>1.0) indicate better risk-adjusted performance.
4. Maximum Drawdown: Identifies the largest peak-to-trough decline your portfolio has experienced. This metric reveals your portfolio’s worst-case scenario during market stress.
5. Beta: Compares your portfolio’s volatility to a benchmark index. Beta of 1.0 moves with the market; <1.0 indicates lower volatility; >1.0 suggests higher volatility.
Benchmark Comparison Framework
| Portfolio Type | Appropriate Benchmark | Expected Annual Return Range | Expected Maximum Drawdown |
|---|---|---|---|
| Conservative | 30/70 Stock/Bond Mix | 4-6% | -10% to -15% |
| Moderate | 60/40 Stock/Bond Mix | 6-8% | -15% to -25% |
| Aggressive | 80/20 Stock/Bond Mix | 8-10% | -25% to -35% |
| Very Aggressive | 90/10 Stock/Bond Mix | 9-12% | -30% to -40% |

The Role of Professional Guidance in Diversification

While many investors successfully implement diversification strategies independently, professional guidance offers significant advantages:
When to Consider Professional Help
Complexity Indicators:
- Portfolio exceeds $500,000 in investable assets
- Managing multiple account types (taxable, IRA, 401(k), trust accounts)
- Transitioning concentrated business positions
- Navigating complex tax situations
- Approaching retirement with income planning needs
- Managing inherited assets or sudden wealth events
Types of Professional Advisors
Certified Financial Planner (CFP®): Provides comprehensive financial planning including investment management, retirement planning, tax strategies, and estate planning. Fiduciary duty to act in your best interest.
Chartered Financial Analyst (CFA): Specializes in investment analysis, portfolio management, and security selection. Ideal for sophisticated investment strategy implementation.
Certified Public Accountant (CPA): Focuses on tax-efficient investment strategies, cost-basis tracking, and coordination between investment planning and tax planning.
Fee-Only vs. Commission-Based: Fee-only advisors charge transparent hourly rates or percentage-based fees without product sales commissions, eliminating conflicts of interest. Expect 0.5-1.5% of assets under management annually.
Emerging Trends in Portfolio Diversification
Environmental, Social, and Governance (ESG) Integration
ESG investing incorporates sustainability factors into investment decisions without necessarily sacrificing returns. Studies show ESG-focused portfolios may actually reduce risk by avoiding companies with poor governance or environmental practices.
Implementation Approaches:
- Negative Screening: Exclude specific industries (tobacco, weapons, fossil fuels)
- Positive Screening: Target companies with strong ESG practices
- Impact Investing: Direct capital to companies solving specific social/environmental problems
- ESG Integration: Incorporate ESG factors alongside traditional financial analysis
Thematic Investing
Rather than traditional sector classification, thematic strategies target long-term structural trends:
- Clean energy and climate change solutions
- Aging population and healthcare innovation
- Artificial intelligence and automation
- Cybersecurity and data privacy
- Water scarcity solutions
Caution: Thematic investments can become crowded and overvalued. Limit thematic allocations to 5-10% of total portfolio.
Cryptocurrency and Digital Assets
While highly speculative and volatile, cryptocurrencies have emerged as a potential portfolio diversification tool due to low correlation with traditional assets.
Conservative Approach:
- Limit allocation to 1-5% maximum
- Focus on established cryptocurrencies (Bitcoin, Ethereum)
- Use only capital you can afford to lose completely
- Recognize regulatory uncertainty and security risks
Factor-Based Investing
Academic research identifies specific characteristics (factors) that drive returns:
- Value: Stocks trading below intrinsic value
- Momentum: Recent outperformers continuing strong performance
- Quality: Companies with strong balance sheets and stable earnings
- Low Volatility: Stocks with below-average price fluctuations
- Size: Small-cap companies historically outperforming large-caps
Factor-based portfolios can enhance diversification by targeting specific return drivers rather than traditional asset classes.
Frequently Asked Questions About Portfolio Diversification
Q: How many individual stocks do I need to be properly diversified?
A: Research suggests 20-30 carefully selected stocks from different sectors provide most diversification benefits. Beyond 30-40 holdings, additional risk reduction becomes minimal while management complexity increases significantly. For most investors, broad-market ETFs offering instant diversification across hundreds of companies present a more practical solution.
Q: Does diversification guarantee I won’t lose money?
A: No. Diversification reduces unsystematic risk (company-specific problems) but cannot eliminate systematic risk (broad market declines). During severe market crashes like 2008, virtually all asset classes declined simultaneously, though diversified portfolios generally fell less than concentrated ones. Organizations like DAF Hold Co illustrate how broadening investment portfolios across multiple assets reduces volatility. Diversification aims to improve risk-adjusted returns over long periods, not prevent all losses.
Q: How often should I rebalance my portfolio?
A: Most long-term investors benefit from rebalancing once or twice annually, or when allocations drift 5-10% from targets. More frequent rebalancing generates higher transaction costs and potential tax liabilities without meaningful risk reduction. Avoid checking your portfolio daily—constant monitoring encourages emotional reactions to market noise.
Q: Should I diversify internationally given U.S. market strength?
A: Absolutely. While U.S. markets have dominated recently, this won’t continue indefinitely. The 2000s saw international stocks significantly outperform U.S. equities. Geographic diversification provides exposure to 95% of global market capitalization outside the United States, access to faster-growing emerging economies, and currency diversification benefits. Target 20-40% international allocation for optimal diversification.
Q: Are bonds still necessary in a diversified portfolio with low yields?
A: Yes, though their role has evolved. Despite lower yields compared to historical averages, high-quality bonds still provide crucial stability during stock market turmoil. During the March 2020 COVID crash, investment-grade bonds held steady while stocks plummeted 30-35%. Consider inflation-protected securities (TIPS), short-duration bonds, and strategic bond ladders to enhance fixed income effectiveness in low-rate environments.
Q: Can I diversify within my 401(k) plan options?
A: Most 401(k) plans offer sufficient diversification through target-date funds or a combination of stock and bond index funds. Focus on selecting funds that cover different asset classes: U.S. large-cap, small-cap, international, and bonds. Avoid company stock concentration—never hold more than 10% in employer securities. Supplement 401(k) diversification through IRA and taxable accounts if needed.
Building Long-Term Resilience Through Strategic Diversification
Portfolio diversification isn’t a one-time project or a set-and-forget strategy. It’s an ongoing discipline that requires regular attention, periodic adjustment, and unwavering commitment to your long-term financial objectives.
The business owners and investors who weather economic storms most successfully share common characteristics: they diversify broadly across multiple dimensions, rebalance systematically regardless of market conditions, maintain discipline during both boom and bust cycles, and focus on long-term objectives rather than short-term market movements.
Your diversified portfolio should reflect your unique circumstances—your business type, investment timeline, risk tolerance, tax situation, and financial goals. What works for a 30-year-old startup founder differs dramatically from the strategy appropriate for a 55-year-old business owner preparing for succession.
Remember these fundamental principles:
✅ Diversification reduces risk without necessarily sacrificing returns
✅ Asset allocation drives 90%+ of portfolio performance variability
✅ Geographic diversification remains effective despite globalization
✅ Systematic rebalancing forces disciplined “buy low, sell high” behavior
✅ Tax-efficient implementation can add 0.5-1.5% to annual returns
✅ Professional guidance becomes increasingly valuable as complexity increases
The financial markets will continue experiencing volatility, economic cycles will persist, and unexpected events will periodically shock global systems. What separates successful investors from everyone else isn’t the ability to predict these events—it’s having a resilient, properly diversified portfolio positioned to survive the inevitable storms and capture the opportunities that follow.
