Mitigating Concentration Risk in Large Portfolios
Discover how to mitigate concentration risk in your portfolio with diversification, hedging, and tax-aware strategies from Ron McCoy.
For high-net-worth investors, portfolio concentration—owning a significant portion of wealth in one or a few positions—can be a silent risk that erodes wealth during market downturns. Precision investment planning requires addressing concentration risk head-on to safeguard long-term growth and stability.
Ron McCoy emphasizes that true financial strength comes from strategic diversification and proactive risk mitigation, not just riding on a handful of winners.
What Is Concentration Risk?
Concentration risk arises when a portfolio’s performance becomes overly dependent on one asset, sector, or market. While large positions can generate significant gains, they expose investors to outsized losses if that asset falters.

Why It Matters
Studies have shown that portfolios with more than 25% exposure to a single asset are at elevated risk of volatility and drawdowns. Morningstar data suggests that diversified portfolios outperform concentrated ones over a full market cycle, with lower volatility and greater risk-adjusted returns.
Case Study: The Tech Bubble Bust
A 2001 tech entrepreneur held 80% of his net worth in a single high-flying NASDAQ stock. When the dot-com bubble burst, the stock plummeted 85%, slashing his net worth from $10M to under $2M in a year. Diversification across sectors could have preserved much of his capital.
Core Strategies to Mitigate Concentration Risk
Ron McCoy’s precision planning leverages the following approaches:
1. Strategic Diversification
Spread holdings across sectors, asset classes, and geographies to avoid single-point failures. Aim for no more than 15% exposure to any one asset.
2. Hedging with Options
Use protective puts or collars to limit downside risk on large single-stock positions while retaining some upside potential.
3. Gradual Rebalancing
Implement a tax-efficient divestment plan, selling down concentrated positions over time to minimize tax impact and redeploy capital into diversified holdings.
Actionable Tips for Investors
- Run Regular Stress Tests: Use tools like Morningstar’s Portfolio X-Ray to identify hidden concentration risks.
- Tax-Aware Diversification: Coordinate with your advisor to time sales around capital gains tax thresholds.
- Stay Vigilant: Reassess portfolio exposure annually, especially after major market moves or windfalls.
