Concentrated Positions: The Elephant In The Room 

Market Volatility Presents Opportunity to Address a Major Portfolio Risk, In Our View


  • We believe concentrated positions can make portfolios more susceptible to “lightning strikes”.
  • Concentrated positions in the stock of one’s employer can be especially dangerous, in our view.
  • The more a concentrated position underperforms, the more difficult it becomes to execute a well-devised investment plan, in our view.

In our opinion, concentrated positions present one of the biggest obstacles standing in the way of an investor achieving their long-term investment goals. The most sophisticated financial planning tools and the most capable portfolio management teams cannot insulate an investor from the risks presented by these positions. While many investors would prefer to address a concentrated position ‘tomorrow’ when share prices are higher or their tax status is more favorable, it is important to recognize that time is not always on the investor’s side. In this day of 24-hour news, the fortunes of any company can change rapidly without warning alarms. We have seen too many investors losing too much money over the years due to an unexpected event impacting a concentrated position in their portfolios.

What is a Concentrated Position?

The term “concentrated position” could mean different things to different people. We define concentration as any single position that is three or more times larger than an average position in a portfolio. (Our definition does not apply to mutual funds, exchange-traded funds [ETFs] or other potentially diversified investment vehicles.) Concentrated positions can end up in a portfolio for many different reasons: they can come from a successful investment; they can be inherited from a parent or grandparent; or they can represent a percentage of ownership in a current or former employer.

  1. Concentrated positions can make portfolios more susceptible to “lightning strikes”: A concentrated position can be like a tall tree in a lightning storm. While this risk may be obvious, what might surprise investors is the frequency at which portfolio “lightning strikes” occur. The risk that a single position could underperform the market by a significant margin – say 15% annually – is not insignificant. For example, over the last 25 years, on average 27% of the companies comprising the current S&P Composite 1500 Index have underperformed the index by more than 15 percentage points in a single year (Chart, above). In fact, in years like 1998, 1999, and 2020, more than 40% of companies underperformed by that margin. This is one of the many reasons that concentrated positions are often not permitted in the institutional management world and can be viewed as a potential ‘breach of fiduciary duty.’
  2. Concentrated positions in the stock of one’s employer can be especially dangerous, in our view: We invest for many reasons, but one of the primary objectives is to protect against an uncertain future. We believe a properly structured investment portfolio can act as an income supplement during periods of wage softness or unemployment. For this reason, we think a concentrated position in the stock of an employer is especially dangerous. There is typically a strong correlation between the performance of a company’s stock and the compensation and job security of that company’s employees. During those periods when job security is low and compensation is most under pressure, an investor with a portfolio dominated by the stock of their employer could likely find their financial hardships exacerbated. In the last twenty years, ex-employees of some of America’s most well-known companies have had to learn this lesson the hard way.
  3. Concentrated positions can force sub-optimal strategies: Generally speaking, an investment plan with significant limitations and restrictions is more likely to produce sub-optimal risk-adjusted performance. In our view, investors who ask their financial advisors to manage around or ignore a concentrated position are making a choice to hold a potentially inferior portfolio and accept inferior risk-adjusted returns. The more a concentrated position underperforms, the more difficult it becomes to execute a well-devised investment plan. A 20% position in a stock that underperforms the market by 20% in a single year costs the entire portfolio 400 basis points. Concentrated positions also present the greatest risk to those investors who regularly rely on withdrawals from their portfolio to supplement their income. An investor who takes systematic withdrawals will be forced to increasingly eat into the healthy portions of their portfolio to compensate for the decline in their concentrated position. Diversification does not ensure a profit or protect against a loss.

Lessening Concentrated Position Risk in 4 Steps:

  1. Accept the Situation: The first step of any treatment plan typically involves the acceptance that there is a problem. Concentrated positions present significant portfolio risk, where the upside opportunity rarely outweighs the downside risk. We believe that recognizing the controlling risk is a ‘must’ and not a ‘nice to have’ will make the next three steps easier.
  2. Create a Plan: Hope is not a strategy and without a plan, concentrated position risks can be compounded. This is where a financial advisor can help. A well-structured plan should address the position, but also include additional measures that can be taken to further address portfolio risk. For example, eliminating a portfolio’s allocation to other highly correlated assets, like other stocks in the same industry, can reduce the portfolio’s susceptibility to the concentrated position, in our view.
  3. Execute the Plan: The intent of an execution plan is to reduce the risk of ‘bad timing’. The best execution plans, in our view, are to incorporate a. Immediacy, b. Opportunism, and c. Gradualism. Behavioral finance pitfalls like ‘high-water marks’ and/or ‘low-cost bases’ should be considered but not impede addressing concentrated positions. Value-added solutions such as tax management or tax transition overlay services can further assist in execution.
  4. Adjust the Plan: Volatile market environments lead to changing investment landscapes. As the landscapes change, so should the execution plan. For example, periods of significant market weakness often provide windows to accelerate execution plans for tax-sensitive portfolios since capital losses in the portfolio can be netted against capital gains in the concentrated position. Any reduction in taxes would depend on an Investor's tax situation.
