Diversification Dilemma: Evaluating the Risk of Concentrated Stock Holdings

Diversification Dilemma: Evaluating the Risk of Concentrated Stock Holdings

Despite the mountain of articles available that discuss the benefits and methods of diversification when investing, there are still many situations where an investor may find (intentional or not) where they have a concentration in one or more common stock holdings in their portfolio. While there are those who espouse steel king Andrew Carnegie’s adage to “put all your eggs in one basket, and watch that basket,” modern investment wisdom and endless studies state otherwise.

What constitutes a “concentrated stock holding”? For many, a holding that makes up more than 10% of your net worth is considered as such. Most wealth managers will say that any holding that exceeds 10% of your portfolio is excessive and invites specific risks, such as: single-company risk, management risk, legal risk, and technology risk. In short, any risk that could affect the underlying company’s operations or profitability could present an appreciable risk to your portfolio and your wealth.

How Does Concentration Occur?

Most investors are acquainted with the notion of diversification, so how does a concentrated stock holding situation occur? For those who are fortunate enough to work for a company where a retirement benefit is the ability to acquire company stock through the company retirement plan, concentration in the employer stock is a common occurrence. If the employee takes enough advantage of the opportunities and the company does well over the years, the holding can easily exceed 10% of the company 401(k) plan.

This often also leads to another situation over time: inheriting a parent’s IRA that is heavily invested either in the deceased parent’s former company’s stock, or even if the parent was fortunate enough to get in early on a successful tech company like Apple, Microsoft, Amazon, or Google, where the stock has appreciated significantly over the years and the parent was reluctant to sell.

Why Do Investors Hold On to a Concentrated Stock Position?

Human behavior biases may lead investors to hold on to these stocks. These include:

  • Sentiment: Those who acquired employer stock may feel a strong sense of loyalty to their current or former company—due to, through their work and career, having contributed to the company’s success—and thereby to the growth of the stock over the years. Similarly, heirs of such stock may be reluctant to sell based on loyalty and affection for their deceased parent(s). Holding the stock, regardless of the merits, may trigger memories of their parent or even the experiences of their parent’s career while growing up.
  • Anchoring: Investors have a tendency to latch onto a particular holding or, more often, a value of a holding, portfolio, or even real estate value. This “anchor” is an emotional reference point, leading to avoidance behavior by not taking action to actualize a loss/the pain of that loss.
  • Overconfidence: If the stock concentration is that of a former employer or was the result of some good stock-picking, the investor may feel overconfident in their knowledge of the company and its prospects for growth or the stock’s potential for gain.
  • Regret avoidance: The investor may be reluctant to diversify the holding due to potential regret if the stock should gain further or in hopes that a current loss will turn around at some point (realized loss avoidance).

Reasons to Hold Concentrated Stock

While there are abundant studies and reasons to support the recommendation to diversify away from concentrated stock positions, there may be valid reasons to maintain one’s position:

  • The investor has reasonable confidence or knowledge about the particular company and its future prospects. Perhaps the investor is/was part of senior management or an expert in the technology or operations used by the company to achieve its business success.
  • The investor may be a major shareholder where retaining voting power is a significant objective.
  • Legal or contractual reasons that prohibit divesting the position, even in part.
  • While understanding the above-stated risks, the investor has significant unrealized capital gains in the stock and, being in the latter years of their lives, would like to take advantage of the tax laws regarding “step-up” in cost basis, where the heirs of this stock may avoid taxes on the gains when sold later.
  • The stock is a conglomerate company whose divisions and operations are diversified across many industries and sectors and is financially strong and managed well enough to withstand normal business and economic cycle fluctuations.

Getting a Second Opinion

Most investors would benefit from a second look at concentrated stock holdings and obtaining recommendations on whether to retain such positions or strategies to effectively and tax-efficiently diversify their portfolio.
