Deep dives
Understanding Skewness of Returns
Skewness refers to the shape of the distribution of investment returns, indicating whether potential outcomes lean towards positive or negative extremes. A positive skew suggests a higher likelihood of achieving substantial gains from investments, even if the average returns appear modest. For instance, individual stocks historically show a strong positive skew, indicating that they have a greater chance of yielding significant returns compared to their average performance. Recognizing this can help investors distinguish between opportunities that, at first glance, may seem similar in risk and return profiles.
Implications of Diversification on Skewness
While diversification is commonly regarded as a strategy to mitigate risk, it surprisingly tends to diminish the chances of large returns, flipping the skewness to negative. As an investor adds more stocks to their portfolio, the potential for outlier gains becomes offset by individual stock performances, leading to a more stable yet less exciting return profile. This counterintuitive insight highlights that constructing a diversified portfolio could inadvertently limit access to those extraordinary investment opportunities. Therefore, investors focused on maximizing returns may need to reconsider the extent of diversification they employ.
The Role of Company Type in Investment Returns
The characteristics of the companies in which one invests significantly influence the skewness of returns, with portfolios focusing on smaller companies showing more potential for positive skew. Established large companies often yield more negative skew, indicating lower chances for substantial outlier gains despite their stability. Surprisingly, the analysis extends to growth and even green companies, which also demonstrated negative skew due to inherent volatility and uncertainty. This observation prompts investors to consider not just company size, but also growth potential and market dynamics when seeking high-return opportunities.
