Platykurtic distributions are distributions in which the frequency of extreme events (whether positive or negative) is less than that found in the normal distribution. As their name implies, this type of distribution has a lower kurtosis, or level of “peakedness”, compared to the normal distribution. A kurtosis of zero (or even negative values) indicates that the platykurtic curve is relatively flat, meaning deviations from the average will be less extreme than that of the normal distribution.

Platykurtic distributions can be useful for investors looking to manage risk and maximize returns. By investing in assets whose returns follow a platykurtic distribution, the investor can reduce the possibility of large losses. Instead of negatively-skewed returns of a normal distribution, the flat curve of a platykurtic distribution indicates possible positive payoffs across a wider range of outcomes.

In addition to minimizing the potential losses associated with extreme events, the less dramatic peaks and valleys of returns associated with a platykurtic distribution also means that investors may enjoy a more consistent return with less volatility. Because there is a slower rate of return than in a normal distribution, investors may benefit from steady profits without being exposed to the large losses that can occur in a normal distribution.

In conclusion, platykurtic distributions can be seen as a more conservative approach to investing, as the lack of extreme events means the investor reduces the risk of large losses. Despite the reduced returns in comparison to a normal distribution, a platykurtic distribution provides more steady payoffs and profits, making it an attractive option for risk-averse investors.
