It is one of the types of statistical depictions where the kurtosis of a distribution measures the extent to which the scores bunch up together at the highest or lowest point, with the given frequency distribution.
It is used to calculate financial risks in the designated investment alternative where large kurtosis indicates a higher level of danger with a higher probability of extremely large or smaller return.
Smaller peaks are considered moderate as the probability of loss is low. In real-life situations, lows can be found in global investment-grade bonds or cash and higher levels can be seen for commodities and real estate.
Platykurtic indicates there are fewer values - in the tails and also, when close to the mean.
Such distribution is almost flat as compared to normal. This is the most advantageous state for investors seeking low-risk, while, it has a small chance of experiencing extreme returns (high or low).
