Kurtosis Of Returns is essential for evaluating tail risk in trading strategies. Standard deviation alone does not account for extreme events, but kurtosis helps measure the frequency and severity of outliers. High kurtosis strategies may offer high rewards but come with elevated downside risks. It also plays a key role in risk-adjusted performance metrics, providing insights into whether an asset's returns are stable or prone to sudden movements. By analyzing kurtosis, traders can better prepare for market shocks and develop robust risk management strategies.
