The Black-Scholes model may not be correct, but that doesn't mean it's useless. Even relaxing the assumptions, it still allows mathematicians to assert relationships between various market quantities. Today, Jacob joins Mike and Nick to explore

Moments, such as standard deviation and skewness, are statistics that can help understand the shape of distributions. For market returns, the VIX tries to describe the standard deviation; SKEW is another CBOE index that attempts to capture the
