For new subs: volatility skew is used to gauge traders’ sentiment as they are willing to pay premium on calls vs puts and this influences implied volatility of options. The spread between options with different moneyness (term used to describe if an option is OTM/ATM/ITM) with same term (expiration) creates the volatility skew.
