“…Directional trading is another prime trading strategy in the options market that distorts options prices (e.g., put‐call parity violation) and adds significant noise to implied volatility (Cremers & Weinbaum, 2010; Easley, O'Hara, & Srinivas, 1998). Both theoretical (Capelle‐Blancard, 2001) and empirical works (Chakravarty, Gulen, & Mayhew, 2004; Han, Kim, & Byun, 2017) support the notion that directional traders move away from the options market during periods of high uncertainty. In sum, under high uncertainty, implied volatility is largely determined by volatility‐informed traders (rather than directional traders), which makes it highly informative of future volatility.…”
