The Bias of Hedging on Implied Delta

Summary

In this episode the host dives into the often‑overlooked importance of delta, arguing that "delta is god" and exploring how mis‑estimating implied volatility when delta‑hedging can bias P&L. Three lenses are offered: a pure quant perspective, a trader‑focused quant view, and a Moontower‑style narrative, each explaining how hedge‑vol choice impacts the profit path of delta‑hedged straddles. The discussion also extends to how non‑option traders can mimic options‑like payoffs and manage the same delta risk. Throughout, the host emphasizes making ex‑ante decisions with clarity and accepting outcomes regardless of hindsight.
