Tracking CGON historical volatility helps you see how much Cg Oncology Inc's stock price has actually moved, giving you a baseline for whether option premiums look fair, cheap, or expensive.

Historical volatility is the annualized standard deviation of a stock's past returns, typically measured over rolling windows like 10, 20, 30, or 60 days. CGON's 30 day historical volatility, or CGON HV, is one of the most widely watched readings because it balances responsiveness with stability. Comparing CGON's HV to its implied volatility reveals the volatility risk premium. When IV sits well above HV, options are pricing in more movement than the stock has actually delivered, giving option sellers an edge. When HV runs hot relative to IV, options are pricing in less movement than the stock has delivered, and buyers may be underpaying for it.
