MRK Options FAQ

MRK's 60-day historical volatility is 21.4%. Historical volatility measures how much the stock price has fluctuated over a recent period. AllInvestView calculates this from daily closing prices and uses it as an input to the Black-Scholes model for pricing options. Higher volatility means higher option premiums, which benefits sellers of covered calls and cash-secured puts.
