Many a times, stock price gap up or down following the quarterly earnings report but often, the direction of the movement can be unpredictable. Consequently, options of high cash dividend stocks have lower premium calls and higher premium puts. As above, the Black—Scholes equation is a partial differential equationwhich describes the price of the option over time.

Since the value of stock options depends on the price of the underlying stock, it is useful to calculate the fair value of the stock by using a technique known as discounted cash flow When does the option trader breaks-even on longer time periods? Solving for volatility over a given set of durations and strike does gap stock pay dividends gamma options strategy, one can construct an implied volatility surface. Some stocks pay generous dividends every quarter. When volatility is high, gamma tends to be stable across all strike prices.
Changes in volatility and its effects on the gamma
Since whoever owns the stock as of the ex-dividend date receives the cash dividend, sellers of call options on dividend paying stocks are assumed to receive the dividends and hence the call options can get discounted by as much as the dividend amount. Since a binary call is a mathematical derivative of a vanilla call with respect to strike, the price of a binary call has the same shape as the delta of a vanilla call, and the delta of a binary call has the same shape as the gamma of a vanilla call.
