Should the contract expire worthless, the premium would represent a 10.59% return on the cash commitment, or 28.65% annualized — at Stock Options Channel we call this the YieldBoost. If an investor was to purchase shares of CRWD stock at the current price level of $188.26/share, and then sell-to-open that call contract as a "covered call," they are committing to sell the stock at $190.00. Considering the call seller will also collect the premium, that would drive a total return (excluding dividends, if any) of 12.11% if the stock gets called away at the May 20th expiration (before broker commissions).
