The only risk to the writer is that the stock will be called away, thus limiting the upside potential. 17. All of the following factors affect the price of a stock option except A. the risk‐free rate. B. the riskiness of the stock. C. the time to expiration. D. the expected rate of return on the stock. E. none of the above. 6 A, B, and C are directly related to the price of the option; D does not affect the price of the option. 18.
