I therefore see signs of modest overvaluation in these options. Hence, selling the straddles is a good idea from a theoretical standpoint.Investors may also be interested in selling call options against the stock to lower the cost basis of their holdings:(Source: optionsprofitcalculator.com)On the one hand, this will limit expected returns.
