137 days is a bit far out for me to go with a covered call. For those of you who think Cummins, CMI, is a solid enough stock to take this "time" risk, look at the juicy return.
A September call provides for three income payments; (1) the call premium, (2) the May dividend and (3) the August dividend. And, it places your shares under contract so you can't sell them if you need or want to. Moreover, the stock could soar and you would miss out on selling two shorter calls.
P/E is a touch over 14 so you may be paying a fair price if you added today and sold this call.
