C is selling at $38.08. The 13-strike puts expiring in January are quoted at $20 bid, $22 asked. At my brokerage using cash for collateral, each option sold at the bid would fetch $19.40 and the margin maintenance requirement would be $152.
The nominal return for 43.6 weeks is 12.7% which is at the pace of 15.1% annualized. Given the very high likelihood of an early out, chances are that the actual annualized return will be something like 17%.
That's just an enormous return given the safety where 13-strike naked puts are being sold for a $38 stock.
