$AAOI Bought to close my Sept 29th 55Puts for 0.05. Originally sold for 1.70. One member at SMM has been commenting that Schwab ahs been pressing to borrow his shares and keeps upping the offer. I don’t know how that works. Never been in that position but it gives me a pause. Why the premiums are so juicy and what is coming down the pike. Earnings are estimated to be beginning of Nov. I may sell an Oct 06th 60 or 55 Put. Any opinions out there?
