I doubt he is selling puts on airlines since his stake in airlines is really high and he says he doesn’t want to go above 10 % and he is pretty careful . I doubt he has been doing anything the last year people has been speculating based on his filings but the etf purchases he said was done by some pension fund and kr was done by one of the money managers which I’m sure rh was done as well along with the selling of Apple. He doesn’t make too many moves other than I think he decreased his wfc pos and increased bac position. Hope this helps
