The put: Oct 2, $410 strike, 17 days out. Pays $875. Roughly a 41-in-100 chance you end up buying the shares.
On paper: 46% a year. That number assumes TSM keeps moving like it did the past two years. Take that away and it is +6% a year. That is why we say sell.
Next earnings Oct 15, after this put ends. We never sell a put across a report.
