exactly... that's what I did personally.
But i'm following the stock, fundamentally.
So it was my opinion, though long term I want to hold this stock, that short term the conference call would generate some news that the market would react to unfavourably.
If the underlying stayed flat, I would just sell the put and lose on commissions and b/a spread
If it rallied, well then I didn't make anything, I had to take that risk.
If it fell, then I sell the put for a profit, thereby reducing my cost for the underlying. Book value still shows up as my original price I paid, and the "protection" shows up in the cash balance.
What I wanted was the flexibility to evaluate if I still wanted to invest in this company post earnings w/out placing a stop loss.
I wouldn't do it for every stock I have, I just had a strong opinion about this particular case.
