The buy write index was down 39% in 08-09, thats less than the 57% of the SPX(and you just said that SPY is a good div payer). That could be the difference between a huge mistake/panic sell and someone sticking with a strategy (unless you want to claim that additional losses produce no extra pain). I suspect a buy write on the DIV was probably down by a good deal less than the ETF (had it existed back then)
Daal, let's make this easy. Pick a stock....any stock. Let's look at real numbers. I'll start. JNJ. Good as any other stock. Solid company, good cash flows, favorite among widows and orphans. Stock closed at 113.44. The Nov 120 calls are trading at .11 bid. Zero protection. Let's move down. The Nov 115 calls are .97 bid. So basically your only choice here is to go with the Nov 115 calls for .97. But the stock dropped Friday 1.43! It lost in one day 40% more then the entire monthly call premium. And you had to sell the call one point out of the money! Come on, who we kidding here. The calls didn't even protect you from a one day drop none the less a 50% crash. LOL. I just picked the first stock that popped in my head. Go ahead, show me a better one. Let the math speak for itself.
