The idea is simple, appealing, the logic correct but it is very difficult to execute - didn't work for me.
The devil is in the details. Very few can find a working process using this concept. Why? Without good luck or good timing, you will mostly be running in place, year after year. Imaging you doing this since 2009, in 9-10 years, your returns would be near zero, if like him, you bought DOTM puts and waited for black swans while others were making 20% a year in returns year after year.
I suggest you back test this method and hunt for a process that could work using this strategy, maybe you can find something workable. Like MrScalper said, this time is not different and the black swans will surely be in our future, but no one knows when.
