srinir - I am not a client of Kim's but I can confirm his strategy is valid. It plays the odds of increasing volatility ahead of earnings which you can combine with knowledge that some stocks more than others tend to move on earnings. Some other stocks are in fact immobile and these groups of stocks are not static forever either. Choosing the most likely candidates is therefore essential.
I have done a couple of such trades - they have by and large either lost no or very little money and a few were good ones. You seem determined to bash the idea - its not a bad idea and a safer approach than many other option strategies. Its human nature to look for patterns in everything - even in chaos a human will discover patterns - so as far as that is concerned you are right to be skeptical. In this case though I would suggest to be a little less sarcastic and more open-minded.
