I notice in the recent Informer newsletter, Len Yates - the President of OptionVue Systems - wrote about just this.
he looked for growth stocks that are likely to move a lot (scanned for stocks that have PEs>50, 50% year-on-year revenue growth, high price/book value, etc) and he came up with 12 candidates - one of which was Google.
He went back to see what would happen if he placed a one lot ATM straddle on each before earnings releases over the past couple years. He put the trade on the day before earnings and closed it in 1 to 3 days after.
I attached a picture of the chart of the results he had for Google in the newsletter to this post. You will notice that 7 of the 12 were profitable, but the real money came from one big move.
Most of the other stocks were also profitable over time, but again relied on one or two exceptional moves to make the money. So it seems the options are fairly valued most of the time, but that once every year or two these kinds of stocks end up moving more than the market expects and you make a killing.
The only thing is that I would guess most traders will not have the persistence to keep doing this every quarter for a couple years, basically breaking even, until they hit the big one.
I think you need to be an OptionVue 5 owner to get the Informer newsletter, but they also have free option trading articles and a free monthly newsletter at
