X Factor Investing

I hope everyone read the disclosure at the bottom of the article:

"Each of the companies above qualifies for inclusion in the X Factor Index as of this writing, however, this may not have been the case in June 2011. Therefore, the hypothetical 10-year performance of the portfolio above is potentially misleading."

Given this disclosure, I propose the Y Factor. I looked at what big stock has had the best average return over the last 10 years. Using the criteria I found Netflix was the best among the stocks I researched, so I made the Y Factor index consisting only of Netflix stock. By using backtesting over the last 10 years I found the following:

If you had invested $100k in the Y Factor 10 years ago you would have $6M!

How do you filter for companies that meet these criteria? Do you pay for the data?
