FORTUNE — Travis Lewis, an independent investor who studies the Apple (AAPL) options market, has long maintained that trading in puts and calls has become the tail that wags the underlying securities’ dog — especially for Apple options, the most heavily traded derivatives by volume, and especially since trading in those options went weekly in the summer of 2010.
To test his theory, Lewis began buying and selling Apple shares using what he calls the Poorman’s Algo (for “algorithm”) and tracking the results.
He explained it in a June 2012 Seeking Alpha post:
If this is a tradable pattern, you should be able to make money by doing the opposite: i.e., buying the stock at the close of trading Friday and selling it at Tuesday’s close, and that’s what he did.
Did it work?
According to Lewis, his Poorman’s Algo (so-called because you don’t need a PhD. to set it up) has paid off nicely for each of the last three years.
