Subject: Re: A mechanical strategy
I'm not Mark, but I found my long-forgotten copy of the book. There are very concrete rules, but I'd rather not provide the specifics so as not to violate the copyright. But basically, one would compare the value of a stock holding to its prior month's prior month's value and then make buy/sell decisions based on the amount of increase or decrease. There is also an upward ratchet to add each time a purchase is executed so that theoretically the portfolio continues to keep more and more of the profit as it continues to grow.
