I've back tested a few things brought up on the various AIM boards, here are the results... In general, 1. starting with 80/20 usually gives better results than 67/33 or 50/50. 2. Using a minimum transaction size of 10% stock value usually gives worse results than 5%. 3. Monthly updates usually give worse results than weekly or daily updates. 4. The decay method, recently resurrected, didn't appear to work well. The vast majority of results I saw created decreased performance. regards, Mark. <A HREF="http://www.automaticinvestor.com" target="_new">http://www.automaticinvestor.com</A>
