Hi Doug, The only real defect I see in your article is the use of the $7.95 stock trade price for the full range of the time frame. I don't know when discount brokers really became the real deal but from what I understand there weren't many back in 1998 nor were their prices as cheap as that. It might not make all that much difference, not sure.
One other thing you might consider looking at is rotation among the various sectors as they go in and out of favor during the normal market cycle. You might find improved results doing this.
BTW, very clever using that set of ETFs. It seems they all started on the same day!
