I don't understand where size fits into the equation.
Look at the daily ranges back in 99/00, hell, even early 01. 5-10 point moves were commonplace among the higher priced stocks. Why would you have done very well if you "had size" back then, but not in 01-current??
To make the same total dollar profit on a trade in 00 as in 02, you didn't need as much size as you do now. When stocks moved one point as a matter of fact - noise, if you like - you'd only need 100 shares to make $100. If you equate a ten cent move today with a dollar move back then (not at all an unfair assumption) you need a thousand shares to make the same $100 profit.
Sure, if you had a "lotto", long only mentality back in 99 and traded big size you, of course, would have enjoyed huge profits. That's just elementary position sizing.
