I'm not sure I agree with that, at least as far as how I understand how it works.
I mean, sure, your EV line can't ALWAYS go up ALL THE TIME without ever going down, but I think over time, I'd much rather see it positive than negative. I mean, say you get it in good 3 times and bad once - the line will be positive... same for 300 out of 400, etc. I'm not saying you need to get it in good 400/400 times, but I would hope you're putting your money in good more often than you are putting it in bad, or else you are going to be a HUGE longterm loser.
Right?
