You can disagree all you want, but where's the evidence? I've seen one money manager who had very few losing months, but he typically made between 0.5% to 1.5% per month. Also, I only saw his track record when the markets were relatively stable. I'm not sure how he'd do during a financial crisis.
I don't have any burden of proof, as I didn't make a positive claim, you did that. You'd actually be the one with the insufficient amount of evidence to prove your position. All I said is that I disagree with the statement you made that any strategy that turns out to be pretty consistent monthly would follow a strategy with a poor risk/reward ratio.
