Why wait 40 years? You can make 5 or so ES point everyday pretty much risk free if you buy dips and breakouts. Once in a blue moon you'll take some heat, but you would have made so much before that, that it wont hurt too much, not to mention that it will only be a matter of time before the fed step in and ramp it back up.
Certainly does seem as though the ES generally goes up. Im still making a trading plan, but have been following quite a few twitter posters who only trade long on the ES and have been doing so well for absolutely ages now. Gonna demo trade this theory soon and then put it into practice. I read lots of evidence that suggests that the market is clearly manipulated to the upside. It seems the most logical approach
