Quote from Eliot Hosewater:
I think dandxg struck a nerve.
I recall a couple of years ago some expert (sorry no link or details), while denying the existence of a PPT, saying it would be failry easy to manipulate the stock market by buying a relatively small amount of futures (as robertstone alluded to previously).
As far as proof, if it was made public that would sort of defeat the purpose wouldn't it? There is a lot of speculation. And there is the executive order mentioned earlier, which is vague on details, but could be interpreted to allow for a PPT. There are some days where the market starts off dropping like a rock but somehow manages to reverse and maybe even close higher for no reason.
If you wanted to trade the PPT, I guess you could watch the futures market and try to figure out when they might be active, like on a day where where the market tanks, watch for an afternoon turnaround. Since they would only be in the market a few days per year it would be kind of tough to trade.
