高盛表示，未来一周，商品交易顾问(CTA)将在任何情况下购买标普500指数期货。他们只是抛硬币吗？就在几天前，他们还说在所有情况下他们都是卖家。为什么当势头开始对他们有利时他们会抛硬币呢？CTAs will buy S&P 500 futures in EVERY SINGLE scenario over the next week according to Goldman Sachs. Do they just flip a coin? Just a couple days ago they were saying they were sellers in all scenarios. Why would they flip just as momentum started going their way?
