Just read an article about it, and the market is over reacting, as it is just a proposal, and it is not as big a deal as it sounds. If it was being implimented TODAY, I would say it would start a big sell off, but just like with Brexit, it would not last more than a day or two.
WAtching the market, will sell the rest of my sds if we sell off into the close big time on this bogus news. Otherwise, will hold onto my 50% long sds, and add if we rally next week, or sell it on further drops
News like the above moved oil prices almost 5% in minutes, why trading futures is risky.
