Moments after stocks stumbled briefly in the red after the latest disappointing, and rather stagflationary Manufacturing ISM print, the S&P spiked higher following a Trump tweet in which the president said he just had a "very good" conversation with Chinese' president Xi, in which the emphasis was on trade and added that "discussions are moving along nicely."

Just had a long and very good conversation with President Xi Jinping of China. We talked about many subjects, with a heavy emphasis on Trade. Those discussions are moving along nicely with meetings being scheduled at the G-20 in Argentina. Also had good discussion on North Korea!

Of course, with China keeping radio silence on the topic of trade talks, it is likely that Trump is simply posturing ahead of the mid-term election next week; alternatively he may simply be building up hope for something positive out of the G-20 meeting.
