European and Asian stocks were modestly in the green, with U.S. futures higher, before a critical procedural vote on a Republican health-care bill to repeal Obamacare, while Janet Yellen is set to speak in Washington at 8:45am.
It was a relatively calm overnight session in which European stocks wobbled modestly, Japan was up, China was down following the Yuan's weakest fixing since 2011 as the PBOC continues to aggressively devalue since the SDR inclusion (stoking concerns capital outflows are once again surging), EM stocks stocks were weak and the dollar was unchanged ahead of today's retail sales data and next week's Fed meeting, and then suddenly everything snapped.
