Trading in the U.S. index futures suggests that Wall Street stocks may open Thursday’s session on a nervous note. The global sell-off has resumed, with Asian stocks closing lower earlier in the global trading day. China bucked the downtrend with a strong move to the upside. Crude oil, though seeing an upward bounce, is at depressed levels, holding up around its 12-year lows. The European markets are tumbling ahead of the BoE rate decision and the ECB minutes. The dollar is mostly higher. The domestic markets could also react to Fed speeches, jobless claims data and earnings from JP Morgan Chase, all due in the morning.
