Trading in the U.S. index futures suggests that Wall Street stocks may open Tuesday’s session modestly higher, although the sustenance of the gains is questionable. Risk aversion is running deep in the markets, as the uncertainty over the global economic outlook intensifies. A deeper than expected rate cut announced by the Reserve Bank of India infused some life into the domestic markets, while the rest of the Asia experienced a sell-off. Notwithstanding the notably lower opening, European stocks have staged a fight back. Crude oil prices are modestly higher even as other commodities trade lower. A U.S. consumer confidence-reading due shortly after the markets may also provide directional cues.
