Trading in the U.S. index futures suggests that Wall Street could regain the momentum that faltered yesterday. The major U.S. index futures are notably higher early Wednesday, towing in line with the sentiment in the rest of global markets. Commodities are continuing to see strength, especially oil, which is now inching closer to the $50-a-barrel mark. Earlier in the global trading day, the Bank of Japan opted to stand pat despite expectations for additional stimulus. Data released across the Atlantic was largely mixed. Earnings season is slowly unfolding, with Monsanto (MON) and Constellation Brands (STZ) among the noteworthy companies due to report today.
