Wall Street’s optimism seems to have deserted it, as reflected by the trading in the U.S. index futures, which point to a lower opening on Friday. Asian stocks had a mixed outing, with the Chinese market carving out a marginal gain, while most other markets ended lower. The European markets are also experiencing weakness. Most commodities are weaker, although the dollar is subdued. The domestic markets may also keep an eye on wholesale price inflation report and a consumer sentiment reading, even as the focus is likely to be past this week into next week’s FOMC announcement.
