Even as Thursday’s Fed decision keeps traders on the tenterhook, Wall Street is bracing for some more immediate triggers on Tuesday. Reflecting the nervous mood, the major U.S. index futures point to a lower open in the session. Earlier in the global trading day, Asian stocks closed mostly lower as the Chinese market took another tumble and the Bank of Japan decided to stand pat despite signs of weakening of the economy. The mood across the Atlantic is also sour as traders are on Fed watch and digest some lackluster domestic data. The dollar is mixed and commodities are weaker, although oil is seeing a small bounce. Traders in the domestic markets may focus on economic readings on retail sales, industrial production and regional manufacturing activity.
