Wall Street looks set to shed off the negativity following the previous session’s drubbing, as traders seek out bargains amid a rebound in oil prices. The major index futures are pointing to a mixed opening on Wednesday. Asian stocks plunged earlier in the global trading days despite the release of fairly positive Chinese service sector reading. The European markets are moderately lower amid volatility. The domestic markets may also focus on some earnings reports and economic data on private payrolls and service sector activity.
