The Indian rupee is expected to reduce gains in opening trades on Thursday tracking an uptick in dollar overnight. However, investors react to firm cues from other Asian markets and a sharp fall in crude prices overnight, cushioning downside in the local unit. Overall gains, however, may remain capped as Israel prepares for a possible ground maneuver in Lebanon. Yesterday, rupee appreciated 5 paise to close at 83.58 against the US dollar, tracking a positive trend in domestic equities and a weak greenback against major currencies overseas. The benchmark 30-share BSE Sensex ended the session up 255.83 points, or 0.30 percent, at 85,169.87 while the broader NSE Nifty index closed at 26,004.15, up 63.75 points, or 0.25 percent, from its previous close.
