The Sensex shed over 41 points in the opening trade on Tuesday, snapping the two-session winning streak as investors sold stocks to book profits at existing levels amid a mixed global trend. The 30-share index, which gained nearly 130 points in the past two sessions, fell by 41 points, or 0.24 per cent to 17,061 points in the opening trade. The wide-based National Stock Exchange index Nifty dipped by 18 points, or 0.34 per cent to 5,106 points. Brokers said emergence of profit taking by funds as well as retailers and mixed trend on the other Asian bourses mainly dampened the trading sentiments.
