The Sensex shot up by 193 points in opening trade today on a flurry of buying by funds, driven by firm Asian bourses. The 30-share index, which had gained 23 points in the previous session, spurted by 193 points, or 1.13 per cent to 17,188 points. The wide-based National Stock Exchange index Nifty also moved up by 58 points to 5,147 points during the early trade. Stock brokers said trading sentiments were mainly helped by a strong rally on other Asian bourses after the weekend rally on the US markets on encouraging jobs and consumer data.
