Mumbai: The Bombay Stock Exchange benchmark Sensex on Wednesday shot up 434 points to over 19,696, as investors bought stocks at lower levels amid firming global trend and easing of crude oil prices.

Sensex, which had lost 440 points in the last five trading sessions, gained 434.32 points to close at 19,696.86, snapping 5-day falling streak.

The broad-based National Stock Exchange index Nifty shot up 125.80 points to 5,911.50, after a weak opening at 5,735.55 points.

The increase in the market was led by software exporting companies on expectations for robust quarterly earnings, ahead of the fourth quarter results starting with the announcement by Infosys Technologies on Friday.

The top three outsourcing companies are expected to post strong fourth quarter profits and forecast robust revenue growth for the fiscal ending March 2012 on improving global economic environment. Software exporters get about half their revenues from the US and European markets.

Besides, marketmen said investors were consolidating after selling for five consecutive sessions, amid a firming Asian trend and higher openings in Europe in view of easing crude oil prices.
