The Bombay Stock Exchange benchmark Sensex lost over 200 points at mid-session on Wednesday following widespread losses in blue chip stocks, led by capital goods, realty and metal sectors, besides weak global markets.
The BSE 30-share index, which reached an all-time intra-session high of 15,868.85 points on Tuesday, attracted profit selling and was down by 201.15 points at 15,593.77 points at 1330 hrs.
Similarly, the second wide-based National Stock Exchange index plunged 64.95 points, or 1.3 per cent at 4,555.80. It had touched an intra-session record high of 4,647.95 points on Tuesday.
Stock observers said apart from weakening global stock markets, squaring-up of positions by operators ahead of tomorrow's expiry of July contracts in the derivatives segment also pulled stock prices down.
Most of the sectoral indices were in the negative zone with sizable losses.
