Shares in power equipment maker Bharat Heavy Electricals Ltd (BHEL) and engineering and construction conglomerate Larsen & Toubro (L&T) dropped amid expectations for weak February industrial output data due on Thursday.
The notoriously volatile data was seen falling from the 6.8% year-on-year growth reported for January, according to traders, potentially to below 5%.
The uncertainty about the data sparked a round of profit-taking in the two stocks after both recently outperformed the Nifty's gains of 0.5% last week.
BHEL shares were down 3.5% after surging 6.4% last week.
Meanwhile, L&T fell 2.7%, wiping the gains of 2.77% over the three trading sessions in last week's holiday-shortened period.
