Erasing early gains, the BSE Sensex fell 21 points on Tuesday to 16,536.47, as investors sold IT stocks led by Infosys ahead of its second quarter results and a weak trend in the European markets.

The BSE 30-stock barometer, Sensex, opened higher in line with Asian stocks and touched 2-week high of 16,774.12.
However, it fell as European markets opened weak and entered the negative terrain at the fag to settle at 16,536.47 -- down 20.76 points or 0.13 per cent. In last straight two sessions, it had gained 764.82 points or 4.84 per cent.
Similarly, the wide-based NSE 50-issue Nifty fell 5.25 points or 0.11 per cent to 4,974.35.
