Weak European markets and summons issued on top firms in the 2G case added to the woes.

Rate sensitive bank, realty and automobile stocks saw some buying early on, but wilted later on in the session.
Capital goods, metal and PSU stocks mostly ended with sharp losses.
Oil, power and consumer durables stocks too closed weak.
IT and FMCG stocks failed to hold at higher levels.
Select pharma stocks bucked the trend.
Midcap and smallcap stocks ended mostly lower.
The market breadth was very weak.
