It was a third straight session of loss for stocks on Wednesday, as the benchmark BSE Sensex took a hit of 216 points, or 0.68 per cent, to close at a three-week low below the 32,000-mark on growing sense of disquiet following market regulator Sebi’s crackdown against suspected shell companies.
The Securities and Exchange Board of India (Sebi) clamped down on 331 such companies on Monday, directing exchanges to take action against them.
Investors also ran for cover after a flare-up in tension between the US and North Korea over the latter’s ballistic missile programme. They fear for the worse as both sides show no signs of backing down, according to traders.
Selling pressure built up following muted June quarter earnings by some companies, they added. It was so strong that all the sectoral indices, led by health care and auto, ended in the negative zone. The Sensex recovered partially before settling down 216.35 points at 31,797.84, its lowest closing since July 18.

The National Stock Exchange Nifty also remained under pressure and was down 70.50 points, or 0.71 per cent, to close at 9,908.05. Intra-day, it cracked below the 9,900-mark to touch 9,893.05.
"Global headwinds owing to geo-political tension between North Korea and the US provided more cues to the domestic market, which is already reeling under Sebi's regulatory pressure... Small- and mid-cap underperformed today (Wednesday)," said Vinod Nair, head of research at Geojit Financial Services.
Overseas, Asian stocks ended lower and European shares dropped during early hours. In the Sensex pack, Sun Pharmaceutical Industries was battered the most, plunging 5.13 per cent to an over four-year low, after its US subsidiary Taro Pharmaceutical Industries reported weak quarterly numbers.
