Stock exchanges and market regulator Sebi immediately began looking into the matter to probe any possible foul play after a huge sell-off was witnessed in shares of more than a dozen companies towards noon, a senior official said.
While the problems were initially limited to about 10-12 stocks initially, the panic selling was seen spreading to other companies from the sectors of affected stocks, he added.
As per the stock exchange data, Core Projects was down 62%, Welcorp was down 25%, while Aanjaneya Lifecare, ABG Shipyard, Flexituff and Gemini Comm were down 20% each.
Besides, shares of Orbit Corp, Eros International Media, Opto Circuits, Saamya Biotech, Videocon Industries and Sanraa Media were also down by over 10%.
Sources said that the mid-cap crash could have been triggered by huge sell orders placed by certain connected entities and the matter was being probed.
The BSE Midcap and Small-cap indices were down 1.33% each, although the benchmark Sensex was almost flat with a marginal decline of 0.09% at 19,300.45 points.
