200 listed companies on SEBI’s radar, suspected of manipulating share prices

New Delhi: The Securities and Exchange Board of India is stepping up its efforts to tackle market manipulation and will launch a large-scale investigation into alleged pump-and-dump in the Indian stock market. According to reports, about 200 listed companies are under investigation for allegedly inflating share prices to unsuspecting investors. It is suspected that these companies are manipulating share prices through pump and dump.

According to sources, SEBI has conducted search operations at more than 80 places in the last three days. The regulator has seized data from more than 100 computers and 150 mobile phones, which shows extensive digital investigation. This extensive action by SEBI is part of a comprehensive campaign being run for several months to protect the interests of investors. Investigation is still going on in this matter.
