According to this article SEBI is planning to delist several illiquid stocks(4200) from the Indian stock market. India has a large number of stocks listed in the stock exchanges but almost no trading ever happens in quite a lot of them. And some of these stock are used for illegal transactions. I think this is welcome move from SEBI. the article has also mentioned that SEBI is planning to bring new regulation in Algo-trading which is also a need of the hour in India.
