Trading restrictions imposed by SEBI have inflicted pains on over 36 lakh investors, including big guns like Rakesh Jhunjhunwala. The trading restrictions on 331 stocks include prominent ones such as Prakash industries, which has a market capitalization of over Rs. 100 crore. 

Prakash Industries (where Jhunjhunwala owns over 1%, and is also held by institutions and mutual funds) wrote a letter to SEBI protesting the move, saying, "We are not a company which can by any stretch of imagination be termed as a shell company. We are a healthy profit making company having an annual turnover of Rs 2,400 crore and profit of Rs 78 crore during the last year of FY17.”

Prakash Industries said it has paid more than Rs 675 crore as excise duty and income tax in the last three years. "It is therefore clear that the direction is misconceived", the company wrote, "and the data collected by the MCA is totally incorrect."
