Dabba trading is an illegal form of trading in shares, where operators of such trading rings allow people to trade in equities outside the stock exchange platform.
Talking to reporters here on the sidelines of a SEBI function, Sinha said that SEBI is concerned about "dabba-trading" in Rajkot as well as other areas and has decided to take "stern action" to curb it.
"I met local brokers in Rajkot today and they informed me about dabba trading, which is popular in Rajkot as well as its surrounding areas. The SEBI has decided to take stern action to curb it," he said.
