Indian shares fell on Tuesday, heading for a second straight session of losses, as an unexpected regulatory order imposing trading restrictions on 162 listed entities identified as shell companies raised concerns about a wider probe into others.
Analysts attributed the move by the Securities and Exchange Board of India (SEBI) to a broad government crackdown on suspected illegal offshore transfers and tax evasion, although the regulator did not say what illegal activities the companies might have been engaged in.
The restrictions include limiting trading in the affectedcompanies` stocks to once a month and curbs in the trading of shares held by the promoters and directors of the companies - raising fears of additional measures from the regulator.
Concerns about valuations also weighed on markets. Indian stock markets have been on a record-hitting spree in the past month, with the NSE index <.nsei> breaching the 10,000-mark and the BSE Sensex crossing 32,000 for the first time.
"There has been an initial panic," said Neeraj Dewan, director, Quantum Securities, referring to the SEBI action.
"Markets are definitely stretched, they will correct at some time."
