Surana has been barred from dealing in the securities markets, either directly or indirectly, for alleged fraudulent dealings in shares of P M Telelinnks and 8KMiles.
The latest Sebi order comes after SAT in January had directed the capital markets regulator to pass a fresh order within two weeks in the matter.
Surana was seeking permission to sell 40,000 equity shares of the company and deposit the sale proceeds in an escrow account.
"In these facts, allowing Surana to sell the shares of the scrip in which alleged manipulation has taken place, before the investigation is complete, may pose threat to market equilibrium and may consequently affect the rest of the shareholders adversely," it added.
The regulator said that "since the disposal of shares of the scrip under investigation itself is not allowable for these reasons, the question of keeping sale proceeds in escrow account does not arise."
