PMS offers investors a range of specialised investment strategies to capitalise on opportunities in the market and made suitable to the needs of individual clients.

In a notification amending the Securities and Exchange Board of India (Portfolio Managers) Regulations, 1993, the regulator said the new rule will apply to new clients as well as fresh investments by existing clients.

"... for the words 'five lakh' the words 'twenty five lakh' shall be substituted," Sebi said.

It added that existing investments of clients can continue as such till maturity of the particular investment.

"PMS regulations are light touch regulation and SEBI was worried that retail investors are being drawn into it whereas their interest are not as tightly protected or guarded as it is in mutual fund regulation," Sebi Chairman U K Sinha had said after a board meeting last month.

"With the amendments, Sebi has tried to synchronise the PMS rules with actual reality of the present time. Such schemes are basically from HNIs and big investors and the Rs 5 lakh ceiling was set long back in 1993 and no longer holds good," SMC Global Securities Strategist and Head of Research Jagannadham Thunuguntla said.

Sebi had in its last board meeting on January 28 decided enhance the minimum investment amount of clients under PMS.

In the amenedments, Sebi has also said that henceforth portfolio manager will not be allowed to hold the unlisted securities, besides the listed securities, belonging to the portfolio account, in its own name on behalf of its clients.
