Market watchdog Sebi has said participation of large number of investors is desirable for democratising the price discovery process and making best use of the markets. The Securities and Exchange Board of India (Sebi) also said that investors will get attracted to the market only when they feel the platforms are free from manipulation and in case of any manipulation, the regulator will take suitable action. In this context, the role of surveillance and investigation departments in the regulation of any jurisdiction is important, Sebi's Whole Time Member Rajeev Kumar Agarwal said at the fourth 'Asia Pacific Regulators Dialogue on Market Surveillance' here, according to a press release issued today. Sebi hosted the two-day event in Mumbai starting September 22, in which nine Asia Pacific countries participated. Agarwal said that surveillance of the market by the regulator is very crucial for maintaining market integrity, which is directly linked to investor protection. Investor protection is the most important mandate given to Sebi by the statute and as such most of the regulations flow from this mandate, he said. "Participation of as large number of investors as possible is desirable from the angle of democratising the price discovery process as well as from the angle of making best use of the markets," he added. Agarwal also said that in view of globalisation of markets interaction amongst regulators is need of the hour. The Asia Pacific Regulators Dialogue on Market Surveillance was started three years back by the Securities Commission, Malaysia, along with other fellow regulators responsible for market surveillance in the Asia Pacific region. The aim behind this initiative is to create a platform for the regulators to come together and discuss surveillance strategies, share their views on market integrity, maintaining fair and efficient markets, among others.
