"Sebi's framework addresses this issue by establishing a mechanism to determine the -- the price of a stock before the rumour surfaced.

"This price would be used for transactions unless the rumour itself caused price fluctuations in subsequent trading days," Trivesh, Chief Operating Officer of , said.

In its circular on Tuesday, Sebi outlined the framework for calculating the adjusted Volume Weighted Average Price (VWAP) for considering unaffected prices in transactions.

The guidelines also mandates that the adjusted VWAP be calculated by excluding the price variations attributable to the rumour, thereby reflecting the stock's value before the market reaction to the rumour.

The aim is to exclude price disruption caused by rumours while determining the price for acquisition.

Azeez further said the core objective of this framework is to ensure that stock prices used in transactions are not artificially influenced by speculative market activity. Sebi aims to establish a more accurate and mechanism, by identifying and excluding the WAP variation caused by rumours.

This approach helps in mitigating the risks associated with price manipulation and ensures that the transactions are based on their true value.

The unaffected price will be applicable for a period of 60 days or 180 days based on the stage of a transaction, from the date of confirmation of the market rumour till the "relevant date" under the existing regulations.

Tradejini's Trivesh said the new guidelines offer several benefits such as reduced market manipulation, fair valuations and increased investor confidence.
