When and why is a stock under surveillance for Information List (Unsolicited SMS)?

A stock may be placed under surveillance for information list (unsolicited SMS) when there are reports of unsolicited SMS messages being sent to investors with information about the company or its stock, without their consent or request. These messages may contain false or misleading information, which can potentially manipulate the stock price and mislead investors.

The stock exchange or regulator may place the stock under surveillance to investigate the source of these unsolicited SMS messages and to ensure that investors are not being misled or harmed. The surveillance may also be used to monitor trading activity in the stock and to detect any potential market manipulation.

Investors should be cautious when receiving unsolicited SMS messages related to stock trading and should conduct their own research and analysis before making any investment decisions. They should also report any suspicious messages to the relevant authorities to help prevent market manipulation and protect the interests of investors.
