Nairobi Securities Exchange (NSE) investors can now buy and sell shares of any company within a single trading day. This would allow them to profit from instant price movements triggered by events like profit announcements. The NSE on Tuesday received approval from the capital markets authority (CMA) and will roll out the practice—usually called day trading—on November 22. *** traders will be allowed to purchase or sell a security within a single trading session or multiple times over the course of the day. This will give investors a chance to profit from events that trigger short-term share movements such as when companies announce results, key executives exit abruptly or government announces new policies.
