Taylor Wimpey is trading at £92.24, up 15.2%, according to the supplied price context. - No company announcement or clearly linked explanation for the move was found in the available September 28 coverage. - A September 26 report says a proposed return of Help to Buy has put UK housebuilders, including Taylor Wimpey, in focus; it does not establish that policy news caused this move. - Latest externally available session data showed shares at 80.10p on September 25, so the reported live price jump remains unverified by those sources.
