Raspberry Pi is trading at £633.50, down 11%, with no new company-specific announcement explaining the September 28 decline. - September 24’s record interim results showed revenue up 90% and adjusted core profit more than doubled; Reuters reported an upbeat annual outlook. - A September 25 report attributed the subsequent fall to profit-taking after the results-driven rally. - September 28 markets faced rising oil prices, higher Treasury yields and renewed U.S.-Iran tensions; evidence does not establish these as Raspberry Pi’s cause.
