** UK‑based computer hardware company Raspberry Pi RPI.L up as much as 31% in second straight day of strong gains after CEO Eben Upton bought shares following a slide earlier this month that took the stock below its 2024 IPO price
** Two London traders say the driver behind the surge is not immediately clear, though the move follows a regulatory filing showing Upton bought 4,684 shares at around 282 pence each on Feb. 16
** By 1120 GMT, Raspberry Pi up about 26%, topping gainers on the FTSE 250 .FTMC. Earlier in February, the shares - still roughly 50% below a record high hit a year ago - fell below the 280‑pence IPO price
** In January, Raspberry Pi said its 2025 core earnings would be ahead of expectations but its 2026 outlook was clouded by volatility in the supply and price of memory
