Rolls-Royce shares fell 2.44% to 1,161 pence Friday, extending losses and leaving the stock 18% below its late-February peak. The company bought back 2.47 million shares this week as part of a planned £2.5 billion program. European stocks posted a third straight weekly decline, with the FTSE 100 down 1.4%. Rising rates, oil prices, and inflation weighed on the sector despite Rolls-Royce’s upgraded profit targets.
