Banks, industrial and energy stocks edged higher, with Bank of America BAC.N, Caterpillar Inc CAT.N and Chevron Corp CVX.N gaining between 0.5% and 1.1%. Tesla Inc TSLA.O gained 3.8% after star investor Cathie Wood's Ark Invest funds bought a further $171 million worth of the company's shares in the wake of a sharp fall in the electric-car maker's stock. Markets were also reassured by comments from Federal Reserve Chair Jerome Powell, who on Tuesday pushed back on suggestions that loose monetary policy risked unleashing inflation.
