The U.K.’s FTSE 100 Is ‘Having the Time of Its Life’

European stocks were broadly lower early Thursday but there was no stopping the U.K.’s FTSE 100 Index, which was heading for another record high. The U.K.’s blue-chip index jumped 0.7% in morning trading, helped by strong gains for some of its largest companies, including AstraZeneca and Unilever. Anglo American, another heavyweight, jumped 11.5% after the company confirmed it had been approached by Australian miner BHP Group over a potential merger.
