British stocks haven’t suffered a major hit due to the hubbub, even as analysts warn of the potential for severe economic disruption. However, fears about the breakup may start to grow as investors return from a late-August U.K. holiday and Labor Day in the U.S., according to one smart strategist. “This is going to get quite nasty quite quickly after everybody comes back from the holidays,” says Helen Thomas, CEO and founder of Blonde Money, a macroeconomic consultant in London. “I have been calling for September as the first big wobble, and then I think it really picks up into the end of the year.” Thomas views a no-deal Brexit as the most likely outcome, and she sees U.K. equity benchmarks slumping in coming months as uncertainty rises. Brexit, with an agreement or not, is slated to occur March 29, or nearly three years after Brits voted to leave Europe’s big trade bloc.via
