An increasing amount of investors are preparing to cut their exposure to British assets even as the view on global growth prospects has brightened, according to a survey.

Of 102 professional investors, 24% said they’re looking in the next six months to reduce U.K. holdings, according to State Street’s Brexometer Survey, a quarterly gauge of investor sentiment toward the economic impact of Brexit. That’s up from 18% in the fourth quarter of 2017.
