London | Britain's best-known eurosceptic, Nigel Farage, likes to claim his share of responsibility for delivering Brexit at the June 2016 referendum. In that case, the former financier should probably also take some credit for turning his country's stockmarket into something of a Nigel No Mates.

Even four years later, and for all of Prime Minister Boris Johnson's boosterish talk about the potential and prospects of post-Brexit Britain, UK equities trade at a stubborn discount to European and American stocks.
