Shares in Berkeley Group - which focuses on London and the south east - are currently up around 2.5% despite the housebuilder reporting a 25% drop in profit for the first half of the year.
Hargreaves Lansdown analyst George Salmon says the firm's more than 5% upgrade for full year profit and a pledge to boost shareholder returns has reassured investors.
But he warns sentiment on the stock will be closely linked to whatever happens to Brexit.
"London could well be in the eye of the storm should a disorderly departure trigger a housing meltdown.
"While the shares remain something of a binary bet on Brexit in the short-term, looking further afield Berkeley’s niche operating model and enviable track record mean we think it should be a long-term winner," he says.
