For Tiedemann Investment Group, whose deals-focused hedge fund has never lost money, the U.K. is proving a hotbed of opportunity. The New York-based firm has built a 550 million-pound ($761 million) wager on companies engaged in U.K. deals this year, according to Drew Figdor, who runs TIG’s $3.2 billion investment strategy. “One of the themes running in this market is overbidding and shareholder activism and we see that has created optionality at a very reasonable cost,” Figdor said in an interview.
