Former hedge fund manager Hugh Hendry has a new gig as a property developer in the celebrity island playground of St. Barts. Hendry, 50, shut down his macro trading firm in 2017 after a 15-year run ended in mounting losses. Now he’s looking to cash in on demand for homes on the Caribbean island best known as a holiday destination for the rich and famous. He aims to raise $50 million to acquire land for development and to renovate existing properties.
