Welcome to Jamaica, Home of the World’s Best-Performing Stock Market

The Jamaican stock exchange is so obscure, even emerging-markets funds don’t go there. And it’s booming.

At the world’s best-performing stock market, things operate a bit differently than they do on Wall Street. No one complains about short sellers swooping in to drive down share prices or high-frequency traders eking out an unfair edge, because neither exist here. And forget about premarket or after-hours sessions that stretch the trading day around the clock. At the Jamaica Stock Exchange on the waterfront of Kingston Harbour, investors have just three and a half hours a day to buy and sell.

So this market isn’t ready to plug into the hyperactive trading desks of New York and London. Not yet. There are zero Jamaican stocks in U.S. exchange-traded funds, even those tracking “frontier” countries such as Kazakhstan, Sri Lanka, and Vietnam, the most emerging of the emerging markets.
