 Cocoa futures down the most in two weeks today. Improved weather in some key growing areas in West Africa are raising expectations for crop prospects in the next season. Futures down as much as 4%, the biggest drop since the start of the month. Prices, though, have soared 90% so far this year as poor harvests in top-producing nations leave the world facing a shortage. Wall Street's index is higher, Dow and S&P 500 gaining 0.5%, NASDAQ up 0.75%. Andrew O'Day, Bloomberg Radio.
