Market preview: Shares are set to open lower, with S&P futures -0.3% and extending losses after durable goods dropped more than expected in April. Markets aren't helped by Applied Materials falling after issuing an earnings warning, nor by lackluster trade in Asia and Europe. Crude oil slips to $99; gold and silver are up.
