US stock-index futures drop, UPS falls

US stock futures fell as United Parcel Service Inc reduced its profit forecast and a report showed home prices dropped the most on record in April, reinforcing concern the economic slowdown is worsening.

UPS tumbled as rising fuel costs and a slowing economy forced the biggest package-delivery company to predict less second-quarter earnings than analysts had estimated.

Carnival Corp and UAL Corp, parent of United Airlines, slid as oil rose to almost $139 a barrel. European stocks fell for a fifth day and Asia's benchmark index dropped for a fourth.
