Orders for U.S.-made durable goods sank in June, falling 2.5% on weaker demand for autos, airplanes, and computers, the Commerce Department reported Wednesday. It is the largest drop since January and follows two monthly gains. Excluding the 12.8% decrease in transportation goods, orders rose 1.1%. The decrease far exceeded the expected 0.6% fall forecast by economists surveyed by MarketWatch. Orders in May were revised lower to a gain of 1.3% from the previous estimate of a rise of 1.8%. Shipments fell 0.2 % in June, for a record 11th straight decline. Inventories were down 0.9%.
