The missiles fired by North Korea early Thursday were the first weapons launches in more than two months and an apparent tactic to pressure Washington as North Korean and U.S. officials struggle to restart nuclear negotiations.
The South's Joint Chiefs of Staff said the missiles were fired from near the eastern coastal town of Wonsan and flew about 430 kilometers (270 miles) before landing in the waters off the country's east coast.
Otherwise, there was little in the way of new developments to drive trading, with many investors awaiting policy announcements by the European Central Bank later in the day and from the Federal Reserve and Bank of Japan later in the month.
On Wall Street, stocks steadily gained ground Wednesday and closed broadly higher on Wall Street as investors rewarded solid earnings results from several large companies. Industrial stocks moved broadly higher after UPS beat Wall Street's financial forecasts. The solid results from the delivery service counteracted steep drops from Boeing and Caterpillar, which both reported weak results.
The Russell 2000, which focuses on smaller stocks, outshone every other index, gaining 1.6% to 1,580.42. The S&P 500 index rose 0.5% to 3,019.56, putting it on track for a weekly gain. Boeing and Caterpillar weighed down The Dow Jones Industrial Average, which fell 0.3% to 27,269.97.
The Nasdaq rose 0.8% to 8,321.50. ENERGY: Benchmark crude oil added 18 cents to $56.06 per barrel in electronic trading on the New York Mercantile Exchange.
