Stocks are falling again today, this time triggered by a steep selloff in Japan.
S&P 500 futures are down about 0.4 percent. Losses in Europe range from 0.6 percent in France to 1.4 percent in Germany, though they have climbed back near their highs of the session.
The big catalyst today is a 6 percent drop in the Tokyo stock market and a 2 percent surge in the Japanese yen. The move follows a steady rally by the Nikkei and decline in the currency since November.
