Nasdaq Goes Red

The Nasdaq has fallen into negative territory again today as other major U.S. stock indices cling to modest gains.

The iShares Nasdaq Biotechnology ETF, which has lost more than 20% of its value since late February, is up about 0.4% today, however.

The charts below show movements in various markets. Across the top, from left to right, are S&P 500 futures, the U.S. dollar-Japanese yen exchange rate, and the euro-U.S. dollar exchange rate. Across the bottom are gold futures, five-year U.S. Treasury note futures, and December 2015 eurodollar futures.
