U.S. futures opened slightly positive, dropped, then recovered on Tuesday evening, after a massive rally and reversal during the regular session.
Dow Jones industrial average futures fell 110 points, indicating a negative opening, before recovering to 143 points up. Nasdaq futures slid 43 points before moving to 31 points up; S&P 500 futures fell 14 points then turned to show the market would open 26 points higher. The futures are lightly traded and highly volatile.
U.S. stocks closed lower, after a failed attempt to rally from the Dow's worst three-day point decline in history, as investor confidence waned amid continued concerns about China and global growth.
The Dow Jones industrial average and the S&P 500 closed about 1.3 percent lower after rallying nearly 3 percent earlier, their biggest reversal to the downside since Oct. 29, 2008. The S&P 500 remained in correction territory after falling there on Monday. The index also posted its first six-day losing streak since July 2012.
