Stock index futures are pointing to a lower open on Wall Street as the dollar, which powered Monday's huge rally, is little changed.
Investors are pausing after sending the Dow Jones industrials up 200 points for the second time in three days. They believe the greenback's continuing slide will keep interest rates low, and that has enabled many investors to look past some of the economy's trouble spots, including rising unemployment. Some analysts, though, are warning that this rally, which has taken stocks to new highs for 2009, is unwarranted.
Markets overseas remain higher Tuesday, catching up to the advance in the U.S. on Monday.
