Stocks looked at a flattish open Tuesday a day after Monday's merger-fueled rally evaporated.

The S&P 500 futures were up 0.30 points and the Nasdaq futures were up by 6. Oil dropped 32 cents to $66.42 a barrel, a day ahead of U.S. data on crude inventories.

reported. The comments come ahead of a visit by President Hu Jintao to Washington this month.

The remarks come amid some nervousness in the bond market. Rising bond yields sapped the market's momentum in the closing days of the first quarter. At current levels, the yield on the 10-year Treasury note is at its highest point since June 2004, as traders have fretted that strong economic data will prevent the Federal Reserve from halting its rate-tightening campaign. The 10-year Treasury bond was yielding 4.86%.

Stocks were mostly lower overseas. In Europe, the British FTSE dropped 0.3% to 6004, the German DAX slid 0.2% to 6010 and the French CAC dipped 0.6% to 5225. In Asia, Japan's Nikkei dropped 0.2% to 17,293 but Hong Kong's Hang Seng rose 0.2% to 16,100.

That falls short of previous estimates of $145 million to $155 million and a poll of Thomson First Call analysts that pegged the company to hit $155 million in sales.
