NEW YORK (CNNMoney) -- U.S. stocks could struggle Friday on investor disappointment that Federal Reserve Chairman Ben Bernanke did not signal more stimulus is on the horizon.
Dow Jones industrial average (), S&P 500 ( ) and Nasdaq ( ) futures were all following overseas markets lower. Stock futures indicate the possible direction of the markets when they open at 9:30 a.m. ET.
Overseas markets were selling off in reaction to testimony from Bernanke to a congressional panel Thursday. He said the U.S. central bank stands ready to act, but gave no indication that additional asset purchases are imminent.
The comments took the air out of an earlier rally sparked by a surprise rate cut by the People's Bank of China.
Asian markets, which had all closed Thursday ahead of both the Chinese rate cut and Bernanke comments, ended Friday trading lower, with the Shanghai Composite () closing down 0.5%, the Hang Seng ( ) in Hong Kong losing 0.9%, and Japan's Nikkei ( ) falling 2.1%
European stocks were lower in afternoon trading. Britain's FTSE 100 () slipped 0.8%, and the DAX ( ) in Germany fell 0.7%.. France's CAC 40 ( ) declined 0.6%
Art Hogan, managing director at Lazard Capital Markets, said that investors should not have been surprised that Bernanke didn't signal more stimulus in his testimony. But he said hopes had been raised by comments from other Fed officials, including Vice Chairman Janet Yellen, prior to his comments.
Hogan said beyond the disappointment in Bernanke, many investors want to be cautious heading into the weekend, especially with China due to report on inflation and reports that there could be some decision about European help for Spanish banks.
"Fridays can be difficult because weekends have been tumultuous lately," Hogan said.
Spain needs to recapitalize its banking sector, but its treasury minister said earlier this week it will need help from Europe to do so because the country was at risk of being shut out of the financial markets.
Worries about Europe eased slightly Thursday after Spain held a successful bond auction. But Spain's problems are far from solved, however. Ratings agency Fitch moved Thursday to downgrade the country's credit rating to "BBB" from "A." and warned the country's debt is at risk of another cut into junk bond status.
Investors will be mulling new U.S. economic reports that showed a smaller U.S. trade deficit and a wholesale inventories report due later Friday morning, while also staying tuned for further news on Europe's debt crisis.
U.S. stocks ended mixed Thursday, trimming gains from earlier in the day. Investor sentiment remains in the "extreme fear" range on CNNMoney's Fear & Greed index, although they were not quite as fearful as they were a day or week earlier.
Heading into Friday trading, the Dow Jones industrial average was up more than 342 points, or 2.8%, for the week. The S&P 500 index was up nearly 36 points, or 2.9%, and the Nasdaq composite was more than 83 points, or 3%, higher.
