New York (Reuters) - Wall Street closed little changed on Monday as investors searched for fresh catalysts and showed concerns about fully-extended share prices after a five-week rally.
The session, which closed slightly higher and opened slightly lower, followed a market-friendly move by the U.S. Federal Reserve last week that pushed the S&P 500 and Dow into positive territory for the year.
"I think people are starting to become concerned about valuation here," said Stephen Massocca, chief investment officer at Wedbush Equity Management in San Francisco. "Given the rally that we've had over last few weeks, stocks are extended and susceptible to bad news."
The Fed's decision to cut the number of expected rate hikes this year to two was among several recent measures by central banks to support growth and calm turmoil in global financial markets.
While the U.S. economy could continue to recover moderately, the market would react to negative surprises in European and Chinese data in coming weeks, said Lisa Kop, head of traditional investments at U.S. Bank Wealth Management in Minneapolis.
