Feb 9 (Reuters) - Wall Street looked set to open slightly higher on Thursday as investors looked for catalysts in quarterly earnings and economic data.
The fourth-quarter earnings season has been largely upbeat, with combined earnings of S&P 500 companies estimated to have risen 8.3 percent, the highest in nine quarters.
However, Wall Street’s reaction to corporate earnings has been muted as investors remain cautious given the recent run-up in the market and policy uncertainty under newly elected President Donald Trump.
“The inability for the market to rally or sell off in a meaningful fashion tells you that investors are in a wait-and-see mode,” said Adam Sarhan, chief executive officer at 50 Parks Investment in Florida.
The S&P 500 has not moved more than 1 percent in either direction since Dec. 7.
“Investors are cautiously optimistic about the current environment. It’s almost like a Goldilocks situation where it’s neither too hot nor too cold,” Sarhan said.
