Feb 16 (Reuters) - U.S. stocks eked out enough gains on Thursday for the three main indexes to notch a record intraday high for the sixth straight session, helped by gains in Cisco.
The rally was sparked a week back by President Donald Trump's vow of a 'phenomenal' tax announcement. Robust economic data has also been a boost, while bank stocks have risen on prospects of an upcoming interest rate hike.
Trump tweeted on Thursday: "Stock market hits new high with longest winning streak in decades. Great level of confidence and optimism - even before tax plan rollout!"
"The market is likely to take a breather after recklessly rising to continued record highs without a pause," Perter Cardillo, chief market economist at First Standard Financial wrote in a note.
This type of action is due to the market expecting a perfect fiscal reform and that maybe placed on hold, he said.
The S&P 500 technology index rose 0.29 percent and gave the broader index its biggest boost. Cisco, which jumped 2.8 percent to $33.76 was the top stock on the three main indexes.
Adding to strong data points of late, a Labor Department report Thursday that showed the number of Americans filing for unemployment benefits rose less than expected last week.
