| NEW YORK
NEW YORK The 'Trump trade' made a comeback on Thursday on Wall Street but major indexes were in and out of negative territory as former FBI director James Comey said President Donald Trump fired him to undermine an investigation into Russian meddling into last November's U.S. election.
Traders had been on tenterhooks ahead of Comey's testimony to a Senate committee, his first since being fired by Trump on May 9. His prepared remarks had been made public Wednesday.
The market's concern on the issue is whether the Trump administration can put the investigation behind it and revive momentum for their agenda of lower taxes and looser regulations. Bets on that agenda are partly behind a rally that has taken stock indexes to record highs.
The Trump 'reflation trade' that favored banks and sectors linked to infrastructure spending, among others, was back Thursday, with the S&P 500 financial sector .SPSY up 1.2 percent.
The S&P 1500 construction and engineering index .SPCOMCSE rose 1.5 percent and a gauge of construction materials' stocks .SPCOMCEMT added 1.4 percent.
"If there was something (damning) that's going to come out, as leaky as things seem to be, we would have heard something more than what we've been hearing so far," said Scott Wren, senior global equity strategist at Wells Fargo Investment Institute in St. Louis, Missouri.
Also supporting infrastructure stocks, specifically steel companies, was an announcement from Commerce Secretary Wilbur Ross that a national security review of the U.S. steel industry will seek to protect the interests of both domestic steel producers and consumers.
In his statement, Comey said the president lied in describing their encounters and that he had no doubt that Russia interfered with the election, but was confident that no votes had been altered.
The Dow Jones Industrial Average .DJI fell 19.19 points, or 0.09 percent, to 21,154.5, the S&P 500 .SPX lost 2.87 points, or 0.12 percent, to 2,430.27 and the Nasdaq Composite .IXIC added 11.27 points, or 0.18 percent, to 6,308.65.
Other analysts were not so rosy about the effect on Comey's testimony on the Trump agenda.
"It leaves us where we were before. It becomes that much more difficult for the Trump administration to put together a fiscal stimulus package," said John Canavan, market strategist at Stone & McCarthy Research Associates in Princeton, New Jersey.
"Anything they could put together with tax reform and infrastructure spending would be a lot smaller than had been expected. You are also pushing back the timing on any fiscal stimulus into 2018, possibly in 2019."
Utilities stocks fell the most on the S&P 500 as Treasury yields rose, tracking German Bund yields, after European Central Bank upgraded its growth forecast for the euro zone even as it suggested its stimulus plan will remain in place as inflation remains subdued.
The S&P utilities sector .SPLRCU was down 1.3 percent, the most for any day since early March.
Traders kept an eye on the UK as Britons voted in a snap election predicted to give Prime Minister Theresa May a larger parliamentary majority, which she hopes will strengthen her hand in looming divorce talks with the European Union.
Among specific stocks, Nordstrom (JWN.N) jumped 8.6 percent to $43.95 after the department store operator said that some members of the controlling Nordstrom family have formed a group to consider taking the company private.
Alibaba shares (BABA.N) were up 12.9 percent to $141.82 after the company said it expects revenue growth of 45-49 percent in the 2018 fiscal year.
The largest percentage gainer on the S&P 500 was Yahoo YHOO.O, which rose 9.7 percent, while the largest decliner was Advance Auto Parts (AAP.N), down 3.4 percent.
Advancing issues outnumbered declining ones on the NYSE by a 1.22-to-1 ratio; on Nasdaq, a 1.96-to-1 ratio favored advancers.
