* S&P 500, Nasdaq notch all-time highs after sharp

rebound

* Heavy earnings week includes Tesla, Boeing ( BA ), P&G

* Hearing for Trump Fed pick could draw market's

attention

By Lewis Krauskopf

NEW YORK, April 17 (Reuters) - Investors will look to a

heavy week of U.S. corporate results to further fuel a stunning

rebound in the U.S. stock market, which has shaken off

war-related concerns to reach record peaks.

Hopes for a cooling of U.S.-Iran tensions have led to a sharp

rally this month, culminating with major U.S. stock indexes

minting fresh records in recent days. The benchmark S&P 500

on Wednesday posted its first record-high close since Jan

27, while the Nasdaq Composite on the same day notched

its first all-time-high close since Oct 29.

Investors are turning to a first-quarter earnings season

that is expected to be robust, providing a key pillar

buttressing bullish sentiment for stocks. Nearly one-fifth of

S&P 500 companies are slated to report results in the coming

week.

"We're certainly not out of the woods" from war-related

developments that could cause daily market swings, said Chuck

Carlson, chief executive officer at Horizon Investment Services.

"But I think the market has shifted its attention now ...toward

corporate profits and how stocks respond to those profits."

Oil prices remained at loftier levels. U.S. crude was

around $94 a barrel on Thursday compared to $67 in late

February, just before the U.S.-Israeli military strikes on Iran.

Knock-on effects of sustainably elevated oil prices including

higher inflation and higher Treasury yields could pose problems

for stocks, said Michael Mullaney, director of global markets

research at Boston Partners.

"The stock market is treating what has happened over the

last six weeks as if it has just woken up from a bad dream,"

Mullaney said. "Like ... there are no further ramifications or

repercussions from this. Which I don't agree with."

HISTORIC STOCK RALLY BACK TO HIGHS

Following the start of the war, the S&P 500's slide took the

benchmark index down 9% from its January peak. Since its recent

low on March 30, the index has stormed back 11%, closing this

week above the 7,000 level for the first time.

In looking at S&P 500 pullbacks between 5% to 10% since

1928, Bespoke Investment Group noted that the index had never

before rallied back to all-time highs in just 11 trading

sessions, as it achieved on Wednesday.

"The velocity of this ascent has been nothing short of

astonishing," Jim Reid, head of macro and thematic research at

Deutsche Bank, said in a note.

A number of megacap technology and tech-related stocks, which

have led for much of the three-year-old bull market, were hit

hard in the initial downturn. Some of those shined in the recent

rebound, such as Alphabet and Meta Platforms ( META ),

while the massive tech sector also outperformed. The

Nasdaq ended Thursday up for a 12th straight session, the first

time that has happened since the 2009 bounce that followed a

steep decline.

"If you are looking for broad participation in the market

and you are making new highs and your generals are now coming

back to life a little bit, I say that is probably something that

is pretty healthy," said Jeff Weniger, head of equity strategy

at WisdomTree.

Investors are eyeing signs of frothiness, including the surge in

shares of Allbirds ( BIRD ) after the footwear maker said it was

pivoting to AI computing infrastructure.

TESLA HEADLINES US EARNINGS AHEAD

Tesla reports on Wednesday, the first of the

"Magnificent Seven" megacaps to post results for the

just-completed quarter. Other companies to report include

planemaker Boeing ( BA ), semiconductor company Intel ( INTC )

and consumer products maker Procter & Gamble ( PG ).

Heavyweights such as Microsoft ( MSFT ), Alphabet and Meta

report the following week.

S&P 500 earnings are expected to jump about 14% in the first

quarter from a year earlier, according to LSEG IBES. Major banks

kicked off the reporting period this week, posting soaring

trading revenues after a volatile first quarter. They noted

caution about economic risks even as they said consumers and

households were resilient.

"The American consumer, while facing real pressure, has not

broken based on early Q1 bank earnings," Anthony Saglimbene,

chief market strategist at Ameriprise, said in a written

commentary.

The path of interest rates will be in focus on Tuesday, when

Kevin Warsh, President Donald Trump's pick to lead the Federal

Reserve, appears before Congress for a hearing. Trump has

seethed at current Fed Chair Jerome Powell for not lowering

rates more, but the war's potential inflationary effects have

led markets virtually to rule out rate cuts this year.

More insight into the war's economic fallout could come with

retail sales data for March, out Tuesday. With gas prices

hitting $4 a gallon in the wake of the war, investors will be

eager to see the impact on consumer spending.

"I suspect these prices aren't dropping down anytime soon

and that is going to have an effect on discretionary spending

going forward," said Robert Pavlik, senior portfolio manager at

Dakota Wealth Management. "So the claim that the U.S. economy is

in good shape is in my opinion near sighted."
