June 4 (Reuters) - S&P 500 and Nasdaq 100 futures fell

on Thursday, as Broadcom's ( AVGO ) revenue miss pressured chip stocks,

while equity investors took a breather after a strong rally to

record highs.

Broadcom ( AVGO ) shares slumped 13.5% in premarket trading

after the chipmaker also stuck to its long-range forecast of

$100 billion in sales from its AI chips. The stock, which has

climbed nearly 55% this quarter, could shave off over $270

billion in market value, if losses sustain through the session.

"Broadcom ( AVGO ) is finding that meeting and even slightly beating

forecasts is not enough when the market is holding it to such a

high standard," said Dan Coatsworth, head of markets at AJ Bell.

Other chipmakers also fell with Micron Technology ( MU ),

Advanced Micro Devices ( AMD ), Marvell Technology ( MRVL ) and

Qualcomm ( QCOM ) down between 4.1% and 7.4%.

The record-setting rally on Wall Street has stalled this

week, putting at risk the series of nine straight weekly gains

for the S&P 500, as investors weighed a renewed flare-up in

hostilities between the United States and Iran.

Although the two sides agreed to a ceasefire in early April,

talks to end the war and reopen the Strait of Hormuz have made

little progress, threatening to keep oil prices elevated and

stoke inflation.

"The shift feels less like a fundamental change in narrative

and more like a combination of profit-taking, stretched

positioning and a reassessment of geopolitical risks after weeks

of almost uninterrupted gains," said Daniela Hathorn, senior

market analyst at Capital.com.

At 06:47 a.m. ET, Dow E-minis were up 204 points, or

0.4%, S&P 500 E-minis were down 36.75 points, or 0.49%,

and Nasdaq 100 E-minis were down 369 points, or 1.2%.

An ISM survey on Wednesday showed the U.S. services sector

expanded in May. Weekly jobless claims data, due later in the

day, will be the last economic reading before Friday's broader

monthly employment report.

The data will give new Federal Reserve Chairman Kevin Warsh

a fresh read on the U.S. labor market as he heads into his first

policy meeting this month, at a time when U.S. consumers are

under strain from Iran war-driven price pressures.

Traders see a 75% chance of a 25-basis-point rate hike

before the end of the year, LSEG data showed.

Federal Reserve Bank of Richmond President Thomas Barkin and

San Francisco Fed President Mary Daly are also due to speak on

Thursday, among the last appearances before the Fed's

pre-meeting blackout period.

Among market movers, CrowdStrike ( CRWD ) slumped 10.4%

after the cybersecurity company reported a rise in its

first-quarter operating expenses.

An investor roadshow for Elon Musk-led SpaceX

begins on Thursday ahead of its market debut on June 12. It aims

to raise $75 billion in a record IPO that would value it at

$1.75 trillion and rank it among the top 10 U.S.-listed firms.
