June 24 (Reuters) - S&P 500 and Nasdaq futures edged higher

on Wednesday, rebounding from two straight sessions of declines,

as investors returned to technology shares after a steep

selloff, with Micron's earnings under the spotlight.

Concerns around aggressive, debt-backed spending by

hyperscalers and a potentially more hawkish Federal Reserve

fueled the downturn in previous sessions, wiping off more than

$1 trillion in market value from the Nasdaq 100.

Memory chipmakers moved higher in premarket trading,

following a sharp plunge in the previous session, with Micron

Technology ( MU ) and Sandisk ( SNDK ) adding 3.8% and 2.9%,

respectively.

The choppy backdrop in equities has intensified focus on

Micron's results after the bell, as it is a key beneficiary of

surging demand from companies investing billions in AI

infrastructure. The stock has surged more than 268% in 2026,

despite a 13% drop on Tuesday.

"We will all be looking at Micron since that is a

representation of what we've seen in this rally. I think people

are going to get the blowout quarter that they expect, but I

don't expect the stock to continue to rise," said Jay Woods,

chief market strategist at Freedom Capital Markets.

"It's fallen (after) six of its last eight earnings reports,

even though Micron has reported blowout earnings."

At 06:35 a.m. ET, Dow E-minis were down 50 points,

or 0.1%, and S&P 500 E-minis were up 15.5 points, or

0.21%. Nasdaq 100 E-minis were up 164.25 points, or

0.55%.

Investors continued to monitor Middle East developments

after the U.S. and Iran offered conflicting accounts on a range

of key issues including financial incentives for Iran, control

over the Strait of Hormuz and Israel's war in Lebanon.

Optimism surrounding an end to the war and strong earnings

growth expectations have put the S&P 500 on track for its

strongest quarterly gain in six years, despite expectations of

higher interest rates.

Traders are adding to bets of a second rate hike from the

Fed by December-end, according to CME Group's FedWatch tool,

from prior expectations of a single 25-basis-point rise, after

new chair Kevin Warsh emphasized the need to curb inflation.

The closely watched Personal Consumption Expenditures Price

Index, the Fed's preferred inflation gauge, could offer fresh

insight on the monetary policy path on Thursday. Economists

expect a rise to 4.1%, more than twice the central bank's

target.

Among early movers, Cerebras Systems ( CBRS ) tumbled 13.3%

after the chip designer forecast full-year profit margins would

drop below first-quarter figures in its debut report after going

public.

FedEx ( FDX ) slid 7.1% after reporting that margins in its

core delivery segment shrank in the latest quarter from a year

earlier.

Alphabet shares were marginally up after S&P

Global said the Google-parent would join the Dow Jones

Industrial Average, replacing Verizon Communications ( VZ ).
