Aug 23 (Reuters) - U.S. stock index futures rose on

Friday with investors awaiting Federal Reserve Chair Jerome

Powell's comments at the Jackson Hole Economic Symposium for

clues on interest-rate cuts in the world's biggest economy.

While minutes from the Fed's July meeting this week showed a

number of policymakers were ready to consider rate cuts come

September, Powell's speech could offer insights on the pace of

easing and how the central bank will respond as the economy

evolves.

Powell is scheduled to speak at 10 a.m. ET (1400 GMT) at the

annual global gathering of central bank officials at Jackson

Hole, Wyoming.

"The question is whether he will go as far as opening the

door to a 50 bps move - if not in September, at a later point

this year," said ING strategist Francesco Pesole.

Traders have fully priced in a scenario where the Fed begins

easing interest rates at its Sept. 17-18 meeting, with a 73.5%

chance of a 25-basis-point rate cut, according to CME Group's

FedWatch tool.

Recent data including weekly jobless claims and payrolls

revisions signaled the U.S. economy was slowing, albeit

gradually, assuaging fears over a sharp downturn.

That has helped Wall Street's three main indexes recover

from a plunge earlier this month triggered by a dour July

employment report and yen carry trade. The S&P 500 is now

about 1.8% away from a record high touched in mid-July, after

falling as much as 9.7% from that level.

At 06:53 a.m. ET, Dow E-minis were up 159 points,

or 0.39%, while S&P 500 E-minis were up 0.58% to 5,626.5. The

Nasdaq 100 E-minis were up 174 points, or 0.89%.

Chip stocks such as Nvidia ( NVDA ), Broadcom ( AVGO ) and

Qualcomm ( QCOM ) climbed more than 1.2% each in trading before

the bell, rebounding from sharp losses in the previous session.

The Philadelphia chip index notched its biggest daily

drop in three weeks on Thursday.

Rate-sensitive growth stocks such as Apple ( AAPL ) climbed

0.6%, while Amazon.com ( AMZN ) added 1% and Tesla rose

more than 1.5%, looking to bounce back from Thursday's losses.

Workday shares jumped 12.5% after the human

resource software provider beat market expectations for

second-quarter revenue and announced a $1 billion stock buyback

plan.

Cruise will offer its autonomous vehicles on ride-hailing

platform Uber ( UBER ) starting next year, the companies said,

as the General Motors ( GM )-backed robotaxi firm attempts a

comeback, sending shares of the automaker up 1%.

Ross Stores ( ROST ) gained 5.6% after the discount retailer

raised its fiscal 2024 profit forecast.

Later in the day, data from the U.S. Commerce Department's

Census Bureau is expected to show new home sales steadied in

July after hitting a seven-month low in June.
