Aug 7 (Reuters) - U.S. stock index futures jumped on

Wednesday as risk appetite returned after a steep selloff

earlier in the week, and cautious comments on interest-rate

hikes by an influential Bank of Japan policymaker.

Global equity markets gained after Bank of Japan (BOJ)

Deputy Governor Shinichi Uchida said the central bank would not

raise interest rates when financial markets are unstable,

pushing the yen lower, boosting market sentiment.

The BOJ's 0.25% rate hike on July 31, a level unseen in 15

years, had sparked a global stocks rout as the low-yielding yen,

widely used for acquiring high-yielding assets such as stocks,

surged and investors unwound their sharp positions of the

currency carry trades.

"The silver lining is that, while the current volatility

might be painful, a reset after a period of excessive optimism

could lead to a healthier market," said Oliver Blackbourn,

portfolio manager-multi-asset team at Janus Henderson.

"It's important to understand that a soft landing is being

questioned but is not out of the question, meaning economic

resilience and declining interest rates could ultimately help to

lift risk assets again."

Despite recent volatility, the S&P 500 is still up

about 10% so far this year, while the tech-heavy Nasdaq

is up 9%, boosted by rallying tech stocks on optimism around the

prospects of artificial intelligence (AI).

Big technology names such as Nvidia ( NVDA ) and Amazon.com ( AMZN )

continued their recovery after falling sharply on

Monday, rising about 2% each in premarket trading.

Chip stocks also continued to recover, with popular names

like AMD gaining 2%, while Marvell Technology ( MRVL )

added 2.6%.

Wall Street's main indexes ended Tuesday with healthy gains

after comments from Federal Reserve officials eased worries of a

U.S. recession following weak economic data last week.

At 07:05 a.m. ET, Dow E-minis were up 324 points,

or 0.83%, S&P 500 E-minis were up 63.5 points, or 1.21%

and Nasdaq 100 E-minis were up 267.5 points, or 1.47%.

The spotlight shifted back to earnings, with Fortinet ( FTNT )

jumping 14.7% after the cybersecurity firm raised its

annual revenue forecast.

Wynn Resorts ( WYNN ) advanced 4.1% after the casino

operator posted a rise in second-quarter profit.

On the flipside, Airbnb ( ABNB ) slid 15.1% after the

company forecast third-quarter revenue below estimates and

warned of shorter booking windows, suggesting travelers were

waiting until the last minute to book due to economic

uncertainty.

Super Micro Computer ( SMCI ) lost 12.5% after reporting

quarterly adjusted gross margin below estimates. Rival Dell

Technologies ( DELL ) dropped 2.7%.

Amgen ( AMGN ) fell 3% after the drugmaker said

second-quarter profit slipped 1% as higher expenses offset a 20%

increase in revenue.

CVS Health ( CVS ) eased 2.7% after the healthcare

conglomerate cut its 2024 profit forecast, hit by increased

medical costs at its health insurance unit as demand for

healthcare services remained elevated.

The markets now await more commentary on monetary policy

from U.S. central bank officials next week, in the run-up to the

Jackson Hole event where Fed Chair Jerome Powell is scheduled to

speak.
