Futures up: Dow 0.08%, S&P 0.10%, Nasdaq 0.16%

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

marginally on Tuesday as some growth and chip stocks gained,

while market participants geared up for a busy week of quarterly

earnings that could help gauge the health of America's

corporates.

Most megacap growth stocks, including Meta Platforms ( META )

, Microsoft ( MSFT ) and Tesla, edged up

between 0.4% and 1.1% in premarket trading. The tech majors are

scheduled to report their quarterly numbers this week, with

Tesla kicking off the cycle after markets close.

Apple ( AAPL ) was an outlier, down 0.4%, as market data

showed its smartphone shipments tumbled 19% in China.

Early gains in some chip stocks also offered support to

equities, with Nvidia ( NVDA ), Micron Technology ( MU ) and

Marvell Technology ( MRVL ) up between 1.1% and 1.3%.

On the docket for the day are quarterly numbers before the

bell from PepsiCo ( PEP ), United Parcel Service ( UPS ) and

General Motors ( GM ), among others.

U.S. stocks had a sharp sell-off last week after heightened

tensions in the Middle East and as markets re-evaluated their

rate-cut expectations from the Federal Reserve.

"While further volatility can be expected, especially with

ongoing attacks in the Middle East, we think a gradually

improving risk-reward outlook for U.S. stocks continues to

support our focuses on finding opportunities within and beyond

technology," Mark Haefele, chief investment officer at UBS

Global Wealth Management said in a note.

The Personal Consumption Expenditures index reading for

March, the Fed's preferred inflation measure, is due on Friday

and will help ascertain the central bank's monetary policy

trajectory.

Money markets are now pricing in just about 38 basis points

of interest-rate cuts, down from about 150 bps seen at the start

of the year.

On the data front, investors will await the S&P Global

Composite Flash PMI data for April, due after the opening bell.

At 5:34 a.m. ET, Dow e-minis were up 30 points, or

0.08%, S&P 500 e-minis were up 5.25 points, or 0.10%,

and Nasdaq 100 e-minis were up 28.5 points, or 0.16%.

Among single stocks, Cadence Design Systems ( CDNS ) lost 6%

in premarket trading after the chip design software maker

forecast second-quarter revenue below analysts' estimates.

Roblox added 3.7% after J.P.Morgan upgraded the

gaming platform to "overweight" from "neutral" on significant
