April 8 (Reuters) - Wall Street's main indexes were set

to open higher on Tuesday after a bruising selloff that has

wiped out trillions of dollars since last week, as investors

await any sign of the U.S. opening up for negotiations over some

of the aggressive tariffs.

Most megacap and growth stocks rose in premarket trading,

with Nvidia ( NVDA ) adding 4.5%, and Amazon.com ( AMZN ) and

Tesla rising close to 4% each.

Since the reciprocal tariff announcement on April 2,

concerns over a global trade war and fears of a recession in the

U.S. have gripped Wall Street, with the three major indexes

hitting around one-year lows.

The Nasdaq confirmed a bear market on Friday, while

the S&P 500 and the Dow are down more than 15% from their

record-high closes. The benchmark index neared bear market

territory on Monday, before cutting some losses.

"A bounce was inevitable at some stage... the reason is

we've had a very rapid fall and that equity investors are still

hoping that representations from countries will attempt to try

and strike a trade accord with America," said Russ Mould,

investment director at AJ Bell.

Markets continued to remain under a cloud of uncertainty

after China said on Tuesday it will never accept the "blackmail

nature" of the U.S. to Trump's threat to ratchet up tariffs on

imports from China to more than 100%.

This was in response to China's decision to impose

retaliatory tariffs to match 'reciprocal' U.S. duties.

U.S. Treasury Secretary Scott Bessent said in an interview

to CNBC on Tuesday tariff negotiations are the result of calls

from other countries, not sliding financial markets, and China's

escalation is a big mistake.

President Trump will be personally involved in trade

negotiations, Bessent said.

At 08:13 a.m. ET, Dow E-minis were up 1,201 points,

or 3.15%, S&P 500 E-minis were up 148 points, or 2.9%,

and Nasdaq 100 E-minis were up 488 points, or 2.78%.

Worries that the aggressive U.S. tariffs could spur

inflation and hamper global growth have led to greater pricing

of interest-rate cuts by the Federal Reserve.

Traders see more than 96 basis points of easing by the

December, implying three fully priced in 25-bps cuts and a 84%

chance of a fourth such a reduction, according to LSEG data.

A consumer price inflation reading is also due on Thursday,

which could offer more clues on the inflation trajectory.

The CBOE Volatility index - seen as Wall Street's

'fear gauge' - retreated to 39.78 points after rising to more

than 60 on Monday - levels last seen back in August.

Among individual stocks, chipmaker Broadcom ( AVGO )

advanced 7.4% after the company said it was launching a new

share buyback program of up to $10 billion.

Health insurer UnitedHealth Group ( UNH ) gained 7.4% after

the U.S. announced 5.06% increase in payment rates to private

insurers for 2026 Medicare Advantage health plans.

Humana soared 14.8%, while Elevance Health ( ELV )

also gained 8.1%. CVS Health ( CVS ) jumped 9.4%. The insurer

named UPS executive Brian Newman as its chief financial officer.
