* Futures up: Dow 0.35%, S&P 500 0.44%, Nasdaq 0.58%

April 22 (Reuters) - Wall Street futures rose on

Wednesday after U.S. President Donald Trump extended the

ceasefire with Iran indefinitely, even as uncertainty remained

over whether Tehran and U.S. ally Israel would honor the truce.

At 4:37 a.m. ET, Dow e-minis rose 171 points, or

0.35%, S&P 500 E-minis gained 31 points, or 0.44%, and

Nasdaq 100 E-minis added 155.5 points, or 0.58%.

The bullish sentiment points to a market desperate for good

news, with investors clinging to the view that peak uncertainty

has passed, despite risks that inflation could flare up.

The S&P 500 and the Nasdaq Composite hit

record highs in recent days even though oil prices remain near

the $100-a-barrel mark.

"The peace process is looking wobbly again as some of the

difficult realities of the war come to the fore," said Kyle

Rodda, senior financial market analyst at Capital.com.

"The risk is (that) Iran's domestic political dynamics and

strategic tensions between the U.S. and Iran -- not to mention

Israel -- maintain an inertia towards escalation."

Trump said in a statement on social media the U.S. had

agreed to a ‌request by Pakistani mediators "to hold our Attack

on the Country of Iran until such time as their leaders and

representatives can come up with a unified proposal ... and

discussions are concluded, one way or the other."

Investors were also set to scrutinize a fresh batch of

earnings reports, with planemaker Boeing ( BA ) and medical

device maker Boston Scientific ( BSX ) among the companies

reporting results before market open.

Boeing ( BA ) shares rose 2.6% in premarket trading, while Boston

Scientific ( BSX ) was up 1.2%.

EV giant Tesla, chipmaker Texas Instruments ( TXN )

and Southwest Airlines ( LUV ) will report after market close.

Earnings so far have reassured investors about the health of

the U.S. consumer, the growth engine of the economy. S&P 500 EPS

estimates for 2026 and 2027 have risen by 4% since late January,

according to data from Goldman Sachs.

Adobe was 2.8% higher after it unveiled a share

repurchase program worth up to $25 billion.

Crypto-related stocks gained, with Coinbase Global ( COIN )

and Strategy up 4% and 5.6%, respectively.
