NEW YORK, June 30 (Reuters) - Tech stocks boosted Wall

Street as investors prepared to close the book on a month of

losses for the S&P 500 and the Nasdaq, but the strongest

quarterly percentage gains for all three major U.S. stock

indexes in years.

I will go into more detail on today's market moves below. If

you have more time to read, here are a few articles I recommend

to help you make sense of what happened in markets today.

1. U.S. Supreme Court upholds birthright citizenship

2. U.S. Supreme Court strikes down curbs on coordinated

campaign spending

3. U.S. consumer confidence edges up in June, but job market

perceptions sour

4. Britain says it could intervene in Paramount Skydance

Corp's proposed takeover of Warner Bros Discovery

5. German inflation cooled June and core price growth held

steady, easing concerns of war-related price pressures

6. ECB is considering doubling the proportion of cash

Today's Key Market Moves

* STOCKS: U.S. S&P 500, Nasdaq; Europe's

STOXX 600 all notch biggest quarterly percentage gains

in years, powered by AI strength

* SECTORS/SHARES: Chips lead, with SanDisk ( SNDK ),

AMD, Marvell ( MRVL ) and Intel ( INTC ) up between 6.0%

and 10.9%

* FX: Dollar pushes higher, yen slides to

40-year low

* BONDS: U.S. Treasury yields rise, but benchmark 10-year

yield set for monthly drop

Today's Talking Points

* AI spending, earnings, Fed outlook primed to lead stocks in

the second half of 2026

Stocks have had a good six-month run. But in order to keep

the rally going, markets will face a gauntlet of tests,

including the sustainability of AI spending, high earnings

expectations and shifting interest rate outlooks under Kevin

Warsh's chairmanship of the U.S. Federal Reserve.

* Uncertainty clouds path forward for U.S.-Iran peace talks as

U.S. envoys arrive in Doha

U.S. President Donald Trump's son-in-law Jared Kushner and

envoy Steve Witkoff arrived in Doha on Tuesday after airstrikes

over the weekend tested the June 17 interim accord between the

United States and Iran. No high-level meeting with Iran is on

the docket, but technical issues, including matters of regional

security, are on the table, issues that could be elevated to a

senior level, according to Qatar's Foreign Ministry

spokesperson.

* Trump to announce exit from North American trade pact

President Trump is expected to announce on Wednesday that

the United States will not extend the U.S.-Mexico-Canada

Agreement on trade, starting a decade-long clock to wind down

the 32-year-old North American free trade zone as the three

nations continue to hash out proposed changes.

The declaration will kick off a six-year review session,

part of a "sunset clause" negotiated during Trump's first

presidential term. However, it will do little to alter

contentious negotiations over the pact's future.

What could move markets tomorrow?
