CNBC Daily Open: Keeping a cool head paid off for investors

• S&P and Nasdaq touch fresh highs.
• White House claims Canada 'caves' on trade.
• China's June factory activity unexpectedly expands.
• Elon Musk calls Trump bill “DEBT SLAVERY.”'
• Some companies are expected to benefit from higher NATO defense spending.

What a first half of the year it has been.

In the first six months, the world saw a (not so) new U.S. president in the Oval Office, said president upend the global trade landscape, and a president in South Korea removed from office.

Conflicts also broke out between India and Pakistan, as well as Israel and Iran (along with a U.S. airstrike thrown into the mix.)

Chinese AI startup DeepSeek made its debut, stealing ChatGPT's thunder for a while, and elections took place around the world, including in Germany, Australia, and even right here in sunny Singapore.

We might just have to call Billy Joel and get him to write a whole new version of “We Didn't Start the Fire.”

Despite such a rollercoaster ride so far, market investors, in response to most developments, seem to have adopted the U.K.'s mantra as it prepared for war in 1939: Keep calm and carry on.

If we take a longer-term view, markets have delivered a respectable performance despite a volatile first half. Just a few stats: the S&P 500 and Nasdaq Composite closed at fresh all-time highs Monday and are up about 5% year to date.

In Europe, the Stoxx 600 is up 6.7%, and in Asia, most major markets are in positive territory, with Hong Kong and South Korea posting a whopping 20% gain year to date.

Keep calm and carry on into the second half of the year, investors.

China's June factory activity unexpectedly expands. The Caixin/S&P Global manufacturing purchasing managers' index came in at 50.4, higher than the Reuters estimate of 49. It also diverged from China's official PMI report, which samples more companies, mostly in upstream sectors.

Elon Musk calls Trump bill “DEBT SLAVERY.” The Tesla and SpaceX CEO is doubling down on his criticisms to kill Trump's signature megabill. Musk also called for a “new political party,” and vowed that any fiscal conservative who votes for the bill will “lose their primary next year.”
