A head-in-the sand approach often works well, until you have to eventually confront the problem. The stock market hasn't reached that point yet, it's still ignoring the bond market and powering toward record highs. That's either very brave or very foolish.

The technology-heavy Nasdaq Composite was set to rise again Tuesday after reaching an all-time closing high Monday, and the S&P 500 is on track to test its record, too. That's all while Treasury yields have risen to decadeslong highs ahead of another big test today.

The megacap tech stocks have been doing the heavy lifting. Nvidia closed at a record high Monday and suddenly isn't far off reaching a staggering $6 trillion market cap after rising 22% in just three months.

But for every Nvidia, there's a Nike. The sportswear giant got another downgrade and the stock was on track for a fresh 13-year low. The turnaround has been a challenge to say the least.

Another tough task awaits Paramount Skydance when it closes its ambitious $110 billion acquisition of Warner Bros. later on Tuesday.

Again, the line between bravery and foolishness can be very thin indeed.

💻 Why Intel doesn't need Elon Musk as much as we think

It was seemingly bad news for Intel when Elon Musk, CEO of SpaceX and Tesla, signaled that Taiwan Semiconductor Manufacturing was exploring work with his chip venture Terafab.

🎥 Paramount will be risky after Warner Bros. deal

Paramount plans to change its name to Skydance today when its merger with Warner Bros. Discovery is completed.

🛒 Why Wall Street might be wrong to hate consumer stocks
