Nasdaq Hits Record High: The Narrow AI Rally Nobody Wants to Talk About

The S&P 500 closed at 7,773.95 on Monday, the Nasdaq at 27,477, both sitting at fresh all-time highs. The VIX dropped to 15.31 last Thursday, a 6.59% single-day plunge, and retail is feeling great about life. War in the Middle East? Shrug. French debt crisis? What's that? Ten-year yields at 5.28%? Totally fine, apparently.

Here's the catch, and RBC's Amy Wu Silverman said it plainly on CNBC: market breadth is extremely narrow, with roughly 73% of stocks underperforming the index. Mega-cap tech is doing the heavy lifting while rate-sensitive sectors quietly suffocate. Bloomberg's David Savage noted that Nvidia, Broadcom, and Microsoft drove nearly 50% of S&P returns on Monday alone. That's not a bull market, that's a relay race where three people are carrying everyone else piggyback.

The AI trade is real, but it's getting concentrated fast. Anthropic's annualized revenue reportedly surged from $9 billion to over $70 billion in a single year. $400 billion in US venture capital was deployed in just the first half of 2026, with roughly half going to OpenAI and Anthropic alone. Meanwhile, Microchip Technology ($MCHP) is flying under the radar with 51% forward EPS growth and a PEG ratio of 0.49x versus the sector's 1.3x. Not every AI winner has a trillion-dollar valuation.

The bear case is sitting right there in the bond market. The 10-year Treasury yield has been sticky around 5.24% to 5.29% all week, and Ray Dalio is out warning of a US debt crisis within three years. Meanwhile France's OAT-Bund spread is at its widest since the Eurozone debt crisis, the euro is down 3.5% against the dollar since September, and Japan's 30-year bond just hit an all-time high yield. Global sovereign debt stress is not contained to one country, it's spreading like a bad group chat.

Brian Belski of Humilis remains unapologetically bullish, arguing earnings growth justifies elevated rates and that companies hold massive cash with low debt-to-equity ratios. He sees 8 to 10 more years left in this secular bull run. He's been right since November 2008, which is the most annoying kind of right to be.

The market is essentially telling you it believes in AI enough to look past a war, a debt spiral, and yields that would have tanked equities two years ago. Maybe it's right. Or maybe the flood insurance analogy Wu Silverman used is the one to remember: when tail risk goes from 0.5% to 20%, the price of protection should change, and right now it hasn't.
