Why Isn’t the Market Down More on Higher Interest Rates?

The reason is not that the market is fine. The damage is hidden.

Why Isn’t the Market Down More on Higher Interest Rates?

The indexes are higher early Friday, with oil down and bonds a bit firmer. On Thursday, the market handled a surge in interest rates quite well. The 10-year hit a multi-year high near 5.2%, which is the biggest one-day jump since the Liberation Day tariff shock in April 2025. Investors could have easily panicked on this news but they did not.

Why is it different this time? A 10-year bond at levels not seen in nearly 20 years should be doing more damage than it is. The answer is that it is doing plenty of damage, just not where the indexes show it.

The Damage Is Severe, It Is Just Hidden

We do have a lot of stock market weakness. Breadth has been poor for weeks, and Thursday produced 400 new lows against 75 new highs. That is a direct function of the problems with higher rates. That is a market getting hurt and it is hitting interest rate sensitive groups like housing, small-caps, biotech, commercial real estate, and everything that depends on the cost of money.

What offsets it is a small group of big-cap AI names that refuse to react to interest rate worries. Alphabet (GOOGL), Meta Platforms (META), Apple (AAPL), Advanced Micro Devices (AMD), Dell (DELL), Eli Lilly (LLY), and Visa (V) have been strong enough to hold the indexes up while 400 stocks underneath them make new lows.

So the reason there is not a stronger negative reaction is not that the market is fine. It is that the averages are being carried by names that are immune to the interest rates that are crushing everything else.

Why the AI Names Are Immune

The key issue that the bears are ignoring is that the economy is genuinely strong but the strength is primarily AI-driven. Wednesday’s PMI was the strongest in years, with manufacturing posting its biggest monthly jump since 2022. That strength is exactly why yields are rising.

We have a hot economy and that makes the Fed’s job much harder. It is also why the AI names hold up. There is durable and substantial growth in AI and the group is not sensitive to higher interest rates like other less profitable sectors.

The AI companies are going to spend on the buildout regardless of what interest rates do. The returns they see are too large for a few points of borrowing cost to matter. So higher rates do not slow them, which means higher rates do not slow the biggest driver of the economy, which means the Fed has to push rates even higher to get any braking effect at all.

If AI refuses to slow down, the Fed is put in a position where it will have to crush everything in the economy that isn’t AI. The Fed doesn’t have the ability to target just the AI boom, so it has to break everything else to compensate.

That Is the 400 New Lows

That dynamic is what explains the 400 stocks making new lows. They are the product of the Fed’s fight against inflation. Housing rolled over as mortgage rates hit 7%. Small-caps and biotech, which live on borrowed money, are getting marked down hardest. Commercial real estate is squeezed. Meanwhile the mega-caps and the AI names sail through, because they are the one part of the economy the rate hikes cannot touch.

I’ve been writing about this two-tiered market action for a long time and this is the macroeconomic reason that is driving it. The same AI boom that holds the indexes up is forcing the Fed to cause destruction of everything beneath them. The robust economy and the 400 new lows are the same story told from opposite ends.

The Coiled Spring

Ironically, what could benefit the market more than anything else is the AI boom slowing down. If it does slow, and I wrote this week about how unstable the AI leadership actually is, the entire equation flips. The Fed can ease the rate pressure, and the 400 names being crushed right now get relief.

The thing weighing on the broader market is the same thing that, if it cracks, sets the broader market free. The 400 new lows are a coiled spring. They are being pushed down by a force that is not about their businesses, and when that force lets up, the snapback can be violent. That is why I keep a shopping list and keep patient. I am not trying to catch these while the Fed is still crushing them. I am getting ready for the moment the pressure is relieved.

My Game Plan

This is why I am maintaining my patient and selective strategy. I have cash ready, and I do not fight a market where the Fed is actively working to keep the broader economy down. The rallies in the indexes cannot be trusted. The tell is the bond market, and until yields stabilize, the pressure on the 400 stands.

What I am watching for is either a turn in bonds or a crack in the AI story, because those are the two things that would release the pressure on the broader market. Neither has happened yet. When one does, the shopping list I have been building through all this weakness is where I go to work.
