Hello everybody. Let’s talk about Friday.
On Friday, June 5, the Nasdaq — the American index that tracks the largest technology companies — fell 4.2%. Its worst day in over a year. The S&P 500 (the index of the 500 biggest American companies) dropped 2.6%, its sharpest single day since October. If you hold stocks, American technology in particular, Friday hurt.
Now here’s the part that should make you stop. The two events that “caused” the fall were both good news.
A few days earlier, Broadcom — one of the most important chip companies in the world — reported a record quarter. Its artificial-intelligence chip business more than doubled in a single year. Excellent by almost any measure. Then, on Friday morning, the U.S. jobs report landed: 172,000 new jobs in May, more than double what economists had expected. A strong, healthy labor market.
A record earnings report. A strong economy. And the market fell anyway, hard. How does that work?
Let me explain — because once you understand the mechanism, you’ll never read a market-crash headline the same way again.
Great Wasn’t Good Enough
Start with Broadcom. The quarter was excellent. So why did the stock fall sharply?
Because the market doesn’t pay for what a company did. It pays for what it expected the company to do. (We covered this in Letter #09, with the defense stocks — “buy the rumor, sell the news.”) Investors had been leaning forward in their seats, waiting for the CEO to promise that future sales would climb even faster than he’d already said. He didn’t. He delivered a great year — just not the spectacular one the crowd had already convinced itself was coming.
So a company that did almost everything right got punished. Not because it failed, but because “excellent” landed a step short of “miraculous.” When a stock is priced for a miracle, merely great is a letdown. This is the same AI gold rush we dug into in Letter #07 — the chip-makers selling shovels while everyone digs. The shovels are still flying off the shelves. The crowd had simply convinced itself they’d fly even faster.
When Good News Is Bad News
Now the jobs report. 172,000 new jobs, more than double the forecast, is a strong number. Normally, a strong economy is good for stocks. So why did it push them down?
Because for months, one of the things keeping the market calm was the hope that the Federal Reserve (the U.S. central bank) was about to start cutting interest rates. A jobs report this strong tells the Fed the economy doesn’t need the help — so there’s no reason to rush. The hope of a near-term rate cut, which a lot of investors had been quietly leaning on, slipped away. You could see it instantly in the bond market, where the interest the U.S. government pays to borrow money jumped — the market’s way of saying out loud, “no cut is coming.”
Take away that hope, on a day when the market was already hunting for a reason, and you have the second spark.
But Here’s the Real Story
Everything I just described is true. But it is not really why the market fell so hard in a single day. Those were the triggers. They were not the cause.
Here is the cause. The Nasdaq, and the chip stocks inside it especially, had been on a historic run. The main index of semiconductor stocks was up about 65% since the start of the year. Sixty-five percent — in five months. After a climb like that, a pullback isn’t a surprise. It’s overdue. The market was a rubber band stretched as far as it would go.
When a market is wound that tight, it doesn’t need a strong reason to snap back. It just needs a trigger — any trigger — that gives everyone permission to do what a lot of them were already itching to do: take their profits and step aside. Broadcom being “merely excellent,” and the jobs report quietly removing the hope of a rate cut, were never powerful enough on their own to do this much damage. They were the excuse, not the reason. The crowd was already inching toward the exit. Someone just had to say the word.
And this is where the part most people never talk about comes in.
Why Everyone Sells at the Exact Same Second
Picture a crowded theater. Someone smells smoke. If people filed out one at a time, calmly, no one would get hurt. But that is not what happens. The instant a few people bolt for the door, everyone bolts — and the door, built for a steady flow, can’t handle a stampede.
Now replace the people with computers.
Today, most of the trading on the U.S. stock market — roughly two-thirds of it — is done not by people, but by automated programs. And a large share of those programs are built to follow one simple instruction: the moment prices start falling, sell, and keep selling for as long as they keep falling. These programs don’t read earnings reports. They have no view on Broadcom. They don’t even care why the price is dropping. They follow the direction of the price, and nothing else.
So here is what happens. The triggers hit. A few large players start selling. Prices tick down. The automated programs see the move and sell too — which pushes prices lower — which trips the next wave of programs into selling — and on it goes, each wave feeding the next. In my view, this is the single most important change in how markets work that most investors still haven’t absorbed: the reason a market can fall this far in hours instead of weeks is that the machines all run for the same door at the same second, because they are all obeying the same rule.
The trigger was the size of a person. The stampede was the size of a machine.
The Clue Hiding in Plain Sight
Want proof this was profit-taking, and not the economy breaking? Look at the other index.
While the Nasdaq fell 4.2%, the Dow Jones — which holds far fewer high-flying tech names and many more “old economy” companies — fell only 1.3%. If investors genuinely believed something was breaking, everything would have dropped hard together. It didn’t. The money didn’t flee the market. It rotated — out of the most stretched, most expensive technology and chip stocks, and into the companies that hadn’t run up nearly as much. That is not fear about the economy. That is a crowd quietly cashing in its biggest winners and moving the chips to a calmer table.
So — Healthy Pause, or the Start of Something Worse?
I’ll give you my answer plainly, because you deserve one: this was a healthy pause, not the beginning of a collapse.
Here’s why I’m comfortable saying it. Nothing about the real economy, or the real companies, got worse on Friday. Broadcom’s business didn’t shrink — it grew. The jobs report was strong, not weak. The thing that fell wasn’t the worth of these companies; it was the price a very excited crowd had been willing to pay for them. A market that drops because the economy is breaking looks like everything falling together. A market that drops because one over-loved corner simply got too expensive looks exactly like Friday: the stretched part snaps back, and the rest barely flinches. This was the second kind.
That doesn’t mean the ride is over. A stretched rubber band can snap back a long way before it settles, and the machines can keep the selling going for a while no matter what the companies are actually worth. But a pause that lets an overheated market catch its breath is a healthy thing, not a frightening one.
What This Means for Your Pocket
If you hold a pension fund or a savings plan: you almost certainly own a slice of these American tech and chip companies, even if you’ve never bought a single share yourself. Friday touched your savings, quietly. This is not a reason to do anything — it’s a reason to understand that “the market” inside your pension is, to a real degree, a bet on a handful of technology giants.
If you hold technology or chip stocks directly: ask the question we always come back to — did the story change, or just the price? On Friday, only the price changed. The businesses behind these stocks are doing exactly what they were doing on Thursday. That is a very different thing from a company in trouble.
If you’ve been waiting to buy: a pullback after a run this big is exactly the kind of moment that tempts people in. It may well be an opportunity. But check each company on its own, don’t guess — a stretched market can fall further before it steadies, and no one rings a bell at the bottom.
And for all of us: Friday was a reminder that the size of a market move and the size of its real cause are often completely unrelated. The market didn’t fall because the world changed. It fell because a very stretched market found an excuse, and a market run mostly by machines turned that small excuse into a stampede. Understand that, and the next frightening headline will read very differently to you than it does to everyone else.
We shall see.
See you in next week’s letter, or during the week — if I can’t help myself until then...
