When the people running the company start selling, you should pay attention. In the first half of 2026, US corporate insiders sold $77.6 billion worth of stock — up 20% from the same period last year.
What's Happening
Insiders are the people who know a company best: CEOs, CFOs, founders. They see the numbers before anyone else. They know if the next quarter will disappoint. They know if competition is heating up. And that's why they're required to report their trades to the SEC — so everyday investors can see what the people with the best information are doing with their own money.
The number is near-record territory. For context: In H1 2025, insiders sold $64.7 billion. The last time we saw selling at this pace was early 2021 — right before the tech bubble burst and many stocks lost 40, 50, even 70% of their value.
What's especially striking: Tech insiders are selling aggressively. At three major US tech firms, CEOs sold over $200 million worth of stock in the past two weeks alone. The data shows movement across established Big Tech names as well as younger, high-flying software companies.
Why It Matters to You
Imagine you're the CEO of a company. You know the next quarter will be weaker than expected. Or that a competitor just launched a better product. Or that costs are spiraling. Do you sell your own shares — or do you buy more?
Exactly. Insider selling isn't an alarm bell when it's isolated (many CEOs sell regularly to buy a house or pay taxes). But when everyone sells at once, and the volume is 20% higher than last year, that's a warning.
For you, this means: If you're thinking about jumping into high-valuation tech stocks right now — maybe wait a few weeks. The people with the best information are pulling their money out. That doesn't guarantee a crash. But it does mean the people who know the most are being cautious.
And if you're already invested? Don't panic. But review your portfolio: Are you too concentrated in individual tech names? Do you have cash on hand in case stocks drop 10-15%? Are you diversified?
How the Pros Are Reacting
Large asset managers watch these numbers closely — and they don't make panicked moves, but they adjust their positions. Some are trimming tech exposure and rotating into more defensive sectors: healthcare, consumer staples, utilities. Others are building cash positions to buy the dip when it comes.
That's the difference between you and an experienced investor: The pro doesn't sell everything in a panic. They ask if their risk allocation still makes sense. And if too much is in one corner — they rebalance.
First Steps for Beginners
If you're just starting out with investing, this news is a lesson:
-
Insider data is public. In the US, you can find it on the SEC website (Edgar system) or platforms like QuiverQuant, GuruFocus, Barchart. In Germany, check BaFin filings. Look before you buy.
-
One sale isn't a verdict. But many sales at once are a signal. Like a friend telling you "I think the party's almost over."
-
Diversification protects you. If you're only in tech, you'll feel this twice as hard. If you're spread across a world ETF and different sectors, you'll sleep better.
-
Cash is a position. Money in a savings account isn't "wasted" — it's ammunition for the next pullback.
I know the feeling when everyone's buying and you're scared of missing out. I was there in 2000 — bought the Telekom stock at 100 euros, everyone was buying, me too. It fell to 8 euros. If I'd looked at the insider sales back then (they were there), I would've saved myself a lot of tuition money.
Stay calm. Stay the course.
