An Inside Look at Recent Insider Trades in U.S. Stocks
Here’s a clear rundown of the latest notable insider buying and selling in U.S. stocks. These moves don’t tell the whole story on their own, but they can hint at how people closest to a business feel about its near-term prospects and longer-term path.
Where Insiders Have Been Buying
Abdiel Capital entities added to their position in Appian Corp (NASDAQ: APPN) over just a few days, lifting their stake meaningfully. In total, they invested about $2.08 million, purchasing shares between $29.98 and $31.31. The most active day came at the end of the reporting period, when they picked up more than 22,000 shares at an average price of $30.22. Quick, steady buying like this often signals conviction—even if it’s just one piece of the puzzle.
ProFrac Holding Corp (NASDAQ: PFHC) also drew attention. THRC Holdings and its affiliates acquired 381,359 shares of Class A common stock across two transactions—one on September 5 and another on September 6—at average prices of $6.20 and $6.21. All in, the purchases topped $2.36 million. Two back-to-back buys at nearly the same price suggest a deliberate approach to building exposure.
At Black Stone Minerals, L.P. (NYSE: BSM), CEO and President Thomas L. Carter Jr. bought 100,000 common units on September 6 at an average price of $14.118. That’s an outlay nearing $1.41 million, and it meaningfully increased his holdings. When senior leadership adds personally, it can be read as a show of alignment with unitholders.
Golub Capital BDC, Inc. (NASDAQ: GBDC) saw two top executives—both named Golub—each purchase 40,000 shares at prices between $14.78 and $14.91. Each transaction came to roughly $593,800. Parallel buys like these can reflect internal confidence, though context still matters.
Where Insiders Have Been Selling
On the other side of the ledger, Michael Cannon-Brookes, CEO of Atlassian Corporation (NASDAQ: TEAM), sold more than $1.28 million of Class A Common Stock on September 6. The sales were executed between $159.51 and $165.13 under a planned trading strategy. That detail matters: planned programs can reduce the guesswork around timing.
Sotera Health Co (NASDAQ: SHC) saw a large block sale by Warburg Pincus & Co., which sold 15 million shares at $15.03 each—about $225.45 million in total. Even after the transaction, Warburg Pincus retained an extensive position, with approximately 73,822,952 shares remaining. Large holders often rebalance without abandoning their core stake.
Kellanova (NYSE: K) made headlines when the Kellogg W K Foundation Trust sold 114,583 shares on September 9 at roughly $80.25 apiece, totaling around $9.2 million. Following the sale, the Trust held 50,482,855 shares. One sale can be meaningful, but holdings of that size can accommodate routine adjustments.
Executives at NESCO Holdings LP sold 2,354,109 shares of Custom Truck One Source, Inc. (NYSE: CTOS) at an average price of $3.42, generating proceeds near $8 million. Moves like this may reflect portfolio management, profit-taking, or simply timing needs tied to broader plans.
How to Read These Moves
Insider activity can sharpen your view of a company’s trajectory, but it’s not a stand-alone signal. Buying can reflect optimism—or just a long-term accumulation plan. Selling can signal caution—or equally, diversification and liquidity needs. The “why” matters as much as the “what.”
The practical way to use this information is to fold it into a broader framework: fundamentals, valuation, cash flow, competitive position, and, if you track it, technical trends. A single transaction won’t tell you everything; a pattern, paired with a thoughtful research process, can help you decide what deserves a closer look.
Frequently Asked Questions
What exactly counts as an insider trade?
It’s the purchase or sale of a company’s stock by people with close ties to the company—often executives, directors, or major shareholders. These trades are reported so investors can see what informed insiders are doing.
Why might an insider buy or sell?
Plenty of reasons: portfolio diversification, taxes, personal cash needs, compensation-related timing, or a view on the company’s prospects. A single trade doesn’t always equal a bullish or bearish call.
How should I interpret large buys or sells?
Start with size, timing, and repetition. Multiple purchases in a tight window can suggest conviction. Large or repeated sales can mean repositioning. Context—role of the insider, remaining holdings, and prior activity—helps.
Where can I follow insider activity?
You can track it through regulatory disclosures, stock exchange announcements, and coverage from financial news platforms that summarize recent filings and transactions.
Should I trade based only on insider moves?
No. Treat insider trades as one input among many. Combine them with your own analysis of the business, its financials, and market conditions before making any decision.
