Some stocks move before the headlines hit. If you want an edge, insider stock buying is one signal you can watch because insiders are putting their own money on the line.
According to Fintel, research on “high conviction” insider purchases found 12-month excess returns of 20.94%. That doesn’t guarantee results, but it helps explain why you’ll often see investors track insider buying, especially when purchases are large or clustered.
Now let’s walk through 10 stocks with heavy insider buying in the last month, and how you can use the signal without getting buried in raw data.
Key Takeaways
- Insider stock buying can help you spot confidence before the market fully reacts.
- The strongest insider buying signals are usually large, repeated, or clustered purchases.
- You’ll get better results by using insider buying to build your watchlist, then confirming with fundamentals and price action.
What Is Insider Stock Buying?
Insider stock buying occurs when company insiders, such as executives, directors, or major shareholders, purchase shares of their own company and publicly report the purchases.
Why should you care? Because insiders often have a better feel for:
- How business performance is trending right now
- What changes are happening internally
- What catalysts could be coming next
- Whether the market is undervaluing the company
Still, your best move is to treat insider buying as a research signal, not a guarantee. It’s a way to narrow your focus and decide what’s worth your time.
What Counts as “Heavy” Insider Buying?
If you’ve ever looked at insider filings, you already know the problem: there’s a lot of noise.
“Heavy” insider buying usually means you’re seeing one or more of these patterns:
- Big purchases in dollars or shares (not small, symbolic buys)
- Repeat buying over multiple transactions
- Cluster buying, where more than one insider buys around the same time
- Buying from a credible insider or major shareholder
These patterns matter because they’re the ones most likely to get noticed by other investors, too. And once investor attention builds, that’s often when price action starts to shift.
With that in mind, here are the names that stood out over the last month.
10 Stocks With Heavy Insider Buying in the Last 30 Days
Below are 10 stocks that showed notable insider stock buying activity in the last month. Use this list to build your watchlist and guide your research.
1) Immunovant (IMVT)
Immunovant reported major beneficial-owner buying, with widely reported purchases of around $350 million. When you see insider stock buying at this scale, it often puts a stock on your radar fast because the market views it as strong conviction.
2) Kymera Therapeutics (KYMR)
Kymera Therapeutics had heavy insider buying, widely reported at around $172 million. Large, high-profile buying like this can keep a stock in focus because investors assume insiders see value the market hasn’t fully priced in.
3) Under Armour (UA)
Under Armour saw major shareholder-related buying totaling approximately $67.5 million. In consumer brands, insider stock buying can signal confidence in valuation support, a turnaround plan, or improving execution.
4) Kenvue (KVUE)
Kenvue reported meaningful insider stock buying totaling around $55 million, tied to a notable director purchase. For you, the takeaway is simple: large buys like this tend to get attention because they’re easy to interpret as conviction.
5) Wave Life Sciences (WVE)
Wave Life Sciences reported a strategic holder buying totaling about $27.9 million. When large holders buy in size, you’ll often see more investor interest and potentially more volatility.
6) W.R. Berkley (WRB)
W.R. Berkley saw additional buying activity reported in the multi-million-dollar range. If you’re using insider buying as a signal, you’ll want to watch whether this buying continues, because repeat buying can strengthen the message.
7) Seven Hills Realty Trust (SEVN)
Seven Hills Realty Trust reported an insider purchase of approximately $17.4 million. In REITs and rate-sensitive names, heavy insider buying can be a helpful sign that insiders believe the valuation is attractive.
8) Navan (NAVN)
Navan showed notable cluster-style insider buying across multiple purchases reported in the multi-million-dollar range. Cluster buying matters to you because it suggests shared conviction across multiple insiders, not just one buyer.
9) Hycroft Mining (HYMC)
Hycroft Mining had reported beneficial-owner buying activity. In commodity-linked names, insider stock buying can attract attention quickly, but you’ll still want to weigh balance sheet strength and macro risk.
10) Kodiak Sciences (KOD)
Kodiak Sciences reported a major insider purchase of roughly $60 million (2,608,696 shares at $23.00). When you see insider stock buying at that size, it’s a clearer “conviction” signal than the small, symbolic buys that show up in most screeners.
Bottom line: The best way to use insider buying is to focus on the pattern: big buys, repeat buys, and cluster buying. If you build your watchlist around those signals, you’ll spend less time chasing noise and more time researching what matters.
How You Can Use Insider Buying Without Getting Burned
If you want insider stock buying to help you, don’t treat it as a one-time signal. Use this quick process:
- Watchlist first: Don’t rush. Insider buying is a clue, not a conclusion.
- Look for patterns: Repeat purchases and cluster buying matter more than a single purchase.
- Check fundamentals: Cash/debt, revenue/margins, guidance, and upcoming catalysts.
- Confirm with price action: Volume, trend shifts, or breakouts can validate the signal.
Once you understand the process, the next question is simple: how do you apply it consistently without spending hours digging through filings every day? That’s where most screeners fall short.
Why Choose Insider Trading Alerts Instead of Screeners?
If you’re using insider stock buying to find opportunities, the hard part isn’t getting the data. It’s knowing what’s worth your attention. Screeners can show you filings, filters, and dashboards, but they usually don’t tell you:

- Which trades are noise
- Which names are worth watching before the next market opens
So you end up doing the sorting yourself.
