Insider Buying Stocks — Live SEC Form 4 Tracker
When an executive or director uses their own cash to buy company stock on the open market — code 'P' on SEC Form 4 — it's the single highest-confidence signal a public company is willing to send. Tapeline tracks every Form 4 filing across the live universe, surfaces the open-market buys (not option grants, not 10b5-1 sales), and ranks them by transaction value with the ticker's full score next to each row.
| Ticker | Insider | Shares | Price | Value | Filed |
|---|---|---|---|---|---|
| BRK.B | Director | 50,000 | $480.12 | $24.01M | 3 days ago |
| ORCL | CEO | 25,000 | $168.45 | $4.21M | 5 days ago |
| AMD | CFO | 10,000 | $142.30 | $1.42M | 1 week ago |
| INTC | Director | 75,000 | $22.18 | $1.66M | 1 week ago |
| DIS | Officer | 12,000 | $96.40 | $1.16M | 2 weeks ago |

How insider buying signals work
SEC Form 4 must be filed within two business days of any transaction by a director, officer, or 10%+ shareholder. The form discloses the transaction code, share count, price, and resulting ownership. Tapeline ingests every Form 4 daily via Finnhub, indexes by ticker, and surfaces the P-coded open-market buys separately from S (sales), A (grants), M (option exercises), G (gifts), and F (tax withholding).
Why open-market buys specifically: an executive exercising options or receiving a grant tells you nothing — that’s compensation, not conviction. An executive writing a personal cheque to buy company stock at the market price tells you they think the price is going up from here. That’s the signal this surface is built to isolate.
The full live feed lives at /app/holdings (Premium). Each row links through to the ticker page where you can see the Form 4 transaction in the context of the full 6-factor Tapeline score — trend, relative strength, fundamentals, smart money, macro, momentum.
Common questions
Is SEC Form 4 data really public?
+
Yes — Form 4 is a public filing required under Section 16(a) of the Securities Exchange Act. Every transaction by a corporate insider must be disclosed to the SEC within two business days and is searchable on SEC EDGAR. Tapeline indexes this public data — we don't have access to anything private.
Does insider buying actually predict returns?
+
The academic evidence is among the strongest of any single-signal study. Open-market insider buys (Form 4 code 'P') tend to precede above-average forward returns, particularly when the buyer is a CEO, CFO, or director with a sizeable position. The effect weakens for routine compensation transactions (option grants, 10b5-1 sells), which Tapeline filters out separately so the signal isn't diluted.
What's the difference between this and OpenInsider / Insider Monkey?
+
OpenInsider and Insider Monkey are excellent raw data sources. Tapeline joins the Form 4 feed to its 6-factor composite score for every traded ticker — so each insider buy comes with the trend / relative strength / fundamentals context for the underlying company, not just the transaction in isolation. The composite + the insider transaction together is a much sharper signal than either alone.
Can I get alerts when an insider buys a specific ticker?
+
Yes, on Premium. Add the ticker to your watchlist and create an alert rule for insider transactions on that symbol; you get an email or Telegram message the day the Form 4 hits EDGAR.
How often does the feed update?
+
Insider Form 4 filings are pulled daily from Finnhub's SEC indexer. The data lag from actual transaction to public availability is the SEC's own two-business-day window plus a few hours for indexing — typically you see new transactions within 24 hours of the filing.
What tier do I need?
+
Recent insider buys is a Premium feature ($39.99/mo billed annually, or $49.99/mo monthly). The 14-day Premium trial includes it. Premium adds Congressional trades and unlimited Telegram alerts on top of everything in Pro.
