Insider trading
What directors, officers and big shareholders are doing with their own company's stock. They must report trades to the SEC on Form 4 within two business days. From SEC EDGAR; latest filing in our data Oct 14, 2026.
The last 30 days
Form 4 filings from Sep 14, 2026 to Oct 14, 2026. The last two weeks are thinner than usual (22 trades a day against 156 before), because recent filings are still being read; expect those numbers to rise.

Insiders sell far more than they buy: most sales are routine (pay, taxes, planned selling). Purchases are rarer and usually tell you more, since an insider who buys is putting their own money on the stock. For how insiders' trades have actually performed, see insider performance on otrecord.news.

Last 90 days, ranked by dollars bought.
What the transaction codes mean
Every line on a Form 4 carries a one-letter code. This page counts only P and S, the trades where an insider chose to buy or sell.
| Code | What it is | What it tells you |
|---|---|---|
| P | Open-market or private purchase | The insider bought shares with their own money. The clearest signal there is. |
| S | Open-market or private sale | The insider sold shares. Often planned in advance (a 10b5-1 plan), for taxes or to diversify. |
| A | Grant or award | Shares or options the company gave as pay. No money changed hands. |
| M | Option exercise | The insider turned options into shares, usually at a set price. |
| F | Shares withheld for tax | Shares the company kept back to pay tax on vesting stock. Not a sale decision. |
| G | Gift | Shares given away, often to family or charity. |
| D | Sold back to the company | Shares returned to the issuer, for example in a buyback. |
| C | Conversion | A derivative (such as preferred stock) converted into common shares. |
| X | In-the-money option exercise | An exercise of an option that was worth more than its strike price. |
| J | Other | Another kind of acquisition or disposal, explained in the filing's footnotes. |
