New to this? How to read this page
  1. Insiders are the people who run the company: officers, directors and owners of 10% or more. They must report a trade on Form 4 within two business days.
  2. A purchase on the open market is the strongest sign: the insider spent their own money.
  3. A sale under a trading plan (Rule 10b5-1) says little: its dates were fixed months before. Sales outside a plan say more, but insiders sell for many reasons, such as taxes or a house.
  4. Grants, option exercises and shares held back for tax are left out.
  5. What is a Form 4? · Form 4 codes

What kind of trades

Insiders only sold: 53 sales worth $126M, and 28 of them were under plans set months before, which say little.

Every Form 4 line of the last twelve months, counted by kind. The grades come from the filing itself: whether the insider paid cash, whether a plan set the date, whether pay was taken in stock by choice.

Insider trades on the share price

last twelve months

50 marks over twelve months, each in its grade: solid for the stronger signs, hollow or grey for the ones that say little.

The blue line is the daily close over twelve months. Each mark is one insider's trades on one day, on that day's price, sized by dollar value. Solid marks are the stronger signs; hollow and grey marks say little. Hover or tap a mark for who, how much and why.

Trades worth a closer look

A purchase stands out when two or more of these hold: a senior insider, several insiders buying within 90 days, a fall of 10% or more in the three months before, or over $1 million. A sale outside a plan is judged the same way. These are the Feed's rules.

Who traded

dollars, twelve months

10 insiders traded. The most: Chang Hung-Lun (Fred), sale outside a plan $19.5M; sale under a plan $6.9M.

One row per insider, sold to the left and bought to the right, split by grade: the paler part of a bar is the part that says little.

How it compares

every company on the site

Open-market sales, twelve months

Open-market purchases, twelve months

    The bar ranks every company on the site from the lowest on the left to the highest on the right, in three equal thirds; the small figures under it are the values where each third starts, and the black tick is the middle company. The orange dot is this company; the grey ticks are the other companies in its industry (hover or tap for names). A hatched block is companies tied at none.
