What the executives and directors of Booking actually did with their own shares, decoded from their SEC Form 4 filings. Each figure says the stretch of time it covers.

The tape: three years of insider trades

Every marker sits at the price reported on the Form 4. The line is the monthly median of all prices insiders reported, so the chart needs no market feed; the grey strip is the routine flow (grants, vestings, tax withholding and gifts) that a headline gets wrong by counting it as selling. The share count changed 23-for-1 on Apr 15, 2026, so prices and share counts reported before then are restated to today's basis here; otherwise the tape would show a step the shares never took.

Where the shares went, last 12 months

Every Form 4 movement decomposed: what flowed in (grants, vested equity, purchases) and what flowed out (tax withholding, plan sales, discretionary sales, gifts). Counted in shares, because grants carry no price. The share count changed 23-for-1 on Apr 15, 2026, so share counts reported before then are restated to today's basis here.

Flow	Shares
Granted	660K
Withheld for tax	329K
Planned sales (10b5-1)	300K
Discretionary sales	4,600
Gifts	1,200

Skin in the game

Directly held shares as reported after each trade, indexed to 100 at the start of the window, up to five years back. Direct holdings only: trust and family-entity positions are per-entity in the filings and do not sum honestly, so this chart refuses to guess. The steps are the trades. The share count changed 23-for-1 on Apr 15, 2026, so share counts reported before then are restated to today's basis here.

“Since trade” compares with the latest insider-implied price, not a market quote: these pages are built from filings alone. A role here is the one on that day's Form 4, so somebody promoted since appears under both titles. The share count changed 23-for-1 on Apr 15, 2026. This table prints prices and share counts as they were filed, on the basis of the day, while the charts above are on today's; “Since trade” puts the filed price on today's basis first, which is why it does not divide into the price beside it.

Filing hygiene

How to read this

A Form 4 transaction code decides everything. P is an open-market purchase and S an open-market sale; those two are the only codes where an insider chose to trade. A is a grant, M an option exercise or vesting, F shares withheld to cover tax, G a gift. Most “insiders dumped billions” headlines are code F and M mechanics.

Sales flagged 10b5-1 run on a plan the insider adopted in advance; since 2023 every Form 4 carries that flag. Buys have historically predicted returns, sales mostly have not, and this page states filings, not advice.

Every number on this page comes from Forms 3, 4 and 5 filed with the SEC. The insider export runs on its own schedule, so it can be a few days behind the rest of the site; the date below says how far it goes. Browse the source filings on SEC EDGAR. Data through Sep 18, 2026
