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

The prices in this company's filings do not line up with what its shares actually cost, so the figures worked out from prices are not shown. The share counts are.

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 chart, in numbers

Flow	Shares
From holdings	46K
Granted	392K
Withheld for tax	230K
Planned sales (10b5-1)	165K
Discretionary sales	43K

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.

“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.

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
