Actual against the consensus estimate at the time. A flag marks a beat or a miss of more than 1.5% either way; inside that band the quarter is in line. A flag marked GAAP compares a GAAP figure the company reported with an adjusted consensus, two different measures, so a one-time gain or charge can move it either way. A flag reads n/a only when a number is missing. Quarterly EPS is the figure set against the consensus, usually adjusted, so the quarters need not add up to the 12-month net income per share above. An estimate is a forecast made by analysts, not a company target.

A 13F reports long US equity positions and is filed within 45 days of the quarter end, so these are positions as they stood on Jun 30, 2026. New: not in this holder's prior 13F as reported; a change of filer ID can also show as new. For a manager's whole book see the fund directory. What a 13F covers and leaves out is explained in our guide to Form 13F.

One row is one filing, newest filing first. A filing that reported its trade in several tranches is summed, priced at the weighted average, and marked with its line count. The delay counts business days from the trade to the filing, the unit of Form 4's two business day deadline: weekends and federal holidays are skipped. How the filing itself works is explained in our guide to Form 4.

Since the trade is an estimate, set beside the S&P 500 over the same window, with the gap between the two in percentage points. The filing carries a band, not a fill, and a sale keeps the stock's sign, so a positive figure after a sale means the stock kept rising after it. An option row carries the underlying stock's move. A row marked n/a is one we hold no figure for.

A delay above 45 days is the gap between the dates on the report; we mark a filing late only after checking it.

Every Congress trade in COST, filterable by party, chamber, type and account.

A further member reports a position estimated under $1,000; that member is not listed.

Estimate, as of Oct 19, 2026. Each position is modelled from the member's disclosed transactions and annual filings: the midpoint of each disclosed band, moved with the stock's price since the trade. It is a rough estimate of a reported position, not a figure from a filing, which is why it is shown as a band. Share of portfolio sets that estimate against the member's whole estimated public-stock portfolio.

Questions

Are insiders buying or selling COST?

Across the 14 most recent open-market filings shown here, 0 were purchases and 14 were sales.

Which members of Congress have traded COST?

Rick W. Allen, Ro Khanna, Richard McCormick, Alan Armstrong, Dan Newhouse, Gilbert Ray Cisneros, Jr. and others disclosed COST transactions in the filings shown here.

Which members of Congress hold COST?

17 members of Congress report a position of $1,000 or more in COST in the estimate we hold as of Oct 19, 2026. The two largest estimated positions belong to Kevin Hern and Rick W. Allen; Gilbert Ray Cisneros, Jr. holds one of the next largest, in the $100,001 - $250,000 band. The estimate is built from disclosed transactions and annual filings, so it is shown as a band rather than a figure from a filing.

Is COST in the S&P 500 or the Nasdaq 100?

Costco Wholesale Corporation is a current member of the S&P 500 and Nasdaq 100, per the membership list we hold as of Oct 26, 2026. Current members of either index get a page here whatever their filing history.

How quickly are COST trades disclosed?

Insider filings on this page reached the public a median of 1 business day after the transaction (weekends and federal holidays skipped), against the two business days Form 4 allows. Congressional disclosures took a median of 23 days, against the 45 the STOCK Act allows.

How to read a Form 4

A DECISION THE INSIDER MADE

POpen-market purchase. Bought with their own money at the market price.
SOpen-market sale. Sold on the market. A sale marked scheduled was set up in advance under a Rule 10b5-1 plan, often months before.

COMPENSATION PLUMBING

AStock award. Granted as pay, not bought.
MOption exercise. Converting options already held into shares.
FTax withholding. Shares handed back to the company to pay the tax on a grant.
GGift. Given away, with no money changing hands.

Congress rows disclose a value range rather than an exact amount, and the STOCK Act allows up to 45 days to report. Full sourcing and the limits of this data are on the methodology page. A filing is a record of a transaction, not a signal, and nothing here is investment advice.
