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 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. 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. Scheduled: set up in advance under a Rule 10b5-1 trading plan. 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: the stock's move from the trade date to the latest close we hold (figures as of Oct 25, 2026), not the member's result. Not investment advice.

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.

Members of Congress reporting a position

2 members · estimate, as of Oct 20, 2026

2 members report a position (estimated). The largest estimated position is in the $15,001 - $50,000 band.

MemberParty, chamberEstimated positionShare of their portfolio
Robert BresnahanRepublican · House$15,001 - $50,0000.1%
Julia LetlowRepublican · House$1,001 - $15,0000.8%

Estimate, as of Oct 20, 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.

Regeneron Pharmaceuticals, Inc. 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 REGN trades disclosed?

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.
