Fundamentals · FY2027 Valuation

Standard valuation multiples from SEC-reported GAAP financials (trailing twelve months), each compared to the median for Industrials. We use reported GAAP, not forward or adjusted earnings, so our figures can sit higher than sites that do — especially for companies with falling profit. Relative context — not a target price or investment advice.

P/E
35.35
▲ pricier than Industrials (median 24.6)
how it's calculated
P/E = price ÷ earnings per share
$239.11 ÷ $6.76 = 35.35
Based on GAAP trailing-twelve-month financials (SEC filings) and the latest close. Other sites may show a different multiple when they use forward (projected) or non-GAAP adjusted figures instead of reported GAAP — for a company with volatile profit those can differ in either direction from the GAAP figure shown here.
P/B
21.48
▲ pricier than Industrials (median 4.4)
how it's calculated
P/B = price ÷ book value per share
$239.11 ÷ $11.13 = 21.48
Based on GAAP trailing-twelve-month financials (SEC filings) and the latest close. Other sites may show a different multiple when they use forward (projected) or non-GAAP adjusted figures instead of reported GAAP — for a company with volatile profit those can differ in either direction from the GAAP figure shown here.
EV/EBITDA
29.22
▲ pricier than Industrials (median 15.0)
how it's calculated
EV/EBITDA = (market cap + net debt) ÷ EBITDA — net cash lowers EV
($298.7B − $3.7B net cash) ÷ $10.1B = $295.0B ÷ $10.1B = 29.22
Based on GAAP trailing-twelve-month financials (SEC filings) and the latest close. Other sites may show a different multiple when they use forward (projected) or non-GAAP adjusted figures instead of reported GAAP — for a company with volatile profit those can differ in either direction from the GAAP figure shown here.

Two things to watch per trade: the disclosure lag (how many days passed before the trade was made public) and the price move in that window (how the stock moved during those non-public days). A sell followed by a price drop, or a buy followed by a rise, means well-timed trading — visible here in the open. Note: the Score measures how notable a trade is, not whether it made money — the price move is shown for context and isn't part of it.

Corporate insiders · SEC Form 4 Insider Activity

What the company's own officers and directors did in LRCX — open-market purchases and sales from SEC Form 4 filings (option exercises, grants and tax withholding are excluded). This is context for the congressional activity above, never a buy/sell signal, and the two datasets are kept separate on purpose. Does convergence mean anything? →

Insider open-market trades

Of the congressional trades in LRCX, 29 coincided with corporate insiders moving the same way within 60 days, and 22 with insiders moving the opposite way. This is co-occurrence only — whether it carries any edge is tested honestly on the convergence page.

Is it legal for members of Congress to trade LRCX?

Members of Congress may trade stocks but must disclose it under the STOCK Act. QuantCapitol tracks those public disclosures for transparency — nothing here is an accusation of wrongdoing or investment advice.

Where does this data come from?

Official US House Clerk and Senate electronic financial disclosures. Every trade links back to its original filing so you can verify it yourself.

About this data. Sourced from official House Clerk and Senate eFD financial disclosures (Senate via a maintained community mirror — see project documentation). Transaction amounts are reported as ranges, not exact figures. Interest scores, consensus labels, and backtested performance are proprietary analytical calculations based on public data and are not investment advice. Backtested performance is a hypothetical simulation, not actual portfolio performance.
