Round-trip watch Still on the books
Members who disclosed buying LRCX and have not disclosed selling, versus their own entry (the most recent disclosed buy). "Open" means no disclosed sale — never "still holds" — and the % is unrealised, on paper. Not investment advice.

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.

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? →
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.
