8 trades Recent Congressional Trades
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 DLB — 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 DLB, 2 coincided with corporate insiders moving the same way within 60 days, and 2 with insiders moving the opposite way. This is co-occurrence only — whether it carries any edge is tested honestly on the convergence page.
