SNDK Insider Activity
SEC Form 4 filings, signal scores, and insider role breakdown — updated as EDGAR publishes
Recent insider trading activity for SNDK. The table below shows the latest reported SEC Form 4 transactions from officers, directors, and 10% owners. Each row includes the transaction type, share count, price, and our proprietary signal score that highlights potentially significant activity. Curious how the scores are calculated? Read our methodology.
Insiders generally have up to two business days after a transaction to file Form 4. The Transaction Date is when the trade occurred; the Filed date is when the filing became available. DisclosureSignals alerts are notices about newly available public filings — the underlying transaction may have occurred earlier. Scores measure transaction characteristics, not expected returns.
