No open-market insider trades for KNF (Knife River Corp) in the last 365 days.

Why this page may be quiet. Tracefour displays Form 4 open-market purchases (P) and sales (S): the two transaction codes that signal directional conviction. Restricted stock grants, option exercises, gifts, and tax-withholding sales are filed but intentionally not shown: they're disclosure mechanics, not buy/sell decisions.

Many large-cap executives trade through pre-scheduled 10b5-1 plans set months in advance and batch-disclosed each quarter, so the latest filing on EDGAR for a mega-cap can be weeks old without any insider actually choosing to trade in that window.
