How to Interpret $KEX Trades
Not every insider transaction in KIRBY CORP is a signal for immediate action. Professional investors look for "cluster buying"—when multiple executives simultaneously purchase $KEX shares on the open market. It is crucial to distinguish between scheduled sales (under Rule 10b5-1) and voluntary increases in ownership, which demonstrate management’s true conviction that the stock is undervalued.

TRADE DATE: The actual day the insider executed the purchase or sale in the market.
