Not every insider transaction in ECOLAB INC. is a signal for immediate action. Professional investors look for "cluster buying"—when multiple executives simultaneously purchase $ECL 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.
Data Source & Accuracy for ECL

UNDERSTANDING THE DATA
FILING DATE: The date and time when the transaction was reported to the SEC. This is when the public first receives the information.
TRADE DATE: The actual day the insider executed the purchase or sale in the market.
INDUSTRY: The specific market sector the company operates in. Useful for identifying broader institutional capital flows across sectors.
