How to Interpret $MMM Trades
Not every insider transaction in 3M CO is a signal for immediate action. Professional investors look for "cluster buying"—when multiple executives simultaneously purchase $MMM 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 MMM
Insider activity data for 3M CO is streamed in real-time directly from the SEC EDGAR system. We analyze raw Form 4 filings, filtering out technical adjustments and complex derivative transactions. This provides a transparent view of how ownership structure is evolving in $MMM, allowing you to follow the capital of those with the most intimate knowledge of the company.
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.
OWNED AFTER: The total number of shares held by the insider following the transaction. This highlights the insider's remaining conviction in the company.
CHANGE %: The percentage increase or decrease of the insider's total position. Large percentage changes often carry more weight than the dollar amount alone.
TRADE TYPES DEFINITIONS
BUY: An open market purchase. Typically indicates an insider's belief that the stock is undervalued or poised for growth.
