How to Interpret $AMAG Trades
Not every insider transaction in AMAG is a signal for immediate action. Professional investors look for "cluster buying"—when multiple executives simultaneously purchase $AMAG 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 AMAG
Insider activity data for AMAG 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 $AMAG, allowing you to follow the capital of those with the most intimate knowledge of the company.

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