How to Interpret $BSX Trades
Not every insider transaction in BOSTON SCIENTIFIC CORP is a signal for immediate action. Professional investors look for "cluster buying"—when multiple executives simultaneously purchase $BSX 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 BSX
Insider activity data for BOSTON SCIENTIFIC CORP is streamed in real-time directly from the SEC EDGAR system.

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