What to check in insider filings
- Open-market purchases — CEO/CFO buying with personal cash is the strongest insider signal.
- Cluster buying — multiple insiders buying within days of each other is stronger than one.
- Option exercises vs open-market buys — only open-market purchases with personal cash count.
- Rule 10b5-1 plans — pre-scheduled sales are noise; discretionary sales are signal.

What does insider selling at Amgen mean?
Insider selling has many causes (taxes, diversification, estate planning) and is weak as a standalone signal. What matters more: is the CEO/CFO buying with their own money? Are multiple insiders buying simultaneously? Clusters of open-market buys are the stronger signal.
Should I follow insider trades on AMGN?
Use insider activity as one input, not the thesis. The Balance Labs workflow checks insider behaviour as a supporting data point within the broader quality and valuation assessment — never as a standalone buy/sell reason.
