What insider trading data covers for AMKR
Amkor Technology, Inc. (CIK 1047127) reports Section 16 insider transactions on Form 4 within two business days. Each filing carries the transaction date, transaction code (P for open-market purchase, S for sale, M for option exercise, F for tax withholding), shares, price, and post-transaction holdings. Optional footnotes disclose Rule 10b5-1 plan references and indirect ownership relationships.
How to interpret AMKR insider activity
Treat each filing line through three filters: the transaction code, the role of the filer (officer carries more signal than director), and the dollar value relative to the company's market cap. Open-market purchases (P) by C-suite officers carry the strongest bullish signal. Sales (S) referencing a Rule 10b5-1 plan in the footnotes are pre-arranged and should be discounted. See how to read a Form 4 for the full walkthrough.
