Frequently Asked — LRCX Insider Buying
What is LRCX insider buying?
$LRCX insider buying refers to open-market purchases of LAM RESEARCH CORP stock by corporate insiders — officers, directors, and shareholders owning more than 10% of the company. Every purchase is disclosed to the SEC on Form 4 within two business days and is shown on this page.
Why does LRCX insider activity matter?
