Frequently Asked — KRRO Insider Buying

What is KRRO insider buying?

$KRRO insider buying refers to open-market purchases of Korro Bio, Inc. 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 KRRO insider activity matter?

Insiders have the best view into Korro Bio, Inc.'s operations. When they buy their own stock with personal money — rather than selling option grants — it signals conviction. Clusters of insider buying (two or more insiders purchasing within 14 days) have historically preceded above-market returns.

Where does this KRRO insider data come from?

Every transaction on this page is sourced directly from SEC EDGAR Form 4 filings. InsiderAct ingests these filings in near real time and filters for open-market purchases (transaction code P).

How do I get alerts when KRRO insiders buy?

Add $KRRO to your InsiderAct watchlist and enable email alerts. You'll be notified when a new Form 4 purchase is filed — usually within hours of the transaction.

What is a "cluster buy" signal?

InsiderAct flags a cluster buy when two or more independent insiders at the same company buy on the open market within a 14-day window. Cluster buys are the highest-conviction insider signal we track.
