Frequently Asked — SBOT Insider Buying

What is SBOT insider buying?

$SBOT insider buying refers to open-market purchases of Stellar Biotechnologies, 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 SBOT insider activity matter?

Insiders have the best view into Stellar Biotechnologies, 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 SBOT insider data come from?
