In plain terms

When two or more independent bullish signals fire on the same stock within two months, the joint conviction is much stronger than any single signal.

How it works

≥2 independent long-side signals (Phase-3 readout, activist 13D, Form 4 cluster buying, corp-jet target leak, fast-track FDA) within 60d amplify joint long conviction.
