“MoonshotScore rates a US-listed stock 0 to 100 — higher means stronger numbers. Most carry an older nine-factor score; the rest use five sector-relative pillars, re-ranked daily — common stocks and ADRs only. Funds, ETFs, warrants, units, SPACs, preferreds, and notes carry none. It is built for education and deeper due diligence, not financial advice.”
