Frequently Asked Questions
What is Stock Expert AI?
Stock Expert AI is a free AI-powered stock research platform for self-directed investors. It covers 21,000+ US stocks. Each gets a MoonshotScore (0-100) where fundamentals support one, an AI dossier and portfolio diagnostics. Educational only; not a broker or adviser.
Is Stock Expert AI free?
Every stock page is free to read without an account, and there is no subscription. A free account is needed for the tools that save or generate something for you — watchlists, the portfolio screenshot scanner, virtual trading and the Moon AI assistant — and those AI features carry a daily allowance.
How does the MoonshotScore work?
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.
Who is Stock Expert AI for?
Self-directed investors — people who choose their own holdings and want the research behind a decision rather than the decision itself. Active traders and long-term holders use the same pages; nothing here is tailored to a risk profile or an account.
Where does your data come from?
Financial Modeling Prep is the primary source, with Yahoo Finance and Alpaca as fallbacks and SEC EDGAR for filings. Prices refresh when a page is viewed during US market hours; outside those hours they are the last close. Each quote is a provider snapshot, not an exchange feed. Financial statements update after each quarterly filing, and every AI analysis carries the date it was written.
Is my portfolio data secure?
Stock Expert AI never links to a brokerage account. Upload a screenshot of your brokerage portfolio or enter positions by hand; OCR reads the holdings, then the scanner returns educational insights on diversification, concentration risk, sector exposure and overall portfolio health. It never tells you to buy, sell or hold a specific investment.
Do you provide financial advice?
No. Stock Expert AI is an educational and research platform. All analysis, scores, and insights are for informational purposes only and should not be interpreted as financial advice.
How is Stock Expert AI different from other platforms?
Stock Expert AI combines AI-powered analysis, portfolio health scanning, community predictions, and the MoonshotScore rating system in a single free platform. Every page states its data sources and the date of the analysis it shows.
