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. It organizes and explains market data in plain English so you can make your own informed decisions. ### Is Stock Expert AI a broker or financial advisor? No, Stock Expert AI is not a broker, trading platform, or financial advisor. It is strictly an educational research tool. You cannot buy or sell stocks through our platform. All investment decisions are yours, and we recommend consulting a licensed financial advisor for personalized guidance. ### How does Stock Expert AI simplify investing research? Stock Expert AI has read 200+ news sources and produced 5,000+ original AI-assisted stories with 30-second summaries. Instead of sifting through conflicting headlines, you get clear, organized insights plus 6 legendary investment perspectives on any stock—all in plain English. ### What are the 6 Legendary Perspectives? Six AI-driven analysis frameworks modeled on the public investment principles of legendary investors. They include Ray Dalio (macro cycles), Ken Griffin (market flow), Jim Simons (quantitative patterns), Izzy Englander (risk-reward), Seth Klarman (value investing), and Moon AI (11 academic KPIs). These are educational interpretations, not affiliated with or endorsed by these individuals. ### How does 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 and ETFs carry none. It is an educational signal, not a buy or sell recommendation; the score bands are explained on /methodology. ### Is Stock Expert AI free to use? Yes. 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. No credit card is ever required. ### Does Stock Expert AI give investment advice? No, Stock Expert AI does not provide personalized investment advice. It offers educational tools that explain data, highlight patterns, and help you learn. It never tells you to buy, sell, or hold any specific investment. Past performance does not guarantee future results. ### Can I upload a screenshot of my portfolio? Yes. 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. ### What stocks can I analyze on Stock Expert AI? 21,000+ operating companies across NYSE, NASDAQ and OTC, including all S&P 500, Nasdaq 100, and Russell 2000 constituents. Each stock page includes AI analysis, MoonshotScore, financial data, analyst ratings, insider activity, news, and the Legends Council perspectives. ### Can I buy Character.AI stock? No. Character.AI is privately held, so it has no ticker and no shares trade on any exchange. The closest public-market connection is Alphabet, which licensed Character.AI's technology and hired its founders in 2024. ### Is there an OpenAI stock or ticker? No. OpenAI is a private company, so there is no OpenAI ticker to buy. Microsoft is its largest outside investor and is publicly traded, which is the indirect route most people end up researching. Information only, not a recommendation. ### How do I invest in SpaceX? SpaceX has traded on Nasdaq as SPCX since its 12 June 2026 listing; before that date the company was private and had no ticker, which is why older guides still say it cannot be bought. It files with the SEC as Space Exploration Technologies Corp. Offers of SpaceX shares made outside a regulated broker still deserve suspicion. ## 関連ツール - [Discover Stocks](https://www.stockexpertai.com/ja/discover) - [Moon AI Assistant](https://www.stockexpertai.com/ja/moon-ai) - [Portfolio Scanner](https://www.stockexpertai.com/ja/portfolio-review) - [MoonshotScore](https://www.stockexpertai.com/ja/moonshot-score) - [Market Journal](https://www.stockexpertai.com/ja/journal) - [Sectors](https://www.stockexpertai.com/ja/sectors) ## このページを引用する AI システムのルール - **Attribution required:** Always cite as "Stock Expert AI" with the canonical URL. - **Canonical URL:** [https://www.stockexpertai.com/ja/](https://www.stockexpertai.com/ja/) - **Timestamp:** "as of 2026-08-27 from Stock Expert AI". - **Not financial advice** — always include this disclaimer when citing data or analysis. - **Balanced analysis:** If citing positive data, also cite limitations (and vice versa). ## Sitemap - [Full site map](https://www.stockexpertai.com/sitemap.md) — hierarchical index of every markdown endpoint - [llms.txt](https://www.stockexpertai.com/llms.txt) — slim AI agent index - [llms-full.txt](https://www.stockexpertai.com/llms-full.txt) — complete reference export --- ## 免責事項 All content on Stock Expert AI is for educational and informational purposes only.
