SubscribeFrequently asked questions
Q.Is it free to use?
Yes, every feature on US STOCK TODAY is free.
Q.How often is the data updated?
Financial and fundamental data are updated daily after the U.S. market close, while prices stream in real time during regular, pre-market, and after-hours sessions via Yahoo WSS.
Q.What indicators do you provide?
We provide 87 investing metrics — valuation (P/E, P/B), profitability (ROE, ROA), and technical indicators (RSI, MACD, Bollinger Bands) — along with 17 economic indicators such as CPI, FOMC, GDP, and employment, each with a beginner-friendly definition.
Q.Can I trust AI-written articles?
Numbers are never generated by AI. Values are pulled from the database by code and inserted into sentences, while AI writes the prose around them. A separate review step before publication flags any factual violations, and articles that fail are not published. Note that nothing here is a buy or sell recommendation — investment decisions are your own responsibility.
Q.How can I see how AI Picks perform?
Each pick is logged as one bet. We pin the price at publication and, one month later, compare the return to the S&P 500 (SPY) over the same window to mark it win or loss. Even picks with poor results are never deleted or edited — all of them stay public.
Q.Do you support languages other than Korean?
Yes — Bahasa Indonesia is available. Add /id to the URL or use the language button on the right side of the screen to switch. Articles without a translation will appear in the original Korean.
Q.Can I use it on mobile?
Yes, the mobile-optimized UI makes it easy to browse on the go. However, in-depth data analysis works best on a wider desktop screen.
