When you ask Gemini about U.S. stocks, do you know where the numbers come from?
Many people use regular Gemini for U.S. stock questions — "How's AAPL doing lately?" — and it gives you an analysis. But are those numbers from today, or from training data six months ago? Whether it actually searched for current data, you have no idea.
RayUSStock AI handles this straightforwardly: after receiving a stock ticker, it forces a search first, includes today's date in the query, then verifies that the data is from the most recent trading day before proceeding with analysis.
Every number in the report must include a source. Fields that can't be found are marked "not available" — it doesn't fill in numbers on its own. After the analysis, there's another round of self-checks: are the stock prices consistent across sections? Are there any discrepancies in financial report dates?
This is the fundamental difference between this Gem and asking Gemini directly.
How is it different from the Taiwan stock Gem?
If you've used RayStock AI (the Taiwan stock version), you might expect the U.S. version to follow the same "institutional investors → dividends → risk" framework. But the analytical logic for U.S. stocks is fundamentally different:
Taiwan stocks focus on institutional flow; U.S. stocks focus on earnings. Taiwan's "three major institutional investors" publish daily buy/sell data — the most immediate market signal. But U.S. institutional holdings (13F) are only published quarterly with a 45-day delay, making them impractical as a core analytical tool. What truly moves U.S. stock prices are earnings — did EPS beat expectations? Is management guidance trending up or down? What do analysts think?
Valuation methods are more diverse. For Taiwan stocks, P/E ratio plus dividend yield usually suffices. But U.S. stocks include growth stocks, value stocks, REITs, financials, and unprofitable SaaS companies — each type requires different valuation metrics. The Gem automatically identifies the stock type and selects appropriate valuation methods.
Shareholder returns go beyond dividends. Many U.S. blue chips (AAPL, META, GOOG) pay minimal dividends, instead returning capital through massive share buybacks. So the U.S. version doesn't call it "dividend analysis" — it's "shareholder returns analysis," covering both dividends and buybacks.
What can it analyze for you?
After opening RayUSStock AI, enter any U.S. stock ticker, and it runs a complete analysis workflow:
Market and Macro Environment: Performance of the S&P 500, Nasdaq, and Dow — the three major indices — plus the 10-year Treasury yield and VIX fear index. If there are upcoming FOMC meetings, CPI data, or nonfarm payroll reports, those are included too.
Real-Time Quotes: Price, change percentage, open/high/low/close, volume, volume-price analysis, position within the 52-week range, and MA50/MA200 moving average alignment.
Earnings and Fundamentals (Core): Did the latest quarter's EPS and revenue beat or miss? By how much? What's the track record over the past four quarters? Is management guidance trending up or down? What ratings and price targets are analysts giving? This section is the heart of the entire report.
Shareholder Returns: For dividend-paying companies — yield, Dividend Aristocrat status, dividend growth rate. For buyback-focused companies — buyback amount, shares outstanding changes, Total Shareholder Yield. For growth-reinvestment companies — free cash flow and ROIC.
Risk Assessment: Beta, debt-to-equity ratio, Short Interest, valuation percentile, earnings event risk, plus recent insider transactions and institutional holdings as supplementary data. Concludes with a risk level.
Overall Rating: From one to five stars, with each rating backed by reasoning that references specific data from the analysis.
ETF Analysis: Enter ETF tickers like SPY, QQQ, VOO, or SCHD, and it automatically switches to ETF mode — tracking index, expense ratio, top 10 holdings, tracking error, and fund flows.
How to start asking?
The simplest way: just enter a stock ticker, such as "AAPL," and it runs the full analysis.
If you only want to check a specific aspect, you can also ask like this:
- "How did NVDA's last quarter earnings look?"
- "Is AAPL's P/E high or low compared to the past five years?"
- "For MSFT, are buybacks or dividends larger?"
- "SCHD's dividend history and yield over the past five years"
- "Compare expense ratios and tracking error between SPY and VOO"
- "Which AI stocks have stronger fundamentals?"
- "How are the three major U.S. indices doing today?"
- "Is TSLA's Short Interest high right now?"
Not every question needs a full analysis — targeted questions get straight to the point.
Tips for getting better answers
The more specific your question, the more useful the answer. "Apple" versus "How much did AAPL beat EPS by last quarter? Was there a guidance adjustment?" are two very different levels of questions — the latter gets a much more targeted response.
If you have doubts about any financial figures, ask it to include source links so you can verify yourself. Build this habit and AI hallucinations become much less likely to trip you up.
Note the time difference for U.S. market hours — during daylight saving time, trading runs from 9:30 PM to 4:00 AM (Taiwan time); during standard time, it's 10:30 PM to 5:00 AM. Data freshness differs depending on whether you ask during or after market hours.
Earnings season (mid-January through mid-February, mid-April through mid-May, mid-July through mid-August, mid-October through mid-November) is the most volatile period for U.S. stocks, with prices often swinging dramatically in after-hours or pre-market following earnings releases. If the stock you're asking about is about to report earnings, the Gem will proactively alert you.
This Gem is positioned as a "research assistant" — it helps you organize data, identify issues, and compare different angles. The actual investment decision is still yours to make, or consult a professional financial advisor.
