About this app

In the past, analyzing stock charts might have required several apps: one for monitoring share distribution, one for identifying stocks poised for a surge, one for selecting long-term holdings, one for calculating undervalued stocks, one for ranking dividend yields, and one for tracking monthly revenue. Stock Owl integrates all six into a single app, plus two features most stock selection apps don't offer: multi-factor scoring ranking and strategy backtesting to validate your ideas.

■ Six Stock Selection Lenses, Updated After Market Close Each Trading Day

・Share Distribution Tracking | Who did the major players buy today? See the buying and selling directions of institutional investors, large shareholders, and brokerage firms all at once.

・Short-Term Holding Tracking | Stocks that have just started to strengthen and haven't yet experienced a significant price increase.

・Stable Long-Term Holding | A list of long-term holding stocks with stable fundamentals and dividend records.

・Potentially Undervalued | Value stocks whose prices are currently at relatively low levels compared to their 5-year averages.

・Yield Ranking | Compare cash dividend yields and examine dividend filling records.

・Soaring Revenue | Stocks with record-high monthly revenue and strengthening year-on-year revenue growth.

■ 852 Brokerage Branches: Reverse Analysis of Major Player Buying Activity

Most apps only show branch data for individual stocks. Here, you can reverse the lookup: select a brokerage branch and see which stocks it has recently bought and sold, and which industries it's concentrated in. The individual stock page includes data on institutional investor buying and selling, large shareholder holdings, margin trading, short selling and day trading, multi-range share concentration, and the cumulative line of major and retail investors and the difference between the number of buy and sell orders.

■ Individual Stock Page: Conclusion First, Evidence Later

Each stock has four indicators at the top: valuation, fundamentals, shareholding structure, and momentum, giving a clear picture of its current state. Further down, it's divided into six pages: key points, company fundamentals, buying and selling trends, dividends, technical charts (K-line and moving averages), and more analysis. Valuation river charts, dividend statistics, peer comparisons, rule scanning, and regular fixed-amount calculations are all included.

The indicators will honestly turn off. The valuation light will automatically adjust its reference value in unsuitable market environments, while the volume indicator light will never alert you to enter the market simply because of "major players buying in large quantities"—that's a signal we've tested and failed to validate.

■ Ranking and Strategy Backtesting

・Market-wide Ranking: Listed and OTC stocks are ranked separately, showing their rankings and key metrics.

・Custom Stock Selection: Create and save your own stock selection list using fundamentals, volume indicators, and technical factors.

・Strategy Backtesting: Run your stock selection rules against historical data, viewing returns and maximum drawdowns together, along with stress tests and reliability explanations (the environment in which they succeed, reliance on a few winners, and the impact of costs and slippage).

We not only give you signals, but also the tools to verify them.

■ Price Target Notifications and Event Alerts: Set a target price, and receive notifications after the market closes or when it's reached during the trading day; signal lights for held stocks and watchlists will also be proactively sent, along with exit warnings for held stocks. Every morning, there's a "Today" summary, focusing only on real changes and avoiding repetition of yesterday's content.

■ Commonly Used Tools: Ex-dividend calendar, monthly revenue updates (including pre- and post-announcement returns), ETF section (constituent stocks, industry weighting, premium/discount, size, number of beneficiaries, dividend income composition, regular fixed-amount calculation), brokerage branch lookup, custom conditional filters, and custom grouping and stock holding tracking.

■ Data and Updates: Updated daily after market close for all listed and OTC markets, with the actual data date indicated on the list; listed companies are updated first, followed by OTC companies after data is completed. Historical data is available since 2016 and has been reconstructed daily based on ex-dividend, capital reduction, and stock splits; backtesting and return calculations use the reconstructed prices.

■ Free and StockOwl Pro: Free registration and login to use: six stock selection lenses, individual stock candlestick charts and basic information, dividend records, custom stock selection and holding tracking, and closing price notifications.


StockOwl Pro offers: Brokerage commission details and exit signals, intraday price alerts and event reminders, complete backtesting parameters and dividend tax calculations, as well as longer lists and higher notification levels, strategies, and screening limits. The subscription is automatically renewed monthly and can be canceled at any time in the app store's subscription settings; it remains available until the end of the current period. Accounts can be deleted with a single click within the app.

■ All You Need in One App

Want to know if stock market sentiment has shifted? Stock tracking combined with commission reversal shows who is buying and who is selling.

Want to catch the first phase of a stock market rally? Rally tracking with K-lines and moving averages allows you to view the list first, then the chart.

Want to find fixed-term deposit stocks and estimate their value? A list of stable fixed-term stocks is paired with valuation river charts and dividend yield statistics.

Want to compare stock yields? See yield rankings along with dividend yield records, not just the numbers.

Want to track companies with soaring revenue? Monthly revenue updates are continuously provided during the monthly revenue release season. To verify your method's effectiveness: run the backtest using ten years of historical data.

■ What We Don't Do
We do not recommend individual stocks, do not manage client funds, do not provide buy/sell advice, do not offer order placement functionality, and will not ask you to join any groups or purchase courses. The weight composition of the algorithm is a trade secret and will not be disclosed, but publicly available data for self-verification is provided alongside each conclusion.

All data comes from publicly available information and may be delayed, incomplete, or inaccurate.
