How to screen stocks: using conditions to make sense of the market

Taiwan has over a thousand listed and OTC stocks. Screening narrows that down: set conditions, get a list of matches, then research each one.

What screening does

Screening does not find “stocks that will rise”. It narrows more than a thousand stocks into a list you can research one by one. You define conditions (for example “price above the 60-day average” or “revenue up year on year”) and the system lists the stocks that match. The list is a starting point for research, not a conclusion.

Where the conditions come from

The conditions on Tenmizu fall into groups, each answering a different question:

• Trend and moving averages: where price sits relative to the 20- and 60-day averages, describing whether it is currently strong or weak.
• Momentum indicators: KD, RSI, MACD and others, describing the speed and force of recent price moves.
• Volume and liquidity: trading volume and average volume, describing how active trading is and how easily orders fill.
• Chips (flows): institutional net buying and selling, margin and short balances, describing where different types of capital are moving.
• Valuation and growth: P/E, dividend yield, revenue and EPS growth, describing the price level and how the business is changing.

A practical routine

1. Start with a question, then pick conditions. “I want to see companies with steadily growing revenue” is far more concrete than a vague “I want to look at stocks”.
2. Begin with a few conditions. More conditions mean fewer matches; start with two or three and adjust.
3. Mix groups. One group alone can mislead; technical conditions alone say nothing about a company’s finances.
4. Change parameters and watch the list change. Switching the average from 20 to 60 days changes the list a lot, which is itself a way to understand the condition.
5. Research each match. Open the stock page for the chart, financials, flows and announcements; pay attention to flags such as disposition or attention stocks.

Limits to keep in mind

• Conditions are descriptions calculated from historical data; matching one does not mean the same result will follow.
• The same condition can mean different things in different market environments.
• A backtest shows how a combination looked in the past; the past does not guarantee the future.
• The order of the list only follows the column you sort by; it is not a ranking of quality.

Open the Screener, tick conditions and adjust parameters. The Growth screener filters by year-on-year revenue and EPS growth. You can also start from a ranking (for example the dividend yield ranking) and then study each stock page.
