THE KEY IDEA
A screener narrows a research universe. Passing the filters is the start of investigating a company, not a recommendation to buy it.
Start with a question you can explain
A stock screener filters companies using defined criteria, such as size, profitability or dividend yield. Starting with a clear question makes the result easier to interpret: for example, which dividend payers also pass checks on payout coverage and financial strength?
Use a ready-made strategy to learn the relationship between its purpose and its filters. Then open the criteria rather than relying on the strategy’s name. A useful shortlist should be understandable enough that you can explain why a company appears in it.

Learn from PortfolioX’s ready-made strategies
PortfolioX includes strategies for dividend income, companies with strong finances, and businesses generating cash. The Dividend Income preset combines a dividend-yield range with payout and financial-strength checks. The criteria shown in the app are the place to confirm its current thresholds.
Other discovery views highlight stocks near their 52-week highs or lows. Being near a low describes a price’s position in its recent range; it does not establish that a business is undervalued. Use the result as a question to investigate.
Change one filter, then examine the result
With Premium, you can customize filters and save screens in PortfolioX. Change one condition at a time so you can see which companies enter or leave the results. A highly restrictive screen can exclude useful candidates as well as weak ones.
Open a matched company and inspect its earnings, financial position, dividend record and valuation context. A metric can be missing, stale or unsuitable for a particular industry. A watchlist gives you a place to follow candidates while you continue researching, without treating a screen as a trade signal.
Take a shortlist into company research
Use the live results in PortfolioX to find current matches. The companies below are research examples only: this guide does not claim they pass any preset today. Open the same sections for a real match and ask whether the financial story explains the screening metrics.
Amazon’s financial information provides one company to practice reading beyond a headline valuation.
Meta’s earnings offer an example of checking a recent result before relying on a profitability metric.
Broadcom’s dividend history lets you investigate payment information alongside an income-oriented screen.
WORKED EXAMPLE
Turn “find income ideas” into a research process
An illustrative workflow, not recommended thresholds or a list of securities to buy.
- Start
- Open the Dividend Income strategy
- Understand
- Read the yield, payout and quality criteria
- Investigate
- Check a match’s earnings and dividend history
- Follow
- Add a candidate to a watchlist
A company can meet every numeric condition and still have risks the screen does not capture. Use the shortlist to decide what deserves a closer look.
Common mistakes to avoid
- Adding many filters without understanding which question each one answers.
- Assuming missing data means zero or that the same ratio suits every industry.
- Treating a low price, a high yield or a saved strategy as a guarantee of future returns.
Questions answered
Which stock screener filters should a beginner start with?
Start with one clear research question and a ready-made strategy whose criteria you understand. Read each condition and inspect a few results before adding more. For example, an income-focused strategy can combine dividend yield with payout and financial-strength checks. The thresholds describe the screen; they are not universal rules for what makes a good investment.
Why did a company disappear from my screener results?
Its price or financial data may have changed, or you may have changed a filter, range or selected universe. Data coverage can also affect eligibility. Recheck the active criteria and the company’s latest available figures one condition at a time. Leaving a result set does not by itself mean the company became a bad investment.
Can I use PortfolioX’s stock screener without Premium?
Yes. You can explore the ready-made strategies without Premium and open companies from their results. Premium adds custom filters and saved screens. Start by understanding a preset’s applied conditions, then decide whether you need to build and revisit your own combination. Multiple watchlists are also a Premium feature.
