Stock Screener Fundamental Ratio Singapore
The key financial ratios Singapore investors filter for when screening SGX stocks
A stock screener fundamental ratio is a standardised financial metric — such as P/E, P/B, dividend yield, or debt-to-equity — used to filter and compare SGX-listed stocks against a set of numerical criteria, helping investors narrow down a large universe of counters to a shortlist worth deeper research.

Key Takeaways
- Fundamental ratios used in stock screening fall into broad categories: valuation (P/E, P/B), profitability (ROE, net margin), income (dividend yield, payout ratio), and financial health (debt-to-equity, interest coverage).
- A stock screener applies these ratios as filters across hundreds of SGX-listed counters simultaneously, turning a manual research process into a fast, rules-based shortlist.
- No single ratio tells the full story — a low P/E could signal undervaluation or could reflect a genuinely troubled business, which is why screeners are a starting point, not a final decision tool.
- Singapore investors commonly combine sector-relative screening (comparing a REIT’s P/B against other REITs, not against a bank) since fair ratio ranges differ significantly by industry.
- Free and paid stock screener tools covering SGX include SGX StockFacts, Ahrefs-adjacent financial data platforms, and brokerage research portals from local banks and brokers.

What Is a Stock Screener Fundamental Ratio?
With over 600 companies listed on SGX, manually researching every stock is impractical for most individual investors. A stock screener is a tool that lets you set numerical filters based on fundamental ratios — financial metrics derived from a company’s income statement, balance sheet, and market price — to instantly narrow the universe of stocks down to those meeting your specific criteria.
Fundamental ratios generally fall into four categories: valuation ratios (like price-to-earnings and price-to-book, which compare a stock’s price to its earnings or asset value), profitability ratios (like return on equity, which measures how efficiently a company generates profit from shareholder capital), income ratios (like dividend yield and payout ratio, important for income-focused Singapore investors), and financial health ratios (like debt-to-equity and interest coverage, which gauge a company’s ability to service its debt).
A screener doesn’t tell you which stock to buy; it simply filters a large universe down to a manageable shortlist based on your chosen thresholds, after which deeper qualitative and quantitative research is still required before making an investment decision.
Beyond the standard set of valuation, profitability, income, and financial health ratios, more advanced Singapore stock screens sometimes incorporate REIT-specific metrics (like gearing ratio, interest coverage ratio, or price-to-NAV) or growth-oriented metrics (like revenue CAGR or earnings growth consistency) depending on the investor’s specific strategy. Building a genuinely useful screener setup usually means starting broad (basic valuation and financial health filters to eliminate obviously unsuitable candidates) and then progressively narrowing with strategy-specific criteria as the shortlist gets smaller, rather than trying to apply every possible filter simultaneously from the start, which risks eliminating potentially good candidates due to an overly restrictive single metric.
How Does Screening Work for SGX Stocks?
Most stock screening platforms let you input a combination of criteria — for example, “P/E below 15, dividend yield above 4%, debt-to-equity below 1.0” — and the tool instantly returns every SGX-listed stock meeting all three conditions simultaneously. This is far faster than manually checking each ratio for hundreds of individual counters.
Singapore-specific screening tools include SGX’s own StockFacts platform (which provides free basic fundamental data for all SGX-listed companies), brokerage research portals from banks like DBS, OCBC, and UOB (often available to account holders), and third-party financial data platforms that cover SGX alongside global markets. Some investors also build custom screeners using spreadsheet exports from these sources, allowing more granular, personalised filter combinations.
A key nuance for SGX screening is sector context: comparing a REIT’s P/B ratio against a technology company’s P/B ratio is meaningless, since REITs are asset-heavy and typically trade close to their net asset value, while tech companies often trade at multiples far above book value due to intangible growth expectations. Effective screening usually means filtering within a sector or applying sector-adjusted benchmark ranges.
Stock Screener Example
An investor wants to find Singapore blue-chip dividend stocks. She sets a screener filter: market capitalisation above S$1 billion, dividend yield above 5%, payout ratio below 80%, and interest coverage ratio above 5x. Running this across the full SGX universe returns a shortlist of perhaps 15-20 stocks, down from over 600 — a manageable list she can now research individually for business quality, growth prospects, and dividend sustainability before making any investment decision.
Many Singapore investors also find it useful to save and periodically revisit a shortlist of stocks that previously passed a screen but were not purchased, since business fundamentals and valuations shift over time and a stock once screened out on price alone can become attractive again after a subsequent pullback.
Advantages of Using Fundamental Ratio Screens
- Massively speeds up initial research. Screening turns a task that could take days of manual checking into a filter applied in seconds across the entire SGX universe.
- Removes emotional bias from the first pass. Applying objective numerical criteria before looking at a company’s story or recent news helps avoid chasing hype-driven stocks that don’t meet basic fundamental standards.
- Customisable to your investment strategy. Dividend investors, value investors, and growth investors can each build screener criteria tailored to their specific approach and risk tolerance.
- Helps discover overlooked stocks. A well-designed screen can surface smaller or less-covered SGX counters meeting strong fundamental criteria that wouldn’t otherwise appear on an investor’s radar through news or word-of-mouth alone.
Risks and Limitations
- Ratios are backward-looking. Most fundamental ratios are calculated from historical financial statements and don’t capture forward-looking changes in a company’s business, industry, or competitive position.
- Single-ratio traps. A low P/E might indicate undervaluation, or it might reflect a genuinely deteriorating business the market has correctly priced down — screening alone can’t distinguish between the two.
- Sector mismatches distort comparisons. Applying the same absolute ratio thresholds across different industries (REITs, banks, tech, manufacturing) produces misleading results, since “normal” ratio ranges vary significantly by sector.
- Data quality and timeliness vary by platform. Free screeners may lag on the latest quarterly results or use slightly different calculation methodologies, so cross-checking key figures against the company’s actual financial statements is worthwhile before acting.
- Screening is a starting point, not a conclusion. A stock that passes every filter still requires qualitative research — management quality, competitive moat, industry outlook — before it becomes a genuine investment candidate.
Common Fundamental Ratios and What They Measure
| Ratio | Category | What It Measures |
|---|---|---|
| Price-to-Earnings (P/E) | Valuation | Price paid per dollar of company earnings |
| Price-to-Book (P/B) | Valuation | Price paid relative to net asset value |
| Dividend Yield | Income | Annual dividend as a percentage of share price |
| Payout Ratio | Income/Sustainability | Percentage of earnings paid out as dividends |
| Return on Equity (ROE) | Profitability | Profit generated per dollar of shareholder equity |
| Debt-to-Equity | Financial Health | Leverage relative to shareholder capital |
| Interest Coverage Ratio | Financial Health | Ability to service debt interest from earnings |
It’s also worth setting screener alerts or periodically re-running the same screen over time, since a stock’s fundamental ratios change as new quarterly results are released, meaning a one-time screening exercise can quickly become outdated if not refreshed regularly as part of an ongoing research routine.
The Bottom Line
For Singapore investors, a stock screener built on fundamental ratios is a powerful first-pass filter for narrowing SGX’s 600-plus listed companies down to a manageable research shortlist, but it works best combined with sector context and followed by deeper qualitative research, not as a standalone buy signal.
Frequently Asked Questions
Is SGX StockFacts free to use for stock screening?
Yes, SGX’s StockFacts platform provides free access to basic fundamental data and financial ratios for all SGX-listed companies, making it a reasonable starting point for Singapore retail investors.
What is a good P/E ratio for SGX stocks?
There’s no universal ‘good’ P/E — it depends heavily on the sector, growth prospects, and prevailing market conditions. Comparing a stock’s P/E against its own historical average and sector peers is more meaningful than an absolute number.
Can I screen SGX stocks by dividend yield alone?
You can, but a high dividend yield in isolation can sometimes signal a falling share price (which mechanically raises yield) or an unsustainable payout, so pairing yield with payout ratio and earnings trend gives a fuller picture.
Why do REITs and banks have such different 'normal' ratio ranges?
REITs are structurally required to distribute most of their income and are valued more like asset-backed vehicles, while banks are valued on earnings growth, capital ratios, and credit quality — different business models naturally trade at different typical multiples.
Do brokerage platforms offer built-in stock screeners for SGX?
Many Singapore brokerages and banks provide research portals with basic screening functionality for account holders, though the depth of filters and data quality vary by provider.
Should I only invest in stocks that pass my screener's criteria?
A screener should be treated as a research starting point, not a final decision rule — stocks that pass still need deeper qualitative and quantitative analysis before an investment decision is made.
