Price-to-Sales Ratio (P/S) Singapore
Valuing a stock against its revenue when earnings don’t tell the full story
Price-to-Sales Ratio compares a company’s market capitalisation to its total revenue, calculated as share price divided by revenue per share (or market cap divided by total revenue). It is especially useful for valuing companies with low or negative earnings.

- Price-to-Sales Ratio (P/S) = Market Capitalisation ÷ Total Revenue, or Share Price ÷ Revenue Per Share.
- P/S is useful when a company has negative or volatile earnings, since revenue is harder to manipulate than profit.
- A lower P/S can suggest a stock is undervalued relative to its sales, but must be checked against profit margins.
- Singapore growth stocks and early-stage companies are often valued using P/S before they reach consistent profitability.
- P/S should always be compared within the same sector, since acceptable multiples vary hugely by business model and margin profile.

What Is Price-to-Sales Ratio?
The Price-to-Sales Ratio (P/S) compares a company’s total market value to its revenue, calculated as Market Capitalisation ÷ Total Revenue, or equivalently, Share Price ÷ Revenue Per Share. It shows how much investors are willing to pay for each dollar of a company’s sales.
P/S is particularly valuable for valuing companies that are not yet profitable, or whose earnings are volatile or temporarily depressed, since revenue figures are generally more stable and harder to manipulate through accounting choices than net income.
The ratio is most commonly used for growth companies, cyclical businesses at the bottom of a down-cycle, or any business where price-to-earnings (P/E) isn’t meaningful because earnings are negative or near zero.
How Does Price-to-Sales Ratio Work in Singapore?
Singapore investors apply P/S most often to early-stage technology, healthcare and biotech companies listed on the SGX or Catalist board, where earnings may still be negative as the business scales, but revenue growth is a clearer signal of market traction. P/S is also used for cyclical sectors like shipping and commodities during industry downturns, when earnings temporarily collapse but revenue remains a more stable reference point.
Because P/S ignores profitability entirely, Singapore analysts typically pair it with a profit margin check — a company with a low P/S but also very low or negative margins may not actually be cheap once the path to profitability is factored in.
| Use case | Why P/S is used |
|---|---|
| Early-stage growth / tech stocks | Earnings are negative or near zero |
| Cyclical downturn | Earnings temporarily depressed, revenue more stable |
| Turnaround situations | Comparing against pre-crisis revenue levels |
Price-to-Sales Ratio Example
Suppose a Singapore-listed technology company has a market capitalisation of SGD 500 million and reports annual revenue of SGD 100 million.
P/S Ratio = SGD 500 million ÷ SGD 100 million = 5x.
This means investors are paying SGD 5 for every SGD 1 of the company’s annual revenue. If a direct competitor with similar growth and margin prospects trades at only 3x P/S, the first company could be considered relatively more expensive on a sales basis — though the comparison should also factor in growth rates and profit margins before drawing a valuation conclusion.
Advantages of Price-to-Sales Ratio
- Works for unprofitable companies: P/S remains meaningful even when P/E is unusable due to negative earnings.
- Revenue is harder to manipulate than profit: sales figures are generally more consistent and transparent than net income, which can be affected by accounting choices.
- Useful across business cycles: P/S provides a stable valuation reference even when profits are temporarily depressed in a downturn.
- Simple and quick to calculate: both market capitalisation and revenue are readily available for any listed company.
Risks and Limitations
- P/S completely ignores profitability — a company can have an attractive P/S while losing money with no clear path to profit.
- Comparing P/S across sectors with very different margin structures (e.g. software vs. commodities trading) is not meaningful.
- Revenue growth achieved through heavy discounting or unsustainable customer acquisition spending can make P/S look artificially cheap.
- P/S doesn’t account for a company’s debt level, unlike enterprise-value-based multiples.
Price-to-Sales Ratio vs Price-to-Earnings Ratio
| Feature | Price-to-Sales Ratio | Price-to-Earnings Ratio |
|---|---|---|
| Denominator | Revenue | Net income |
| Usable with negative earnings? | Yes | No — P/E is meaningless with negative earnings |
| Accounts for profit margin? | No | Yes, implicitly |
The Bottom Line
For Singapore investors, Price-to-Sales Ratio is important because it provides a usable valuation yardstick for companies where price-to-earnings breaks down — especially growth stocks and cyclical businesses in a downturn. It works best when paired with a profit margin and growth rate check, rather than used as a standalone valuation signal.

Frequently Asked Questions
What is a good Price-to-Sales Ratio?
There’s no universal benchmark — it depends heavily on the sector’s typical margin profile. High-margin software companies can justifiably trade at higher P/S multiples than low-margin trading or commodity businesses.
How is Price-to-Sales Ratio calculated?
P/S = Market Capitalisation ÷ Total Revenue, or equivalently, Share Price ÷ Revenue Per Share.
Why use P/S instead of P/E?
P/S remains usable when a company has negative or near-zero earnings, which makes the price-to-earnings ratio meaningless, making P/S especially useful for early-stage growth companies and cyclical businesses in a downturn.
Does a low P/S always mean a stock is cheap?
Not necessarily. A low P/S should be checked against the company’s profit margins and growth outlook — a company with persistently poor margins may deserve a lower P/S rather than representing a bargain.
Is Price-to-Sales Ratio useful for Singapore REITs?
P/S is rarely used for REITs, since their valuation is better captured by metrics like Price-to-NAV and Distribution Yield, which more directly reflect property income and asset value.
