Price to Sales Ratio
A metric used to compare a company’s stock price to its revenue, indicating how much to pay in stock price for each dollar of revenues
What Is The Price-to-Sales (P/S) Ratio?
The price-to-sales (P/S) ratio is a handy metric for investors looking to calculate a company's value relative to its revenue.
Unlike the price-to-earnings (P/E) ratio, which zeroes in on earnings, the P/S ratio focuses on sales, making it particularly useful for assessing companies that might not yet be profitable or have erratic earnings.
This ratio is applicable in industries where growth in sales is a key measure of future success, although profits may not yet be essential.
Grasping the P/S ratio is able to assist investors in identifying potential opportunities and more successfully riding the roller coaster of the stock market. It provides a clearer view of a firm's market position and potential for growth.
- The Price-to-Sales ratio evaluates a company's value based on revenue, which is useful for non-profitable companies.
- The ratio is calculated by dividing market capitalization by total sales, highlighting sales growth potential.
- The ratio is of two types: Trailing and Forward. Trailing P/S uses historical sales and gives us a clear picture of how the business has been performing. Forward P/S uses projected sales, which are less reliable, but it gives us an idea of how a business will be valued if it meets expectations, which is a more valuable insight.
- The ratio doesn't account for debt, varies across industries, and can be distorted by temporary factors.
- High-growth sectors often have higher P/S ratios; cyclical sectors see more variation with economic cycles.
Understanding Price-to-Sales (P/S) Ratio
Price-to-sales ratio, or P/S ratio, is a measure in finance that helps investors compare a firm's valuation with its earnings. The company's market value (market value of the existing shares) over its overall sales or revenue generated during a limited period of time, say last 12 months, is to be divided when computing P/S ratio.
The formula is:
P/S Ratio = Market Capitalization / Total Sales
Here’s a step-by-step explanation:
- Market Capitalization: This is a company's entire value of stock shares. It is found by multiplying the existing stock price and the number of outstanding shares.
- Total Sales (Revenue): This is the total amount of money a company has brought in from its business activities, like sale of products or services, over the past year.
- Calculating the P/S Ratio: You divide the market capitalization by the total sales. For example, if a company has a market capitalization of $1 billion and total sales of $500 million, the P/S ratio would be 2
P/S Ratio = $1 billion / $500 million = 2
Why Is the Price-to-Sales (P/S) Ratio Useful?
Whilst the P/S Ratio is useful as a metric in general, there are specific circumstances where it shines. In particular:
- Valuation of Early-Stage Companies: Like many startups, the P/E ratio isn't useful for companies that are not yet profitable because they have little to no earnings. The P/S ratio, however, can yet provide insight by focusing on sales.
- Sales Growth Assessment: For companies with strong sales growth but inconsistent earnings, the P/S ratio highlights the value the market places on those sales, offering a clearer picture of potential future success.
Examples of the Price-to-Sales (P/S) Ratio
Let's calculate the ratio of three hypothetical companies.
For all three companies, companies A, B, and C, we'll assume they are all trading at $10 per share and have 200 million shares outstanding.
With these assumptions, we can calculate the market capitalization for each company. The market capitalization =
$10 share price x 200 million shares outstanding = a market cap of $2 billion
Next, we'll assume the hypothetical sales of each company in the last twelve months.
- Company A: Sales of $1.6 billion
- Company B: Sales of $1.2 billion
- Company C: Sales of $2 billion
Let's say these companies have very different earnings numbers, and company C has negative earnings. In this case, the P/E ratio provided very minimal insight into the valuation of the three companies, so we need to use the P/S ratio.
Since company C is not yet profitable, we can better understand these companies' values by calculating the ratio.
- Company A: $2 billion / $1.6 billion = 1.25x
- Company B: $2 billion / $1.2 billion = 1.67x
- Company C: $2 billion / $2 billion = 1x
In this comparison, company C is the most attractive investment because it has the lowest ratio. This means that it is the cheapest stock to buy for the number of sales the company has.
This example shows why the ratio is more useful for companies struggling to make a profit or are unprofitable. The P/E ratio cannot determine which company is the most valuable when the companies are not making consistent earnings.
The P/S ratio, on the other hand, can easily determine the relative value of companies that are not profitable because it does not take into account earnings. Even though company C has negative earnings, it is the most attractive company out of the three in terms of sales.
Types of P/S Ratios
When valuing a company, you can use two data sets to determine your P/S ratio: the last twelve months (LTM) and the next twelve months (NTM). This gives you two different ratios:
1. Trailing P/S Ratio: Uses the company's revenue from the last twelve months (LTM). It is calculated by dividing the current market capitalization by the total sales over the last year.
Trailing P/S Ratio = Market Capitalization / Total Sales(LTM)
2. Forward P/S Ratio: Uses projected revenue for the next 12 months (NTM). It is calculated by dividing the current market capitalization by the forecasted total sales for the next year.
Forward P/S Ratio = Market Capitalization / Projected Sales(NTM)
Trailing P/S Ratio Vs. Forward P/S Ratio
The differences between these two ratios lead to distinct use cases, making it essential to understand them. Some differences are:
| Trailing P/S Ratio | Forward P/S Ratio | |
|---|---|---|
| Data Source | It utilizes historical data (actual sales). | It is based on future estimates (projected sales). |
| Reliability | It is based on actual results, making it more reliable. | It depends on predictions, which can be uncertain. |
| Use Case | It is useful for evaluating past performance | It helps gauge future growth potential. |
Limitations of the Price-to-Sales (P/S) Ratio
The central idea of the P/S Ratio is that we can use it to analyze companies that aren’t yet profitable or have high earnings variability. However, ignoring profitability means there are some important details that this figure also ignores:
- Ignoring Debt and Capital Structure: The P/S ratio does not reflect a firm's debt level or capital structure. A firm with high debt can be riskier financially even if it has a desirable P/S ratio.
- Variability Across Industries: As is standard in finance, different industries have different average P/S ratios. High-growth industries, like technology, often have higher P/S ratios compared to mature industries, like utilities. Comparing P/S ratios across different industries is not advisable.
- Potential for Manipulation or Distortion: Revenue can be affected by temporary factors such as one-time sales or seasonal fluctuations, which can distort the P/S ratio. Aggressive sales tactics or revenue recognition practices can also artificially inflate this ratio, misleading investors.
Use of the P/S ratio in different sectors
Whilst every company will have a P/S ratio, and it can always give you some insight, it is significantly more useful in these particular sectors:
High-Growth Sectors (e.g., Technology and Biotech)
Many of these companies will be unprofitable for long periods hence P/S is the ratio of choice.
- High-growth sectors like technology and biotechnology prioritize increasing revenue over immediate profitability.
- These industries often have higher P/S ratios due to investor expectations of strong future growth.
- A tech startup might have a high P/S ratio because of its potential for rapid growth and innovation, even if it isn't yet profitable.
- A high P/S ratio is acceptable if the company demonstrates significant growth potential and market demand.
Cyclical Sectors (e.g., Automotive and Energy)
The P/S ratio is an effective metric for evaluating companies in cyclical industries because it focuses on revenue. This provides stability and mitigates the impact of seasonal and economic fluctuations.
- The P/S ratio provides a stable measure of value by focusing on revenue, which is less volatile than earnings in cyclical industries.
- It highlights the company's ability to generate sales, which can be more consistent than profits during economic cycles.
- By considering the past 12 months of revenue, the P/S ratio smooths out the effects of seasonality and economic fluctuations.
- It allows for effective comparison between companies within the same cyclical sector, where earnings can be inconsistent.
Price-to-Sales Ratio FAQs
While useful, the P/S ratio may not be as relevant for mature companies with stable earnings, where the P/E ratio might be more informative.
No, the P/S ratio cannot be negative because sales and market capitalization are always positive numbers.
The P/S ratio is typically calculated quarterly or annually, coinciding with a company's financial reporting periods.
Inflation can affect sales and market capitalization, potentially distorting the P/S ratio. Investors should consider inflation's impact on both metrics.
Yes, aggressive sales tactics or changes in revenue recognition practices can artificially inflate sales figures and the P/S ratio. Investors should review the quality of earnings reports.
