Looking at a company's share price tells you only one small part of the story. A stock trading at ₹100 is not necessarily cheaper than a stock trading at ₹500. To understand what is happening behind the share price, investors need to look at the company's earnings, valuation and financial performance. This is where basic financial ratios can become useful.
For anyone learning about the Indian stock market, three numbers that frequently appear during company research are EPS, P/E Ratio and ROE. Although these terms may sound technical, their basic purpose is quite simple. EPS helps you understand earnings on a per-share basis, P/E gives you an idea about how the market values those earnings, and ROE shows how effectively a company uses shareholders' money. Understanding these three concepts can give beginners a useful starting point for studying businesses.
Why Financial Ratios Matter?
Imagine that you are comparing two companies. Both have strong brands and their share prices have increased over time. At first glance, they may both look attractive.
But what if one company is generating much higher profits? What if the second company is being valued much more highly by investors? What if one company is using its capital more efficiently?
The share price alone cannot answer these questions.
Financial ratios help turn large amounts of financial information into numbers that are easier to understand. They do not provide the complete picture, but they can help investors identify areas that deserve further research.
Let us look at three important ratios one by one.
1. EPS: How Much Profit Belongs to Each Share?
EPS stands for Earnings Per Share.
In simple terms, EPS tells you how much of a company's profit is attributable to each outstanding share.
The basic calculation is:
EPS = Net Profit ÷ Number of Outstanding Shares
Consider a simple example.
Suppose a company reports a net profit of ₹100 crore and has 20 crore outstanding shares.
Its EPS would be:
₹100 crore ÷ 20 crore = ₹5
So, the company's earnings amount to ₹5 for each outstanding share.
Why Should You Look at EPS?
EPS can help you assess a company's profitability from a shareholder's perspective.
However, the current EPS number is only one part of the analysis. It can be more useful to observe how EPS has changed over several years.
For Example:-
| Year | EPS |
| Year 1 | ₹4 |
| Year 2 | ₹4.80 |
| Year 3 | ₹5.70 |
| Year 4 | ₹6.90 |
This pattern suggests that earnings per share have been increasing.
On the other hand, if EPS keeps falling or changes dramatically from one year to another, you may want to investigate the reasons.
A decline could be related to lower profits, higher expenses, additional shares being issued or other changes in the business.
One Important Point About EPS
A higher EPS does not automatically make one company better than another.
A large company and a small company can have very different EPS figures because they may have different numbers of outstanding shares.
Therefore, EPS is more useful when studied alongside other financial information.
2. P/E Ratio: What Are Investors Paying for Earnings?
P/E stands for Price-to-Earnings Ratio.
While EPS tells you about earnings per share, P/E connects those earnings with the current market price.
The basic formula is:
P/E Ratio = Current Share Price ÷ EPS
Suppose a company's share is trading at ₹250 and its EPS is ₹10.
The calculation would be:
₹250 ÷ ₹10 = 25
Therefore, the company's P/E Ratio is 25.
In simple terms, P/E helps you understand the relationship between the price investors are currently paying for a share and the company's earnings per share.
Is a High P/E Bad?
Not necessarily.
A high P/E may indicate that investors have strong expectations about the company's future growth. They may believe that the company's earnings can increase significantly in the coming years.
For example, a company operating in a rapidly expanding industry may receive a higher valuation because investors expect its future profits to grow.
However, high expectations can also create risk.
If the company fails to deliver the growth investors expected, the market may reduce the valuation placed on the stock.
Therefore, a high P/E should be investigated rather than automatically considered positive or negative.
Is a Low P/E Good?
Again, not necessarily.
A low P/E may make a company appear inexpensive compared with its current earnings. But there could be a reason why investors are assigning a lower valuation.
The company could be facing:
- Slower business growth
- Weak industry conditions
- High debt
- Falling profits
- Increased competition
- Uncertainty about future earnings
This is why simply searching for stocks with the lowest P/E Ratio can be misleading.
Compare P/E With Similar Companies
P/E becomes more meaningful when you compare companies operating in similar industries.
For example, if most companies in an industry trade around a P/E of 25 to 30 and one company trades at 10, that difference may deserve investigation.
But the reason for the lower valuation matters more than the number itself.
3. ROE: How Efficiently Is the Company Using Shareholders' Capital?
ROE stands for Return on Equity.
This ratio looks at the relationship between a company's profit and the equity contributed by its shareholders.
The basic formula is:
ROE = Net Profit ÷ Shareholders' Equity × 100
Suppose a company has:
- Net profit = ₹30 crore
- Shareholders' equity = ₹150 crore
Its ROE would be:
₹30 crore ÷ ₹150 crore × 100 = 20%
This means the company generated ₹20 in profit for every ₹100 of shareholders' equity.
Why Does ROE Matter?
A business requires capital to operate and expand. ROE provides one way of looking at how efficiently the company is turning shareholders' capital into profit.
A consistently healthy ROE can be encouraging, especially when it is supported by genuine business growth and manageable debt.
But there is an important caution.
A high ROE does not automatically mean that the company is financially strong.
Debt can influence ROE.
If a company has a relatively small equity base because it relies heavily on borrowing, its ROE can appear high. Therefore, investors should examine the company's debt position along with ROE.
EPS, P/E and ROE: What Does Each One Tell You?
The easiest way to remember these three measures is to give each one a simple question.
EPS asks:
"How much profit is being generated for each share?"
P/E asks:
"How is the current share price valued relative to earnings?"
ROE asks:
"How effectively is the company generating profit from shareholders' capital?"
In short:
EPS → Earnings
P/E → Valuation
ROE → Capital efficiency
These ratios look at different parts of the same business. That is why using them together can be more useful than relying on only one.
A Simple Example Using All Three
Suppose you are researching Company ABC.
The company has:
Share price: ₹300
EPS: ₹15
ROE: 18%
First, calculate the P/E:
₹300 ÷ ₹15 = 20
So, the company has:
- EPS of ₹15
- P/E of 20
- ROE of 18%
Are these numbers automatically good?
Not enough information is available to say.
You would still need to ask several questions.
Has the company's EPS increased over the past five years?
Is its profit growing?
How does its P/E compare with similar businesses?
Is the ROE consistently strong?
Does the company have excessive debt?
Is the business generating healthy cash flow?
What are the company's future growth opportunities?
These questions provide context around the ratios.
Common Mistakes Beginners Make
Looking Only at the P/E Ratio
Many new investors assume that a lower P/E always means a better opportunity.
That can be dangerous because a low valuation may exist for a valid reason.
Treating High ROE as a Guaranteed Positive
ROE needs to be considered along with debt and the company's overall financial structure.
Looking at Only One Year's EPS
A single year's earnings may be affected by unusual events. Looking at a longer period can provide a better understanding of the company's earnings pattern.
Comparing Unrelated Businesses
Different industries can have very different financial structures and valuation levels.
Comparing a bank directly with a manufacturing company using only P/E or ROE may not provide a meaningful conclusion.
Using Ratios as Automatic Buy or Sell Signals
Ratios are tools for research. They are not predictions.
A stock can have attractive financial ratios and still experience a decline in its market price.
How Beginners Can Use These Ratios
You do not need to study dozens of financial indicators when you are just starting.
A simple research process can be enough.
Start with the business. Understand what the company sells, who its customers are and how it makes money.
Check earnings. Look at revenue, profit and EPS over multiple years.
Study valuation. Compare the P/E with similar companies and the company's own historical valuation.
Examine ROE. Check whether the company has been generating reasonable returns on shareholders' equity.
Look at debt. A company's borrowing can have a major impact on its financial risk.
Review cash flow. Profit reported in financial statements and actual cash generated by the business are not always the same.
Read company disclosures. Annual reports, financial statements and official announcements can provide important information that ratios cannot show.
Final Thoughts
P/E Ratio, EPS, and ROE are not complicated concepts once you understand the question behind each number. EPS focuses on earnings per share, P/E connects the market price with those earnings, and ROE looks at how effectively shareholders' capital is being used to generate profit.
The important lesson for beginners is that no single ratio can explain an entire company. A low P/E does not automatically mean a stock is undervalued. A high ROE does not automatically mean a business is excellent. A rising EPS does not guarantee that the share price will rise.
The real value comes from putting these numbers together with the company's growth, debt, cash flow, competitive position, and future prospects. Over time, learning to interpret these figures rather than simply looking at them can make stock research much more meaningful.
