8 Financial Ratio Analysis that Every Stock Investor Should Know. The valuation of a company is a very tedious job. It’s not easy to evaluate the true worth of a company as the process takes the reading of company’s several years’ financial statements like balance sheet, profit and loss statements, cashflow statement, Income statement etc.
Although it really tough to go through all these information, however, there are various financial ratios available which can make the life of a stock investor really simple. Using these ratios they can choose right companies to invest in or to compare the financials of two companies to find out which one is better.
This post about ‘8 Financial Ratio Analysis that Every Stock Investor Should Know’ is divided into two parts. In the first part, I will give you the definitions and examples of these 8 financial ratios. In the second part, after financial ratio analysis, I will tell you how and where to find these ratios. So, be with me for the next 810 minutes to enhance your financial knowledge.
So, let’s start the first part of this post with the financial ratio analysis.
If you are a beginner and want to learn stock market, I will highly recommend you to read this book first: Everything You Wanted to Know About Stock Market Investing
Quick note: You don’t need to worry about how to calculate these ratios or remember the formulas byheart, as it will be already given in the financial websites. However, I will recommend you to go through this financial ratio analysis as it’s always beneficial to have good financial knowledge.
Financial Ratio Analysis that Every Stock Investor Should Know:

Earnings Per Share (EPS):
This is one of the key ratios and is really important to understand Earnings per share (EPS) before we study other ratios. EPS is basically the profit that a company has made over the last year divided by how many shares are on the market. Preferred shares are not included while calculating EPS.
Earnings Per Share (EPS) = (Net income – dividends from preferred stock)/(Average outstanding shares)
From the perspective of an investor, it’s always better to invest in a company with higher EPS as it means that the company is generating greater profits. Also, before investing in a company, you should check it’s EPS for the last 5 years. If the EPS is growing for these years, it’s a good sign and if the EPS is regularly falling or is erratic, then you should start searching another company.

Price to Earnings Ratio (P/E)
The Price to Earnings ratio is one of the most widely used financial ratio analysis among the investors for a very long time. A high P/E ratio generally shows that the investor is paying more for the share. As a thumb rule, a low P/E ratio is preferred while buying a stock, but the definition of ‘low’ varies from industries to industries. So, different sectors (Ex Automobile, Banks etc) have different P/E ratios for the companies in their sector, and comparing the P/E ratio of the company of one sector with P/E ratio of the company of another sector will be insignificant. However, you can use P/E ratio to compare the companies in the same sector, preferring one with low P/E. The P/E ratio is calculated using this formula:
Price to Earnings Ratio= (Price Per Share)/( Earnings Per Share)
It’s easier to find the find the price of the share as you can find it at the current closing stock price. For the earning per share, we can have either trailing EPS (earnings per share based on the past 12 months) or Forward EPS (Estimated basic earnings per share based on a forward 12month projection. It’s easier to find the trailing EPS as we already have the result of the past 12 month’s performance of the company.

Price to Book Ratio (P/B)
Price to Book Ratio (P/B) is calculated by dividing the current price of the stock by the latest quarter’s book value per share. P/B ratio is an indication of how much shareholders are paying for the net assets of a company. Generally, a lower P/B ratio could mean that the stock is undervalued, but again the definition of lower varies from sector to sector.
Price to Book Ratio = (Price per Share)/( Book Value per Share)

Debt to Equity Ratio
The debttoequity ratio measures the relationship between the amount of capital that has been borrowed (i.e. debt) and the amount of capital contributed by shareholders (i.e. equity). Generally, as a firm’s debttoequity ratio increases, it becomes riskier A lower debttoequity number means that a company is using less leverage and has a stronger equity position.
Debt to Equity Ratio =(Total Liabilities)/(Total Shareholder Equity)
As a thumb of rule, companies with a debttoequity ratio more than 1 are risky and should be considered carefully before investing.

Return on Equity (ROE)
Return on equity (ROE) is the amount of net income returned as a percentage of shareholders equity. ROE measures a corporation’s profitability by revealing how much profit a company generates with the money shareholders has invested. In other words, ROE tells you how good a company is at rewarding its shareholders for their investment.
Return on Equity = (Net Income)/(Average Stockholder Equity)
As a thumb rule, always invest in a company with ROE greater than 20% for at least last 3 years. A yearly increase in ROE is also a good sign.

Price to Sales Ratio (P/S)
The stock’s price/sales ratio (P/S) ratio measures the price of a company’s stock against its annual sales. P/S ratio is another stock valuation indicator similar to the P/E ratio.
Price to Sales Ratio = (Price per Share)/(Annual Sales Per Share)
The P/S ratio is a great tool because sales figures are considered to be relatively reliable while other income statement items, like earnings, can be easily manipulated by using different accounting rules.

Current Ratio
The current ratio is a key financial ratio for evaluating a company’s liquidity. It measures the proportion of current assets available to cover current liabilities. It is a company’s ability to pay its shortterm liabilities with its shortterm assets. If the ratio is over 1.0, the firm has more shortterm assets than shortterm debts. But if the current ratio is less than 1.0, the opposite is true and the company could be vulnerable
Current Ratio = (Current Assets)/(Current Liabilities)
As a thumb rule, always invest in a company with a current ratio greater than 1.

Dividend Yield
A stock’s dividend yield is calculated as the company’s annual cash dividend per share divided by the current price of the stock and is expressed in annual percentage.
Dividend Yield = (Dividend per Share)/(Price per Share)*100
For Example, If the share price of a company is Rs 100 and it is giving a dividend of Rs 10, then the dividend yield will be 10%. It totally depends on the investor whether he wants to invest in a high or a low dividend yielding company.

Hi Kritesh,
I am a beginner to stock market investment.
I felt this is a best place for beginner to understand how to start investing in stock market. All you articles in traders.in are informative and very easy to understand for a beginner.
Just have few queries related to above article.
I understood what is P/B and P/S, but could not get significance of a same in selecting a stock. Could you please help me out on the same?
Hi. A lower P/B ratio means that the stock is undervalued. Similarly, A low P/S ratio may indicate possible undervaluation, while a ratio that is significantly above the average may suggest overvaluation. You can read more here: http://www.investopedia.com/terms/p/pricetobookratio.asp
Hi Kritesh.
I have one doubt. Suppose if we calculate the value of a particular stock using the 8 financial ratio and found that a stock is good, then how long will that stock stay in that condition. (i.e) the validity of the ratio analysis of that particular stock.
Hi Selvaganapathi! Great question. You have to continously monitor the stock by tracking the quaterly results of the company once you have bought. It won’t be that tough as it will require just few hours every quater. If the fundamentals of the company continue to detoriate, say the EPS is falling for next 2 quaters without any understandable reason quoted by the management, then you might need to reconsider about holding that stock for long.
I am beginner to share market I think ur information given me basic foundation.

You are welcome Ashish.
Hey! I’m in 11th standard and I don’t know much about share market but I find it very interesting and I’m trying to learn about it. The article was really informative and helpful. Thank you so much.
Could you please explain what’s adv index. It’d be a great help. Thanks!
Moreover, what’s s&p and what it has to do with India?
Hi Prachi. Glad the article was useful to you. An advanced index is a tool that represents the total difference between the number of advancing and declining stock prices. It can provide much more insight into the movements of the market that the market Index. You can read more here. S&P stands for standards and poor and The S&P BSE SENSEX, also called the BSE 30 or SENSEX, is a freefloat marketweighted stock market index of 30 wellestablished and financially sound companies listed on Bombay Stock Exchange.It’s similar to the S&P 500 of NASDAQ. I hope this is helpful. Do lemme know if you have any other doubts and Keep learning.
That was fast. Oh, so s&p is another name for BSE! I get it.
Yeah, it was really helpful. Thanks a ton. And I’ll let you know if I have any other doubts. 🙂
Though, it may sound lame but I’m just curious to know that who calculates all this? I mean there must be an in charge of stock exchanges. And people working on it. Do you have any idea about it? Is it a good field?
SEBI (Securities exchange board of India) regulates the stock exchange in India and Yes, it’s a very interesting field.
All right. Thank you!
I’ll look into it.
Hi Kritesh
Your article is very helpful.I have two queries.Could you please on this
query1:
1)Could you please https://www.screener.in/ query for this 8 parameters
Earnings Per Share (EPS) – Increasing for last 5 years
Price to Earnings Ratio (P/E) – Low compared to companies in same sector
Price to Book Ratio (P/B) – Low compared companies in same sector
Debt to Equity Ratio – Should be less than 1
Return on Equity (ROE) – Should be greater that 20%
Price to Sales Ratio (P/S) – Smaller ratio (less than 1) is preferred
Current Ratio – Should be greater than 1
query2:
Regarding EPS which one we need to consider from money control?
1)Basic EPS or Diluted EPS or Cash EPS or something else?
2)Regarding ROE which one we need to consider from money control?
Return on Networth / Equity (%) or something else?
1) You can run most of these criteria on the screener. I have explained it in details here. However, there is no universal query. You have to make 23 itineraries to find the best stocks. For few of them, you have to check individually. For example, low PE is preferable, but what is low, it depends on the industry. You have to check the PEs with the competitors and industry.
2) In general, check the basic EPS (unless the company has convertible securities like convertible bonds or preferred stocks). Further, RONW us same to ROE. I hope it helps.
Hi Kritesh. I am new to stock market. i think i am getting answers to all my basic questions on ur website. so i am slowly nibbling at the information u have uploaded. it is worth appreciating ur efforts of sharing knowledge to others. u do good .. good will come back to u.

The article is is written is a simple language and easy to understand. Many investors place emphasis on Return on capital employed (ROCE) and Cash Flowand treat them as most important . If you can cover those ratios , we can benefit from your presentation.
Hi Vasudev. I have covered other ratios in details here: #19 Most Important Financial Ratios for Investors. I hope it helps. Cheers!
