Stock Fundamental Analysis - A Simple Guide

What is Fundamental Analysis?

Think of it like checking a car before buying it. You look under the hood, check the mileage, see if there's any damage. Fundamental analysis is the same thing, but for companies.

You look at a company's money situation - how much it earns, how much it owes, and whether it's growing. If the numbers look healthy, the stock is probably a decent buy. If not, you might want to stay away.

Key Parameters (The Numbers That Matter)

P/E Ratio (Price to Earnings)

How many years of profits you're paying for

P/E Ratio = Stock Price / Earnings Per Share (EPS)

Explanation: If a stock costs 450 and earns 30 per share per year, you're paying 15 years worth of earnings. Think of it like buying a business - a P/E of 15 means it takes 15 years of profits to get your money back (if everything stays the same).

P/E ratio comparison showing what different values mean

Good: Below 20 for most industries. Means the stock isn't overpriced.

Bad: Above 40-50. You might be paying too much for what the company earns.

P/B Ratio (Price to Book Value)

Are you paying more than the company is actually worth on paper?

P/B Ratio = Stock Price / Book Value Per Share

Explanation: Book value is like the net worth of a company (what it owns minus what it owes, divided by total shares). If P/B is 2, you're paying double what the company is worth on paper. Below 1 means you're getting a discount.

Good: Below 3. Ideally close to 1 or less for value stocks.

Bad: Above 5. You're paying a big premium over actual assets.

Debt to Equity Ratio

How much the company has borrowed compared to what it owns

Debt to Equity = Total Debt / Total Equity

Explanation: Imagine you bought a house worth 50 lakhs but took a loan of 30 lakhs. Your debt-to-equity is 30/20 = 1.5. For companies, lower is safer. A company with too much debt can get into trouble if business slows down.

Debt to Equity comparison showing risky vs healthy vs safe companies

Good: Below 1. Company owns more than it owes.

Bad: Above 2. Too much borrowing - risky if business slows.

Return on Equity (ROE)

How good is the company at making money with shareholders' investment?

ROE = (Net Profit / Shareholders' Equity) x 100

Explanation: If you gave 100 to a friend's business and they made 25 profit from it, their ROE is 25%. Higher ROE means the company is really good at turning your investment into profit.

Good: Above 15%. Company is using money efficiently.

Bad: Below 10%. Company isn't great at making profits from its resources.

Earnings Per Share (EPS)

How much profit does each share earn?

EPS = Net Profit / Total Number of Shares

Explanation: If a company made 100 crore profit and has 10 crore shares, each share earned 10. Higher EPS means the company is earning more money for each share you own. You want this number to grow every year.

Good: Growing consistently year after year. Higher is better.

Bad: Falling or negative. Company is earning less or losing money.

Revenue Growth (Year over Year)

Is the company selling more stuff than last year?

Revenue Growth = ((This Year Revenue - Last Year Revenue) / Last Year Revenue) x 100

Explanation: If a shop made 10 lakhs last year and 12 lakhs this year, it grew by 20%. Growing revenue means more customers or higher sales. A company that's not growing might be in trouble.

Good: Above 10-15% per year. Company is expanding well.

Bad: Negative or flat. Business is shrinking or stuck.

Dividend Yield

How much cash do you get back each year just for holding the stock?

Dividend Yield = (Dividend Per Share / Stock Price) x 100

Explanation: Some companies share their profits with shareholders as cash dividends. If you buy a stock at 450 and get 10 back each year as dividend, your yield is about 2.2%. It's like getting interest on a fixed deposit, but from a company.

Good: 2-6%. Regular payouts show the company is profitable and generous.

Bad: 0% or unreliable. Company either isn't profitable or keeps all profit.

Promoter Holding

How much of the company do the founders/owners still own?

Promoter Holding = (Shares held by promoters / Total shares) x 100

Explanation: Promoters are the people who started or control the company. If they own a big chunk (50%+), it usually means they believe in their own company. If they're selling their shares, it might be a red flag - would you stay on a ship the captain is leaving?

Good: Above 50%. Owners have skin in the game.

Bad: Below 30% or constantly decreasing. Owners may be losing confidence.

Grading a Stock - Example

ABC Industries - Report Card

Let's calculate each number for a dummy company and give it a grade, just like in school.

Company Data
Stock Price	₹450
EPS	₹30
Book Value per Share	₹200
Total Debt	₹500 Cr
Total Equity	₹800 Cr
Net Profit	₹200 Cr
Revenue (this year)	₹2000 Cr
Revenue (last year)	₹1700 Cr
Dividend per Share	₹10
Promoter Holding	62%

Calculations & Grades:

P/E Ratio: 450 / 30 = 15 (Below 20 - good!) → Grade: A

P/B Ratio: 450 / 200 = 2.25 (Below 3 - decent) → Grade: B

Debt to Equity: 500 / 800 = 0.625 (Below 1 - great!) → Grade: A

ROE: (200 / 800) x 100 = 25% (Above 15% - excellent!) → Grade: A

EPS: ₹30 (Positive and healthy) → Grade: B

Revenue Growth: ((2000 - 1700) / 1700) x 100 = 17.6% (Above 15% - strong!) → Grade: A

Dividend Yield: (10 / 450) x 100 = 2.2% (Decent payout) → Grade: B

Promoter Holding: 62% (Above 50% - owners believe in it) → Grade: A

How to Use This

Simple rule: Before buying any stock, check these numbers. If most parameters show A or B grade, the company is financially strong. If you see mostly C or D, be careful.

No single number tells the full story. A company might have great ROE but too much debt. Always look at the full picture - all 8 parameters together. Also compare with other companies in the same industry (comparing a bank with an IT company doesn't make sense).

Check these numbers once every quarter (every 3 months) when companies release their results. If you see grades dropping over time, it might be time to reconsider your investment.
