Author: Tilak J. Balamurugan

Introduction: In the world of financial analysis, the P/E ratio is a fundamental metric used to evaluate a company’s valuation. While the basic P/E ratio provides a quick snapshot, advanced methods offer deeper insights into a company's performance and prospects. Whether you’re a seasoned investor or just getting started, understanding these advanced P/E ratio calculations and their combinations can significantly enhance your investment strategies. Dive into this guide to discover advanced methods and learn how to apply them effectively using real examples from Nifty50 stocks.

1. Forward P/E Ratio

Formula:

Forward P/E Ratio = Current Share Price / Expected EPS (for the next 12 months)

Concept: Uses projected earnings for the next 12 months, reflecting anticipated performance.

Parameters:

• Current Share Price: The latest trading price of the stock.
• Expected EPS: Projected earnings per share for the next 12 months.

Example Calculation (using Infosys Ltd):

Current Share Price (₹)	Expected EPS (₹)	Forward P/E Ratio
₹1,600	₹80	20

Calculation:

Forward P/E Ratio = ₹1,600 / ₹80 = 20

A Forward P/E Ratio of 20 indicates that investors are willing to pay ₹20 for every ₹1 of expected earnings in the next year.

Use Case: Ideal for growth companies where past earnings may not accurately represent future performance.

2. Trailing Twelve Months (TTM) P/E Ratio

Formula:

TTM P/E Ratio = Current Share Price / EPS (last 12 months)

Concept: Uses earnings from the past 12 months to provide a view based on historical performance.

Parameters:

• Current Share Price: The latest trading price of the stock.
• EPS (Last 12 Months): Earnings per share for the most recent 12-month period.

Example Calculation (using Tata Consultancy Services - TCS):

Current Share Price (₹)	EPS (Last 12 Months) (₹)	TTM P/E Ratio
₹3,400	₹170	20

Calculation:

TTM P/E Ratio = ₹3,400 / ₹170 = 20

A TTM P/E Ratio of 20 means investors are paying ₹20 for every ₹1 of past earnings.

Use Case: Best for stable companies where past performance is a reliable indicator of value.

3. PEG Ratio (Price/Earnings to Growth Ratio)

Formula:

PEG Ratio = P/E Ratio / Annual EPS Growth Rate

Concept: Adjusts the P/E ratio by the expected growth rate of earnings.

Parameters:

• P/E Ratio: Price-to-Earnings ratio.
• Annual EPS Growth Rate: Expected growth rate of earnings per share, expressed as a decimal.

Example Calculation (using HDFC Bank Ltd):

P/E Ratio	Annual EPS Growth Rate	PEG Ratio
22	15% or 0.15	1.47

Calculation:

PEG Ratio = 22 / 0.15 = 146.67

A PEG Ratio of 1.47 indicates that the P/E ratio is 1.47 times the expected growth rate.

Use Case: Useful for comparing companies with different growth rates, providing insight into valuation relative to growth.

4. Normalized P/E Ratio

Formula:

Normalized P/E Ratio = Current Share Price / Normalized EPS

Concept: Adjusts EPS to smooth out anomalies and provide a more stable earnings measure.

Parameters:

• Current Share Price: The latest trading price of the stock.
• Normalized EPS: Adjusted EPS to remove irregularities.

Example Calculation (using Reliance Industries):

Current Share Price (₹)	Normalized EPS (₹)	Normalized P/E Ratio
₹2,300	₹115	20

Calculation:

Normalized P/E Ratio = ₹2,300 / ₹115 = 20

A Normalized P/E Ratio of 20 provides a stable measure by adjusting for unusual earnings spikes.

Use Case: Best for companies with fluctuating earnings to get a clearer picture of long-term value.

5. Adjusted P/E Ratio

Formula:

Adjusted P/E Ratio = Current Share Price / Adjusted EPS

Concept: Modifies EPS to account for significant one-time events or changes in accounting policies.

Parameters:

• Current Share Price: The latest trading price of the stock.
• Adjusted EPS: EPS adjusted for non-recurring items or accounting changes.

Example Calculation (using Bharti Airtel Ltd):

Current Share Price (₹)	Adjusted EPS (₹)	Adjusted P/E Ratio
₹820	₹41	20

Calculation:

Adjusted P/E Ratio = ₹820 / ₹41 = 20

An Adjusted P/E Ratio of 20 accounts for unusual or one-time impacts on earnings.

Use Case: Provides a clearer valuation by adjusting for non-recurring items or changes in accounting methods.

6. CAPE Ratio (Cyclically Adjusted Price-to-Earnings Ratio)

Formula:

CAPE Ratio = Current Share Price / Average EPS (last 10 years)

Concept: Uses a 10-year average EPS to account for economic cycles and provide a long-term valuation measure.

Parameters:

• Current Share Price: The latest trading price of the stock.
• Average EPS: Average earnings per share over the last 10 years.

Example Calculation (using ICICI Bank Ltd):

Current Share Price (₹)	Average EPS (₹)	CAPE Ratio
₹400	₹20	20

Calculation:

CAPE Ratio = ₹400 / ₹20 = 20

A CAPE Ratio of 20 indicates a valuation relative to the average earnings over a decade, smoothing out cyclical effects.

Use Case: Useful for understanding long-term valuations and comparisons across different market conditions.

Comparison of P/E Ratios

Each P/E ratio variant has its unique advantages and applications:

• Forward P/E: Best for anticipating future performance.
• TTM P/E: Reflects historical performance, useful for stable companies.
• PEG Ratio: Adjusts for growth, making it ideal for comparing growth stocks.
• Normalized P/E: Provides stability by adjusting for irregularities.
• Adjusted P/E: Accounts for non-recurring items or accounting changes.
• CAPE Ratio: Offers long-term perspective by averaging earnings over a decade.

Consider these methods in combination to gain a comprehensive understanding of a company’s valuation.
