Price to Earning Ratio: How Does it Work

The PE ratio offers insights into a company’s earnings performance. Here is an overview of its various components:

  • Earnings Per Share (EPS): EPS is the portion of a company’s profit allocated to each outstanding share of common stock. It is calculated by dividing a company’s profit by the outstanding shares of common stock. It is used to estimate the corporate value and is also an indicator of the money that is made for each share. 
  • Interpreting PE Ratio: The Price to Earning ratio is calculated by dividing the current market price of a company’s stock by its EPS. It is a popular valuation metric of stocks and an indicator of expensiveness or cheapness of stock at its current market price.
  • Reading the Digits: A high PE ratio indicates that investors are willing to pay a premium for the company’s earnings, implying that the stock may be overvalued. Conversely, a low PE ratio suggests that the stock may be undervalued, as investors are paying less for each rupee of earnings.

Significance of PE Ratio

  • Fair Valuation: The PE ratio is used to assess whether a stock’s current market price accurately reflects its earnings potential. Therefore, the it is an indicator whether the stock’s current price is expensive or cheap. 
  • Comparative Analysis: It allows you to compare the valuation of different companies within the same industry or sector. By analyzing PE ratios, you can uncover which stocks are relatively expensive and which offer a more favorable pricing.

Price to Earning Ratio: Common Types

Now that we’ve clearly answered the question, “What is the PE ratio?”, let’s explore its various types that offer nuanced insights into a company’s valuation and earnings potential.

  • Trailing PE Ratio: This ratio provides crucial information about the company’s valuation, based on the data of the past one year. You can use this information to evaluate how the company’s valuation has been in the recent months. It is calculated by dividing the current market price of a stock by its EPS of the past 12 months. 
  • Forward PE Ratio: Unlike the trailing PE ratio, it takes into consideration the estimated future EPS. It divides the current market price by the projected EPS for the next 12 months. Forward ratio is valuable for gauging how the market values a company’s future earnings potential. You can use this information to asses how a company’s valuation is expected to be in the coming months.
  • Shiller PE Ratio (CAPE Ratio): Named after economist Robert Shiller, the CAPE ratio, or the Shiller PE ratio, considers the average earnings of a company over the past decade. It also considers the inflation over this time period. This ratio provides a long-term understanding of a company’s valuation.  
  • PEG Ratio (Price-to-Earnings Growth): The PEG ratio marries the PE ratio with a company’s projected earnings growth rate. It divides the PE ratio by the expected earnings growth rate. A PEG ratio less than 1 suggests that a stock might be undervalued relative to its growth prospects. The PEG ratio considers growth, making it suitable for investors interested in a company’s future potential.
  • Sector-Specific PE Ratios: Different industries exhibit distinct growth rates, risk profiles, and earning potential. Comparing a company’s PE ratio to the average PE ratio of its sector can provide a sense of how it stacks up against its peers. Comparing a company’s PE ratio to its industry average helps you contextualize its valuation within its sector.

Each type offers a unique perspective on a company’s valuation. By using these variations in conjunction, you can gain a more comprehensive understanding of a company’s financial health and investment potential.

Limitations of PE Ratios

While PE ratios offer valuable insights into a company’s valuation, it’s important to acknowledge their limitations. Like any other financial metric, it has some areas where their effectiveness may be diminished. Here are some limitations to keep in mind when interpreting and utilising trailing and forward PE ratios:

  • Earnings Volatility: Trailing PE ratios rely on historical earnings, which might not accurately represent a company’s future performance. If a company’s earnings have been exceptionally volatile due to industry fluctuations or one-time events, the trailing ratio might not provide a reliable assessment of its valuation.

To mitigate this, you can consider using multiple years of trailing earnings to smooth out any anomalies and provide a more accurate representation of the company’s earning power.

  • Earnings Quality: Not all earnings are created equal. Companies can manipulate their earnings through accounting practices, potentially skewing the PE ratio. One-time gains, write-offs, or changes in accounting methods can distort the true earnings picture.

Therefore, you should look beyond the PE ratio and analyse the company’s financial statements in more detail to assess the quality and sustainability of its earnings.

  • Limited Predictive Power: While the forward PE ratio attempts to incorporate future earnings, it relies on analysts’ estimates, which can be subject to biases and errors. Unexpected changes in a company’s future performance can render the forward PE ratio less accurate.

As a way to balance this out, you can choose to combine the forward PE ratio with other valuation metrics and conduct thorough research to validate the accuracy of earnings estimates.

  • Industry Variability: Different industries have different growth rates and risk profiles. Comparing PE ratios across sectors might not provide an apples-to-apples comparison, as some industries naturally command higher valuations.

When comparing this ratios, focus on companies within the same industry to ensure a more relevant benchmark.

  • Market Sentiment: PE ratios are influenced by market sentiment and investor psychology. A popular stock might have an inflated PE ratio due to high demand, even if its fundamentals don’t justify the valuation.

So, consider using it in conjunction with other valuation tools, such as price-to-book ratio or discounted cash flow analysis, to gain a more comprehensive perspective.

In Conclusion

As you navigate the intricate terrain of the share market, the PE ratio emerges as a guiding light that reveals the relationship between a company’s stock price and its earnings. By grasping the essence of PE, you can empower yourself to make informed investment choices. There are several types of PE ratios, as discussed in the article, and each one of them provide important assessments.

Remember, this ratio is not a standalone indicator of absolute truth. Different industries have varying PE norms. What’s considered high for one sector might be standard for another. So, to get the best results, blend it with comprehensive research, industry analysis, and a holistic understanding of a company’s financial health.
