PE Ratio (Price to Earnings): Meaning, Formula & Types

The Price-to-Earnings (P/E) ratio is a tool that shows how much investors are willing to pay today for one rupee of a company’s earnings. It’s calculated by dividing the current share price of a company by the earnings per share (EPS). P/E ratio in mutual funds refers to the weighted average P/E ratios of the underlying stocks in the fund’s portfolio. This ratio is often used to understand how expensive or reasonably priced a stock may be, especially when compared with similar companies or the broader market. However, the P/E ratio works best when used with other financial indicators, as it doesn’t reflect future growth, business risks, or industry differences on its own. Investors are advised to consider the P/E ratio alongside other factors such as earnings growth, sector allocation, and the fund’s overall investment strategy etc. to make well-informed decisions.

Key Takeaways

• The P/E ratio shows how much investors are willing to pay for each rupee of earnings per share.
• A higher P/E may indicate growth expectations, while a lower P/E may reflect lower growth or potential undervaluation.
• If a company is not profitable, a valid P/E ratio may not be available.
• There are two key types trailing P/E (based on historical earnings) and forward P/E (based on expected earnings).
• It is more effective when used to compare companies within the same industry or sector.
• The P/E ratio of a mutual fund is arrived at by taking the weighted average of the P/E ratios of the underlying stocks, based on their allocation within the fund’s portfolio

What is P/E Ratio in Mutual Fund?

The Price to Earnings (P/E) ratio is a commonly used valuation metric that helps investors understand how the market is pricing a company relative to its earnings. It compares the current market price of a company’s share to its earnings per share (EPS), providing a general idea of how expensive or reasonably priced the stock may be based on reported profits.

Investors often use the P/E ratio to compare companies within the same industry or to track how the valuation of a stock changes over time. It can also assist in evaluating equity oriented mutual fund investments by assessing the aggregate valuation of the underlying portfolio.

It also plays an important role when evaluating mutual fund investment choices that are equity heavy. While it offers insights into valuation and market sentiment, it should not be the sole factor in decision making.

Mutual fund portfolios also disclose a P/E ratio, which is typically derived as the weighted average of the P/E ratios of the underlying stocks based on their allocation in the portfolio. This figure provides a snapshot of the portfolio’s current valuation. However, it should not be viewed in isolation and must be interpreted in the context of the fund’s investment objective, sector exposure, and market conditions.

Price vs Earnings: Breaking Down the Components

The P/E ratio is made up of two simple elements price and earnings. The price refers to the current trading value of one share of a company. The earnings are the company’s profit for each share, usually calculated over the last 12 months.

By dividing the share price by the earnings per share (EPS), you get the P/E ratio. This number helps investors understand how the market is valuing the company’s profits. A higher P/E may indicate strong growth expectations, while a lower P/E could suggest undervaluation or concerns about future performance.

What is P/E Ratio Formula?

The Price to Earnings (P/E) ratio is calculated by dividing the current share price by the company’s earnings per share (EPS):

P/E Ratio = Share Price ÷ Earnings Per Share

To find the share price, you can simply check any financial website using the company’s stock symbol. The EPS tells you how much profit the company made for each share and can be based on past results or future estimates.

• If the EPS is based on the last 12 months, it’s called a trailing P/E.
• If it’s based on projected earnings, it’s called a forward P/E.

Both versions give insight into how the market is valuing the company either based on its recent performance or its expected growth.

If a stock is trading at ₹500 and its EPS is ₹10, its P/E ratio would be 50. This means investors are willing to pay ₹50 for every ₹1 the company earns.

Types of PE Ratios

1. Trailing vs Forward PE: Why They Differ

The trailing P/E ratio looks at a company’s earnings from the past 12 months. It’s based on actual results, so many investors trust it. But since it shows only past performance, it may not tell you how the company will do in the future. Also, stock prices keep changing, while earnings are updated only every few months so the number can get outdated quickly.

The forward P/E ratio, on the other hand, uses estimated earnings for the future. This can provide an estimate of how the market values the company based on anticipated performance. But since these are just predictions, they may not always be accurate.

2. Absolute PE vs Relative PE

Absolute P/E is the basic price to earnings ratio you usually see. It tells you how many times a company's current stock price is trading compared to its earnings per share (EPS). Depending on the data used, it can be based on past earnings (trailing), future estimates (forward), or a mix of both.

For example, if a company’s stock price is ₹100 and its earnings per share is ₹2, the absolute P/E would be 50.
Relative P/E, on the other hand, puts this number in context. It compares the current P/E to how the company or even the market has been valued in the past. For instance, if today’s P/E is 80% of the highest P/E seen in the last 10 years, it means the stock is currently valued lower than its historical peak. A relative P/E of 100% or more means today’s valuation is at or above past highs.

In short:

• Absolute P/E tells you the current valuation.
• Relative P/E tells you how that current valuation stacks up against past trends.

Interpreting PE: High, Low & "Good" Bands

There is no universally good P/E ratio.

• A higher P/E ratio may reflect investor optimism or expectations of future growth, but it could also imply greater valuation risk.
• A lower P/E ratio might suggest potential undervaluation or concerns regarding earnings outlook.

How Fund Level PE Is Calculated

The P/E ratio at the mutual fund level is generally calculated as the weighted average of the P/E ratios of the underlying stocks in the portfolio, based on their respective allocations. While this metric can provide an indicative view of the portfolio’s valuation, it should be interpreted in conjunction with other parameters such as the fund’s investment mandate, sector composition, and overall market context. It is not indicative of future performance.

Limitations of Using the P/E Ratio

• Although the P/E ratio is widely used to assess stock valuations, it does have some limitations.
• One key challenge comes up when a company isn’t profitable. If earnings are zero or negative, calculating the P/E in the standard way isn’t possible. Some analysts label it as not available while others assign a value of zero or even a negative number none of which provide a clear picture.
• Another drawback is that P/E ratios don’t translate well across industries. Different sectors operate at varying growth rates and follow different financial models, which affects how investors value them.
• To make the most of this metric, it’s best to compare P/E ratios between companies in the same sector. That ensures a fair and relevant comparison.

Conclusion

The P/E ratio is a valuable tool in evaluating stocks and mutual funds. While it offers insights into valuation and market sentiment, it should not be the sole factor in decision making. Combine it with other metrics like the Expense Ratio, Sharpe Ratio, and Information Ratio, along with qualitative analysis, for a well-rounded investment view.
