The Price Earnings Ratio (P/E Ratio) is the relationship between a company’s stock price and earnings per share (EPS)Earnings Per Share Formula (EPS)The Earnings Per Share formula is a financial ratio, which counts net earnings against the total outstanding shares over a fixed period of time. A higher EPS ratio indicates a company’s ability to generate profits for common shareholders.. It is a popular ratio that gives investors a better sense of the valueFair ValueFair value refers to the actual value of an asset - a product, stock, or security - that is agreed upon by both the seller and the buyer. Fair value is applicable to a product that is sold or traded in the market where it belongs or in normal conditions - and not to one that is being liquidated. of the company. The P/E ratio shows the expectations of the market and is the price you must pay per unit of current earningsNet IncomeNet Income is a key line item, not only in the income statement, but in all three core financial statements.

Earnings are important when valuing a company’s stock because investors want to know how profitable a company is and how profitableProfit MarginIn accounting and finance, profit margin is a measure of a company's earnings relative to its revenue. The three main profit margin metrics are gross profit (total revenue minus cost of goods sold (COGS) ), operating profit (revenue minus COGS and operating expenses), and net profit (revenue minus all expenses) it will be in the future. Furthermore, if the company doesn’t grow and the current level of earnings remains constant, the P/E can be interpreted as the number of years it will take for the company to pay back the amount paid for each share.
Looking at the P/E of a stock tells you very little about it, if it’s not compared to the company’s historical P/E or the competitor’s P/E from the same industry. It’s not easy to conclude whether a stock with a P/E of 10x is a bargain, or a P/E of 50x is expensive without performing any comparisons.
The beauty of the P/E ratio is that it standardizes stocksStockWhat is a stock? An individual who owns stock in a company is called a shareholder and is eligible to claim part of the company’s residual assets and earnings (should the company ever be dissolved). The terms "stock", "shares", and "equity" are used interchangeably. of different prices and earnings levels.
The P/E is also called an earnings multiple. There are two types of P/E: trailing and forward. The former is based on previous periods of earnings per share, while a leading or forward P/E ratioForward P/E RatioThe Forward P/E ratio divides the current share price by the estimated future (“forward”) earnings per share (EPS).

R = Required Rate of Return
G = Sustainable Growth Rate

The basic P/E formula takes current stock price and EPS to find the current P/E. EPS is found by taking earnings from the last twelve months divided by the weighted average shares outstandingWeighted Average Shares OutstandingWeighted average shares outstanding refers to the number of shares of a company calculated after adjusting for changes in the share capital over a reporting period.

High P/E
Companies with a high Price Earnings Ratio are often considered to be growth stocks. This indicates a positive future performance, and investors have higher expectations for future earnings growth and are willing to pay more for them. The downside to this is that growth stocks are often higher in volatility and this puts a lot of pressure on companies to do more to justify their higher valuation. For this reason, investing in growth stocks will more likely to be seen as a riskyRisk AversionRisk aversion refers to the tendency of an economic agent to strictly prefer certainty to uncertainty. An economic agent exhibiting risk aversion is said to be risk averse. Formally, a risk averse agent strictly prefers the expected value of a gamble to the gamble itself. investment. Stocks with high P/E ratios can also be considered overvalued.
Low P/E
Companies with a low Price Earnings Ratio are often considered to be value stocks. It means they are undervalued because their stock price trade lower relative to its fundamentals. This mispricing will be a great bargain and will prompt investors to buy the stock before the market corrects it. And when it does, investors make a profit as a result of a higher stock price. Examples of low P/E stocks can be found in mature industries that pay a steady rate of dividendsDividendA dividend is the share of profits a shareholder receives, made on behalf of the corporation. When a company genearates a profit and accumulates retained earnings, those earnings can be either reinvested in the business or paid out to shareholders as a dividend. Types include: cash, common, preferred, stock, property.
P/E Ratio Example
If Stock A is trading at $30 and Stock B at $20, Stock A is not necessarily more expensive. The P/E ratio can help us determine from a valuation perspective which of the two is cheaper.
If the sector’s average P/E is 15, Stock A has a P/E = 15 and Stock B has a P/E = 30, stock A is cheaper despite having a higher absolute price than Stock B, because you pay less for every $1 of current earnings. However, Stock B has a higher ratio than both its competitor and the sector. This might mean that investors will expect higher earnings growth in the future relative to the market. The P/E ratio is just one of the many valuation measures and financial analysis tools that we use to guide us in our investment decision, and it shouldn’t be the only one.

Limitations of Price Earnings Ratio
Finding the true value of a stock cannot just be calculated using current year earnings. The value depends on all expected future cash flowsCash FlowCash Flow (CF) is the increase or decrease in the amount of money a business, institution, or individual has. In finance, the term is used to describe the amount of cash (currency) that is generated or consumed in a given time period. There are many types of CF and earnings of a company. Price Earnings Ratio is used as a good starting point. It means little just by itself unless we have some understanding of the growth prospects in EPS and risk profile of the company. An investor must dig deeper into the company’s financial statementsThree Financial StatementsThe three financial statements are the income statement, the balance sheet, and the statement of cash flows. These three core statements are intricately linked to each other and this guide will explain how they all fit together. By following the steps below you'll be able to connect the three statements on your own. and use other valuation and financial analysis methodsTypes of Financial AnalysisFinancial analysis involves using financial data to assess a company’s performance and make recommendations about how it can improve going forward. Financial Analysts primarily carry out their work in Excel, using a spreadsheet to analyze historical data and make projections Types of Financial Analysis to get a better picture of a company’s value and performance.
Additionally, the Price Earnings Ratio can produce wonky results as demonstrated below. Negative EPS resulting from a loss in earnings will produce a negative P/E. An exceedingly high P/E can be generated by a company with close to zero net income, resulting in a very low EPS in the decimals.
