ⓘPrice-to-Earnings Ratio (P/E)
The P/E ratio divides National Grid's share price by its earnings per share. It tells you how many years of current earnings you are "paying for" when you buy the stock. A P/E of 20 means you pay $20 for every $1 of annual earnings. The S&P 500 historically trades at an average P/E of roughly 15–17. A P/E significantly above that may signal high growth expectations; one below may indicate undervaluation — or declining business quality.
Price-to-Sales Ratio (P/S)
The P/S ratio divides market capitalization by total revenue. Unlike the P/E ratio, it works even for companies that are not yet profitable, making it essential for evaluating high-growth firms. A P/S below 1.0 may indicate undervaluation, while ratios above 10 are typically reserved for fast-growing tech or SaaS companies with high expected future margins.
Price-to-EBIT Ratio
This ratio relates National Grid's market price to its operating earnings, excluding the effects of debt structure and tax jurisdiction. It is particularly useful for comparing companies across different countries or with different levels of leverage, because it focuses purely on operational profitability. Lower values suggest cheaper operational earnings.
How to Use This Chart
This chart plots National Grid's valuation multiples over time. Compare the current P/E, P/S, and P/EBIT to their own historical averages — if the current ratio is well below the multi-year average, the stock may be relatively cheap compared to its own track record. Combine this with industry comparisons: a P/E that looks high in absolute terms may be justified if National Grid grows earnings faster than its peers.

The price-earnings ratio (P/E ratio) is a key figure for evaluating a stock. The stock price is compared to the earnings per share. The ratio therefore expresses the number of years it takes for a company to generate the current earnings to match the stock price.
P/E ratio formula:
P/E ratio = Stock price / Earnings per Share (EPS)
If the earnings per share (EPS) is not readily available, it can be calculated by dividing the company's total earnings by the number of shares issued.
EPS formula:
Total earnings of the company / Number of shares issued
The earnings per share (EPS) can usually be easily found on most financial websites.
The P/E ratio is one of the most commonly used indicators for valuing stocks. However, the correct application of the P/E ratio is slightly more complicated than the formula described above would suggest. Therefore, it is always only a snapshot and not a reliable consideration of the future. If future earnings were to increase without any change in the stock price, the P/E ratio would accordingly decrease.

The P/E ratio in evaluating a stock.
The price-earnings ratio (P/E ratio) is an important financial ratio that is often used by investors to assess the attractiveness of a stock. It is an indicator of a company's earnings and valuation, and provides an indication of whether a stock is overvalued or undervalued. It is also used as an indicator of whether a stock is "expensive" or "cheap".
History of P/E ratio
The P/E ratio was first used in 1881 by the famous financial scientist Benjamin Graham. He developed the P/E ratio as a means to evaluate whether a stock is trading at a "good" or "bad" price. Since then, the P/E ratio has had a long history in the financial world, particularly among investors who are looking for a way to evaluate stocks in an informed manner.
Calculation of the P/E ratio
The P/E ratio is calculated by dividing the current stock price by the earnings per share. A simple formula for calculating the P/E ratio is as follows:
P/E ratio = Stock price / Earnings per share
Example: If a stock is traded at the current price of $10 and the earnings per share is $1, the P/E ratio would be 10 ($10 / $1 = 10).
Application of the P/E ratio
Investors use the P/E ratio to assess the attractiveness of a stock. A high P/E ratio can indicate that a stock is overvalued, while a low P/E ratio means that a stock is undervalued. Investors can then decide whether to buy, sell, or hold a stock based on this information. Another reason why investors use the P/E ratio is to check how stocks perform compared to other stocks or the market as a whole. If a stock's P/E ratio is higher than the overall market's P/E ratio, this may mean that the stock is overvalued, and investors can decide whether to sell or hold the stock. Investors usually also use the P/E ratio to compare stocks over time. If a stock has a P/E ratio of 10 and a year later has a P/E ratio of 20, this may mean that the stock is overvalued. Investors can then decide whether to hold or sell the stock.
Advantages and Disadvantages of using the P/E ratio
BenefitsThe P/E ratio is a useful tool to assess the attractiveness of a stock and to evaluate how a stock is performing compared to the market. It is a simple tool that can assist investors in deciding whether to buy, sell, or hold a stock.
DisadvantagesThe P/E ratio is a simple tool that does not provide any information about the future performance of a stock. It can be difficult to predict the future performance of a stock, and sometimes the P/E ratio can give a false picture of a stock. Therefore, investors must be cautious when relying on the P/E ratio.
In addition, the P/E ratio can vary depending on the industry, which makes comparability difficult. For example, a stock in a certain industry may have a low P/E ratio, while another stock in a different industry may have a higher P/E ratio. Therefore, investors must be cautious when relying on the P/E ratio.
Conclusion
The P/E ratio is a useful tool that can assist investors in assessing the attractiveness and value of a stock. It can also be used to check how a stock is performing in comparison to the market. However, it is important to note that it is a simple tool that does not make any statement about the future performance of a stock, and investors must be cautious when relying on the P/E ratio.
