Stock Valuation - Price-to-earning/Book

caption text "How To Value Stocks? hashtag text "#PriceToEarningsComparison

Welcome back to our stock valuation series! In our last episode, we're exploring the Price-to-Earnings (P/E) & Price-to-book multiples, one of the most commonly used valuation metrics. Let's dive in!

Understanding P/E Multiples P/E multiples are based on company earnings, a.k.a. profit. You simply take the company in question’s share price and divide that by its earnings per share (EPS). You’ll come across two values: “trailing” P/E and “forward” P/E. The former uses historical earnings data, while the latter is based on analysts’ forecasts for future earnings. 📊

Using P/E Multiples A stock’s P/E is largely useless by itself: you need to compare it to similar companies or the relevant sector average. However, be wary when comparing P/E multiples. For one thing, P/E can present companies with lots of debt as automatically more expensive than companies with less. You should therefore look up how much a company pays in interest when assessing its P/E – as well as its tax liabilities, which can have the same effect.

Limitations of P/E Multiples That’s the problem with P/E: it doesn’t tell you why something has the multiple it does. A relatively low P/E could mean that a stock is cheap – or simply that forecasts appear too high. Figuring out which is the case is tricky: you can get a sense of what’s going on by doing your own research on the company, but only time will tell.

Price-to-Book (P/B) Ratios Apart from P/E ratios, another valuation metric to consider is the Price-to-Book (P/B) ratio. This ratio compares a company's market value to its book value, which is the value of its assets minus liabilities. P/B ratios are particularly useful for companies with significant tangible assets, such as those in the banking and real estate sectors. However, it's important to consider other factors and not rely solely on the P/B ratio for valuation. 🏦

A P/B ratio less than 1 might indicate an undervalued stock, while a P/B ratio greater than 1 could suggest an overvalued stock. However, it's important to consider other factors and not rely solely on the P/B ratio for valuation. To get a comprehensive understanding of a company's valuation, it's essential to consider various factors, including growth prospects, competitive position, and cash flow generation. Valuation methods like P/E and P/B ratios should be used in conjunction to provide a more accurate picture of a company's true value.


P/E lets you make handy comparisons between companies and industries – but like all valuation methods, it’s only as good as what you put in. Each valuation methodology has its pluses and minuses, but none are a replacement for diving into a company’s fundamentals to understand how it’ll perform in the future. 💡
