When evaluating a company's value, investors mostly look at a stock's price-to-earnings (P/E) or price-to-sales (P/S) ratio. While P/E is the ratio of annual earnings to stock price, P/S reflects the amount investors pay for each dollar of revenues generated by the company. Though P/E and P/S valuation tools are more commonly used for stock selection, the price-to-book ratio (P/B ratio) is also an easy-to-use metric for identifying low-priced stocks with high-growth prospects.  P/B is the ratio of stock price to book value It is calculated as below: P/B ratio = market capitalization/book value of equity The P/B ratio helps to identify low-priced stocks with high growth prospects. ASE Technology (NYSE: ASX), Paysafe Limited (NYSE: PSFE), The ODP Corporation (NASDAQ: ODP), Deluxe (NYSE: DLX) and KB Home (NYSE: KBH) are some such stocks.

In other words, this is what shareholders would theoretically receive if a company liquidates all its assets after paying off all its liabilities. It is calculated by subtracting total liabilities from the total assets of a company. In most cases, this equates to common stockholders' equity on the balance sheet. However, depending on the company's balance sheet, intangible assets should also be subtracted from the total assets to determine book value. Understanding P/B Ratio By comparing the book value of equity to its market price, we get an idea of whether a company is under or overpriced. However, like P/E or P/S ratio, it is always better to compare P/B ratios within industries. A P/B ratio of less than one means that the stock is trading at less than its book value or the stock is undervalued and, therefore, a good buy. Conversely, a stock with a ratio greater than one can be interpreted as ...
