How Is A High P/B Ratio Linked To A High Return On Equity?

Nov 14, 2023 By Susan Kelly

It is not always the case that a high return accompanies a high P/B ratio on equity (ROE), but in ideal conditions, it is. Investors provide preference to businesses that generate greater returns on equity; consequently, the market value of these businesses is increased as a direct result of this preference. For obvious reasons, a low price-to-book ratio is often associated with an unsatisfactory return on equity and return on assets (ROA).


The Computation Of P/B May Be Broken Down Into The Following Steps:


  • When examining the most current balance sheet of the firm, the amount of equity allocated to each share is calculated by dividing the total equity held by shareholders by the total number of shares in circulation.
  • An equity valuation that assesses profitability as a function of the amount of capital invested by shareholders is referred to as return on equity (ROE). Meanwhile, return on equity is a gauge of profit efficiency. Using this statistic, a percentage evaluation of the return on that equity investment may be determined.
  • Both the price-to-book ratio and the return on equity evaluation should be considered since both of these metrics consider the book value of equity. Since none of the tools used for valuation is foolproof, it is important to compare the results of one appraisal to those of another.
  • The price-to-book ratio (P/B) and return on equity (ROE) are ways to analyze a company, although they do so from somewhat different perspectives. However, they are connected in that both consider the book value of equity.


What You Should Look Out For In the Data


Because investors tend to pay greater multiples of book value for a company that gives them a solid return on their investment, a firm with a high P/B ratio often also has a proportionally high ROE. It is expected that the P/B ratios of companies experiencing rapid expansion will be high. IBM is a fantastic example of a case study that demonstrates ROE's impact on P/B ratios. In 1983, the company's stock was trading at three times its book value, and its ROE was 25%. In 1992, the ROE had dropped to negative levels, which caused the stock to trade at its book value.


If there is a significant disparity between the two measures—for instance, if the P/B ratio is high but the ROE is low—this may be an early warning that shareholder equity is no longer growing. The divergent positions taken by ROE and P/B point to the securities having an excessive price relative to their intrinsic worth. On the other hand, if the P/B ratio is low but the ROE is high, the securities are undervalued. When doing an evaluation, it may be prudent to combine the different measurements, such as P/B and ROE, to investigate how the numbers have changed over time.



The Definition and Function


The market value of a company's shares (share price) to its book value of equity is denoted by the notation "price-to-book value or P/B for short. The value of an organization's assets, as reported on the balance sheet, is used to calculate the book value of equity. The difference between the book value of assets and the book value of liabilities is meant when people talk about the "book value."


A Price-To-Book (P/B) Ratio


Investors may take note of a firm's P/B ratio if it has lower values, especially if the ratio falls below one; this may be a hint that the stock is cheap. In other words, the market price of the company's shares is now trading at a discount on the value of the company's assets. On the other hand, players in the market may believe that the company's asset worth is exaggerated. Because there is a possibility that the market will change the value of the company's assets, investors will likely avoid purchasing the company's shares if the company's assets are overvalued. This is because investors will then be left with negative returns on their investments.



A low P/B ratio might also indicate that the firm is receiving a very poor return on its assets (perhaps even a negative return) (ROA). Suppose the firm has a history of bad financial performance. In that case, there is a possibility that the company's prospects may improve under new management or as a result of changing business circumstances, which will result in substantial positive returns. A firm that is trading at a valuation that is lower than its book value has the potential to be split up for the value of its assets, which would result in a profit for the shareholders.
