Some investors may be wondering, between return on equity (ROE) and price earnings ratio (PER), which method is more suitable to value a company. According to John Neff, ROE is regarded as the best single measure of managerial performance because it shows the management’s ability to generate profit from the capital it employs. It is the ratio of net income to shareholders’ equity.
Warren Buffett said a good business should be able to achieve good ROE without employing high debts. Companies with high gearing are vulnerable to financial risk during the economic downturn and high interest rate environment. Besides, any future investment plans should be funded by internally generated cash flow without having to call on shareholders to contribute. Unless the return generated from the shareholders’ money is greater than ROE, it will show lower shareholders’ returns as a result of the enlarged share capital.
(A brief explanation to those without a financial background: Business can be run with 2 types of funding, Debts and Equity. Debts include loans from banks, leasing and etc and they carry fixed interest charges, regardless if the company is making money. So, in a bad time, when the company is not making much money and with margins squeezed, those with heavy debts are usually those to go down first. The US subprime crisis is an example of how deadly debts can be. Equity are also known as Capital or Shareholders' Fund, include Reserves, Retained Earnings and Paid Up Capital.)
A higher PER implies that it takes more years to get back your returns from the company’s earnings. Based on the academic view, a higher PER is better than a lower one because this implies that investors are willing to pay more than the normal market PER. Nevertheless, in practice, most analysts will say that a lower PER is better because it implies that the company is undervalued and cheap at the current valuation. So which view should we follow?
In an efficient market, companies that are selling at a higher PER are better than companies with a lower PER. This is because when the market is efficient, the current price will reflect past, current and future information.
In Malaysia however, most academic researchers have concluded that our stock market is not efficient, which implies that the current stock prices do not reflect all information. Hence, there may be some potential past or future information that is not fully reflected in a stock’s current price. Given this, it is quite possible to find some undervalued companies on Bursa Malaysia if we select those with low PERs.
First, we have to understand what causes a company stock to be sold at a low PER, where the market price is lower relative to its earnings. However, not all stocks with low PER imply good value for investing. As mentioned earlier, sometimes the cheap valuation may be a true reflection of certain negative aspects of the company, for example, poor corporate governance, high gearing, uncertainty of future earnings and or it is facing litigation. However, as a result of asymmetric information, not all investors are fully aware of the market’s worries. Hence, analysts with the necessary knowledge, skills and market information play a very critical role in helping investors to analyse companies in detail and identifying those that are truly undervalued based on fundamentals.
