This fourth section of this serial treats the subject of the debt/equity ratio, another important part of the successful methodology used by Warren Buffett. As a matter of fact, it’s something that Buffett considers crucial when picking his stocks. Much like the return on equity that was explained in the third section of this serial, this ratio is commonly employed in the financial world, however, Buffett has the ability to use it in a way that nobody else does.

The components that make up the debt/equity ratio are fairly obvious and I’m certain that many people first heard of it in high school in a commerce or business class. But just in case, there’s still some confusion, I will give a quick, brief explanation. The debt/equity ratio is given by total liabilities of a company divided by shareholders’ equity.

Both total liabilities and shareholder’s equity can be found on a company’s balance sheet (sometimes known as the statement of financial position). This is known as taking its ‘book value’. On the other hand, if the concerned company’s debt and equity are publicly traded, you can use the market value instead. There is also the possibility of using a mixture of both the book and market value.

The ratio illustrates the proportion of debt and equity the company is utilising to support its assets. If a ratio is high, this corresponds to a situation where debt is mainly shoring up the company. The principal dilemma with a high ratio is that it renders earnings volatile and leaves it at the mercy of interest rates, which can be expensive.

In fact, Buffett takes the results of this ratio very seriously and it’s very educational to comprehend the reasons why. Like all investors, he wants a company to only possess a tiny quantity of debt and the reason why is that a tiny quantity of debt indicates that growth in income is being yielded from shareholders’ equity contrary to borrowed money. If a company utilises borrowed money to finance its income, this usually forms a vicious cycle of debt and repayments which is unstable and which is dependent on interest rates.

So the message to take from Buffett is to concentrate on companies which have a low ratio, or at least a low ratio compared with other companies in the same industry. This involves a bit of work from your part in trying to calculate the ratios for each company, but as I said earlier, the required information is freely available on company reports.

Many investors prefer to use long-term debt rather than the traditional component, total liabilites, when they are calculating the ratio. According to many, this could prove to be more effective and convenient due to the long term nature of stocks investing. Among these people, Buffett is one of them.

The final part of this series will focus on the left over element of Buffett’s methodology - profit margins, an underestimated concept in finance today. Keep your eye out for it!
