What can financial ratios tell us?

30 มี.ค. 2023

In the previous post we learned what financial ratios are. These are ratios of various indicators from financial statements that help us draw conclusions about the fundamental strength of a company and its investment attractiveness. In the same post, I listed the financial ratios that I use in my strategy, with formulas for their calculations.

Now let's take apart each of them and try to understand what they can tell us.

- Diluted EPS. Some time ago I have already told about the essence of this indicator. I would like to add that this is the most influential indicator on the stock market. Financial analysts of investment companies literally compete in forecasts, what will be EPS in forthcoming reports of the company. If they agree that EPS will be positive, but what actually happens is that it is negative, the stock price may fall quite dramatically. Conversely, if EPS comes out above expectations - the stock is likely to rise strongly during the coverage period.

- Price to Diluted EPS ratio. This is perhaps the best-known financial ratio for evaluating a company's investment appeal. It gives you an idea of how many years your investment in a stock will pay off if the current EPS is maintained. I have a particular take on this ratio, so I plan to devote a separate publication to it.

- Gross margin, %. This is the size of the markup to the cost of the company's product (service) or, in other words, margin. It is impossible to say that small margin is bad, and large - good. Different companies may have different margins. Some sell millions of products by small margins and some sell thousands by large margins. And both of those companies may have the same gross margins. However, my preference is for those companies whose margins grow over time. This means that either the prices of the company's products (services) are going up, or the company is cutting production costs.

- Operating expense ratio. This ratio is a great indicator of management's ability to manage a company's expenses. If the revenue increases and this ratio decreases, it means that the management is skillfully optimizing the operating expenses. If it is the other way around, shareholders should wonder how well management is handling current affairs.

- ROE, % is a ratio reflecting the efficiency of a company's equity performance. If a company earned 5% of its equity, i.e. ROE = 5%, and the bank deposit rate = 7%, then shareholders have a reasonable question: why invest equity in business development, if it can be placed in a bank deposit and get more, without expending extra effort? In other words, ROE, % reflects the return on invested equity. If it is growing, it is definitely a positive factor for the company and the shareholders.

- Days payable. This financial ratio is an excellent indicator of the solvency of the company. We can say that it is the number of days it will take the company to pay all debts to suppliers from its revenue. If the number of days is relatively small, it means that the company has no delays in paying for supplies and therefore no money problems. I consider less than 30 days to be acceptable, but over 90 days is critical.

- Days sales outstanding. I already mentioned in my previous posts that when a company is having a bad sales situation, it may even sell its products on credit. Such debts accumulate in accounts receivable. Obviously, large accounts receivable are a risk for the company, because the debts may simply not be paid back. For ease of control over this indicator, they invented such a financial ratio as "Days sales outstanding". We can say that this is the number of days it will take the company to earn revenue equivalent to the accounts receivable. It's one thing if the receivables are 365 daily revenue and another if it's only 10 daily revenue. Like the previous ratio: less than 30 days is acceptable to me, but over 90 days is critical.

- Inventory to revenue ratio. This is the amount of inventory in relation to revenue. Since inventory includes not only raw materials but also unsold products, this ratio can indicate sales problems. The more inventory a company has in relation to revenue, the worse it is. A ratio below 0.25 is acceptable to me; a ratio above 0.5 indicates that there are problems with sales.

- Current ratio. This is the ratio of current assets to current liabilities. Remember, we said that current assets are easier and faster to sell than non-current, so they are also called quick assets. In the event of a crisis and lack of profit in the company, quick assets can be an excellent help to make payments on debts and settlements with suppliers. After all, they can be sold quickly enough to pay off these liabilities. To understand the size of this "safety cushion", the current ratio is calculated. The larger it is, the better. For me, a suitable current ratio is 2 or higher. But below 1 it does not suit me.

- Interest coverage. We already know that loans play an important role in a company's operations. However, I am convinced that this role should not be the main one. If a company spends all of its profits to pay interest on loans, it is working for the bank, not for the shareholders. To find out how tangible interest on loans is for the company, the "Interest coverage" ratio was invented. According to the income statement, interest on loans is paid out of operating income. So if we divide the operating income by this interest, we get this ratio. It shows us how many times more the company earns than it spends on debt service. To me, the acceptable coverage ratio should be above 6, and below 3 is weak.

- Debt to revenue ratio. This is a useful ratio that shows the overall picture of the company's debt situation. It can be interpreted the following way: it shows how much revenue should be earned in order to close all the debts. A debt to revenue ratio of less than 0.5 is positive. It means that half (or even less) of the annual revenue will be enough to close the debt. A debt to revenue ratio higher than 1 is considered a serious problem since the company does not even have enough annual revenue to pay off all of its debts.

So, the financial ratios greatly simplify the process of fundamental analysis, because they allow you to quickly draw conclusions about the financial condition of the company, without looking up and down at its statements. You just look at ratios of key indicators and draw conclusions.

In the next post, I will tell you about the king of all financial ratios - the Price to Diluted EPS ratio, or simply P/E. See you soon!
