Return on equity (ROE)
One of the most important ratios for investors to understand is return on equity, or the return a company generates on its shareholders' capital. In one sense, it's a measure of how good a company is at turning its shareholders' money into more money.
P/E ratio, or price-to-earnings ratio, is a quick way to see if a stock is undervalued or overvalued. And so generally speaking, the lower the P/E ratio is, the better it is for both the business and potential investors.
Among the various methods available, three of the most widely used valuation techniques are the Discounted Cash Flow (DCF) analysis, the Price-to-Earnings (P/E) ratio, and the Price-to-Book (P/B) ratio. These methods provide a comprehensive approach to assessing a stock's value and are integral to successful investing.
If the price-to-sales ratio is 1, investors are paying $1 for every $1 of revenues generated by the company. A stock with a price-to-sales below 1 is a good bargain as investors need to pay less than a dollar for a dollar's worth.
Ideally, it's best to keep this ratio between 0.167 and 0.25.
Ideally, a P/B value under 1.0 is considered good as it indicates that the stock is potentially undervalued. However, value investors often consider stocks with a P/B value under 3.0. The P/B ratio helps to identify low-priced stocks with high growth prospects.
What are good ratios for a company? Generally, the most often used valuation ratios are P/E, P/CF, P/S, EV/ EBITDA, and P/B. A “good” ratio from an investor's standpoint is usually one that is lower as it generally implies it is cheaper.
The most common way to value a stock is to compute the company's price-to-earnings (P/E) ratio. The P/E ratio equals the company's stock price divided by its most recently reported earnings per share (EPS). A low P/E ratio implies that an investor buying the stock is receiving an attractive amount of value.
Price-to-earnings ratio (P/E): Calculated by dividing the current price of a stock by its EPS, the P/E ratio is a commonly quoted measure of stock value. In a nutshell, P/E tells you how much investors are paying for a dollar of a company's earnings.
Typically, the average P/E ratio is around 20 to 25. Anything below that would be considered a good price-to-earnings ratio, whereas anything above that would be a worse P/E ratio.
ROE is calculated by dividing net profit by net worth. If the company's ROE turns out to be low, it indicates that the company did not use the capital efficiently invested by the shareholders. Generally, if a company has ROE above 20%, it is considered a good investment.
A beta coefficient of less than 1 means that a stock tends to be less volatile than the overall market. Utility and real estate stocks are two examples of industries that typically have low betas. A beta coefficient of more than 1 means that a stock tends to be more volatile than the overall market.
Debt to Equity Ratio
This key ratio is comparing the debt to the equity in the company. Warren Buffett prefers a company with a debt to equity ratio that is below . 5. In other words, for every $10 in equity the company should only have $5 in debt.
What is a good inventory turnover ratio? For most industries, a good inventory turnover ratio is between 5 and 10, which indicates that you sell and restock your inventory every 1-2 months. This ratio strikes a good balance between having enough inventory on hand and not having to reorder too frequently.
Metrics like earnings growth, price-to-earnings (P/E) ratio, and profit margin can potentially help isolate possible danger signs for a stock. Traders often compare a stock to its sector and see how it's doing compared to other stocks. Case in point: the P/E ratio.
The most common way of valuing a stock is by calculating the price-to-earnings ratio. The P/E ratio is a valuation of a company's stock price against the most recently reported earnings per share (EPS). Investors use the P/E ratio as a yardstick to measure a company's stock value.
Determining fair value
The Peter Lynch fair value calculation assumes that when a stock is fairly valued, the trailing P/E ratio of the stock (Price/EPS) will equal its long-term EPS growth rate: Fair Value = EPS * EPS Growth Rate.
An Appraisal Ratio greater than 1.0 indicates that the Appraisal Per Share is higher than the stock price, and that the stock is undervalued. An Appraisal Ratio less than 1.0 indicates the stock is overvalued.
Price-earnings ratio (P/E)
A high P/E ratio could mean the stocks are overvalued. Therefore, it could be useful to compare competitor companies' P/E ratios to find out if the stocks you're looking to trade are overvalued. P/E ratio is calculated by dividing the market value per share by the earnings per share (EPS).
Buffett's Strategy
Warren Buffett, the greatest value investor of this century, now tends to buy stocks with a P/B ratio of around 1.3.
A bad price to book ratio a company can have is anything above 1. If a company has a P/B ratio of above 1, the company's share price is considered overvalued and not a good investment.
What should the book to market factor be? Generally, the results of your book to market ratio should be around 1. Less than 1 implies that a company can be bought for less than the value of its assets. A higher figure of around 3 would suggest that investing in a company will be expensive.
