The importance of P/E and P/S ratios

While the strategies we deploy can apply to just about every type of stock out there, stock valuation is a crucial aspect of investment decision-making. Investors often rely on financial metrics to determine the worth of a stock and whether it's undervalued, overvalued, or priced just right. Two of the most commonly used metrics for stock valuation are the price-to-earnings (P/E) ratio and the price-to-sales (P/S) ratio. In this blog post, we will explore the significance of both ratios and how they can help investors make informed decisions.


Understanding the P/E Ratio


The P/E ratio is a measure of a company's current share price relative to its earnings per share (EPS). It is calculated by dividing the current stock price by the EPS. A lower P/E ratio typically indicates that a stock is undervalued, while a higher P/E ratio suggests that a stock may be overvalued.


The P/E ratio is particularly useful for comparing companies within the same industry, as it accounts for differences in their size and growth potential. However, it's worth noting that the P/E ratio should be used in conjunction with other financial metrics, as it does not account for a company's debt or cash reserves.

The Importance of the P/S Ratio


The P/S ratio is another essential metric for stock valuation, which measures a company's market capitalization (total value of its outstanding shares) against its total sales or revenue over a given period. It is calculated by dividing the company's market cap by its total sales.


A lower P/S ratio indicates that a stock may be undervalued, while a higher P/S ratio suggests that a stock could be overvalued. This ratio is particularly useful for evaluating companies with little or no earnings, such as startups or companies in the early stages of growth. It can also provide insights into a company's sales performance relative to its market value.


Using P/E and P/S Ratios Together


While both the P/E and P/S ratios are valuable tools for stock valuation, using them in tandem can offer a more comprehensive understanding of a company's financial health and potential for growth.


For example, a company with a low P/E ratio and a high P/S ratio may be experiencing temporary difficulties in generating profits, but its strong sales performance could indicate future earnings growth. Conversely, a company with a high P/E ratio and a low P/S ratio may have strong current earnings but limited sales growth, which could impact its long-term profitability.


For both of these metrics it's important to measure these metrics in comparison to a stock's competitors or overall industry to gauge whether it is relatively overvalued or undervalued based on the respective metric.


When we sell puts we want to ensure that the companies we are selling puts on are good value stocks that we'd be comfortable with holding. While they don't tell the entire story, the P/S and P/E ratios are two great fundamental metrics to use as a starting point in evaluating a potential position.
