While the P/S ratio is an important valuation metric, it should be used in conjunction with other metrics like P/E, P/B, and EV/EBITDA to gain a comprehensive understanding of a company's financial health. Each metric provides a different perspective on a company's valuation and performance. For example, the P/E ratio focuses on earnings, the P/B ratio on book value, and EV/EBITDA on earnings before interest, taxes, depreciation, and amortization.
