Valuation measures refer to methods used by investors, analysts and other market participants to determine the value or worth of a company's stock. These measures can provide insight into a company’s financial health, growth potential, profitability, and overall attractiveness as an investment. Some common valuation measures include price-to-earnings (P/E) ratio, price-to-book (P/B) ratio, and enterprise value-to-EBITDA (EV/EBIDTA). These ratios compare a company's stock price or market value to its earnings, book value, or cash flow to help determine if the stock is overvalued, undervalued, or fairly valued.
