P/B Ratio: Values below 1.0 suggest the stock trades below its net asset value, which could indicate undervaluation or fundamental problems. Technology companies often trade at higher P/B ratios.
P/S Ratio: Useful for unprofitable companies or comparing revenue efficiency. Lower is generally better, but high-margin businesses can justify higher P/S ratios.
EV/EBITDA: Accounts for debt and excludes non-cash expenses, making it ideal for comparing companies with different capital structures. Values under 10x often indicate good value.
