To calculate a stock's real (intrinsic) value, use methods like Discounted Cash Flow (DCF) for future earnings, or simpler metrics like P/E Ratio (Price-to-Earnings), P/S Ratio (Price-to-Sales), and PEG Ratio, which compare price to earnings, sales, or growth, helping you find undervalued stocks by assessing profitability and potential beyond the current market price.
Intrinsic Value = EPS TTM x P/E Ratio
By multiplying the EPS TTM by the P/E ratio, you can estimate the intrinsic value of a stock.
