It defines five key ratios: return on equity (ROE), earnings per share (EPS), price-earnings ratio (P/E), return on common equity (ROCE), and market to book ratio. For each ratio, it provides the calculation and explains how the ratio is used and what higher or lower values may indicate about the company's financials and stock price.
