Return on equity ratio is the company’s annual net income divided by shareholder’s equity.
Price to book ratio is the company’s market capitalization, or the stock price times number of outstanding shares, divided by the most recent quarter’s book value.
It’s important to understand what may be driving P/B ratios and to compare them across different companies in the same industry, as a high P/B ratio can mean positive investor sentiment, but a low P/B ratio can mean that the company has significant assets to back up the stock price.
If a company has $50,000,000 in debt and $100,000,000 in shareholder’s equity, its debt-to-equity ratio is 0.5.
