As for the ratios you’ll be calculating from these sources, there are dozens that investors and analysts use, but we've chosen 30 important measurements that are the most relevant to the investing process and organized them into six main categories as per the following list. The ratios are presented in a simplified manner to make them easier to understand. These ratios come in a number varieties – some to analyze liquidity some profitability, and some use of debt, for example – but by the end you will understand the basic premise and reasons for fundamental analysis.
Total liabilities divided by total assets or the debt/asset ratio shows the proportion of a company's assets which are financed through debt. If the ratio is less than , most of the company's assets are financed through equity. If the ratio is greater than , most of the company's assets are financed through debt. Companies with high debt/asset ratios are said to be highly leveraged. The higher the ratio, the greater risk will be associated with the firm's operation. In addition, high debt to assets ratio may indicate low borrowing capacity of a firm, which in turn will lower the firm's financial flexibility. Like all financial ratios, a company's debt ratio should be compared with their industry average or other competing firms.
