Debt Equity Ratio
A measure of a company’s financial leverage calculated by dividing long-term debt by stockholder equity. It indicates what proportion of equity and debt the company is using to finance its assets. Generally, a lower D/E is considered more favorable.
Earnings Per Share Ratio
The portion of a company’s profit allocated to each outstanding share of common stock. It serves as an indicator of a company’s profitability. Generally, a higher EPS is considered more favorable.
