21. Leverage is usually defined by the Debt-to-Equity Ratio, which doesn't involve Market Cap

What Is the Debt-To-Equity Ratio – D/E?

The debt-to-equity (D/E) ratio is calculated by dividing a company’s total liabilities by its shareholder equity. These numbers are available on the balance sheet of a company’s financial statements.

The ratio is used to evaluate a company's financial leverage. The D/E ratio is an important metric used in corporate finance. It is a measure of the degree to which a company is financing its operations through debt versus wholly-owned funds. More specifically, it reflects the ability of shareholder equity to cover all outstanding debts in the event of a business downturn.

Market capitalization represents funds theoretically available to the shareholders, not to the corporation. It is important only in that a high stock price allows the company to raise new equity without dilution.
