Key Points

The equity multiplier measures how much a company relies on debt versus shareholders' equity.
DuPont analysis breaks down ROE using the equity multiplier to indicate risk and earning power.
Watching the equity multiplier helps assess if increased ROE is due to debt or operational efficiency.

The equity multiplier is a useful tool for investors to monitor risk and understand how a company generates returns for investors. It's helpful by itself and as part of a DuPont analysis, which is a financial tool that breaks out how a company generates a return on equity (ROE).

A rising equity multiplier is obviously a concern. Still, the company has also significantly improved its profitability (income/sales) and how much sales it generates from its assets (sales/assets) over the same period. In other words, Illinois Tool Works is excellently sweating its assets, even if those assets were supported by taking on more debt.

In this case, the rising equity multiplier is not such a concern.

However, suppose the equity multiplier had risen while sales/assets and income/sales were static or declining. In that case, it's possible ROE could have increased because the company was taking on debt.

This is not a problem while the interest rate environment is benign, but it's a risky strategy when conditions change. As such, keeping an eye on the equity multiplier in the context of how a company generates earnings is a good idea. It tells you a lot aout the direction of a company.
