Return on Equity - it is the long-term return on capital that excites

The way analysts usually measure return on capital for publicly traded companies is return on equity, or ROE.  

ROE =  Net earnings / Shareholders' equity

Shareholders' equity, or equity capital = Total assets - Total liabilities

Shareholders' equity is the part of the company owned by stockholders - the capital they have invested in the company.

A company X earned an incredible 63% on its equity capital in 1999.   In other words, for every $1 of shareholder money invested in the firm, this company X generated an annual profit of $0.63.

Be careful, though.  It is easier to post a large ROE in a single year than it is to maintain that large ROE over a longer period.

Company Y, for example, earned 58% on its equity in 1999, but if you average the company's ROEs over the five-year period from 1995 to 1999, the figure drops to a much less impressive 19%.

It is that long-term return on capital that we're interested in.
