About the metric
What return on equity (ROE) means
Return on equity (ROE) measures how much net income a company generates relative to shareholders’ equity. It can help evaluate how efficiently equity capital is used, but unusually high or negative values may reflect leverage, losses, or a small equity base.
Calculation and source
How return on equity is calculated
TickerStat calculates ROE as SEC-reported net income divided by average stockholders’ equity at the beginning and end of the fiscal period. Periods with missing or non-positive average equity are omitted. Quarterly ROE uses quarterly net income and is not annualized. Fiscal periods can differ from calendar years, so exact period-end dates are included.
