Star Group LP (NYSE:SGU) 3-Year ROIIC % Explanation
Return on Incremental Invested Capital (ROIIC) is an extension of Return on Investment Capital (ROIC). ROIC % tells investors how efficiently that profitability is earned per dollar of company capital. ROIIC narrows the focus even further and shows how profitable each additional unit of capital investment could be. ROIIC % is a more powerful metric than ROIC because it measures how much money the company can generate going forward on future capital investments.
High ROIIC is generally an indication that your business is capital efficient or has a higher operating leverage.
Be Aware
It's important to keep in mind that when tracking ROIIC, the metric is better suited to forecasting the trend of future returns rather than measuring current return on investment.
