CoStar Group  (MIL:1CSGP) 3-Year RORE % Explanation

Return on Retained Earnings (RORE) is important to investors because it reveals a company's efficiency and growth potential. A higher RORE indicates a higher return. A high RORE indicates that the company should reinvest profits into the business. A lower RORE suggests that the company should distribute profits to shareholders by paying out dividends, since those dollars aren't generating much additional growth for the company.

There are a several different ways to arrive at the Return on Retained Earnings. The simplest way to calculate it is by using published information on Earnings per Share (EPS) and Dividend per Share (DPS) over a selected period. Here, 3-year period is chosen.

Be Aware

Please keep in mind that the RORE is relative to the nature of the business and its competitors. If another company in the same sector is producing a lower return on retained earnings, it doesn’t necessarily mean it’s a bad investment. It may just suggest the company is older and no longer in a high growth stage. At such a stage in the business cycle, it would be expected to see a lower RORE and higher dividend payout.
