Quest Diagnostics  (FRA:QDI) Return-on-Tangible-Equity Explanation

Return-on-Tangible-Equity measures the rate of return on the ownership interest (shareholder's tangible equity) of the common stock owners. It measures a firm's efficiency at generating profits from every unit of shareholders' tangible equity (shareholders equity minus intangibles). Return-on-Tangible-Equity shows how well a company uses investment funds to generate earnings growth. Return-on-Tangible-Equitys between 15% and 20% are considered desirable.


Be Aware
