Protagenic Therapeutics  (OTCPK:PTIX) 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

Net Income is used.

Because a company can increase its Return-on-Tangible-Equity by having more financial leverage, it is important to watch the leverage ratio when investing in high Return-on-Tangible-Equity companies. Like Return-on-Tangible-Asset, Return-on-Tangible-Equity is calculated with only 12 months data. Fluctuations in company's earnings or business cycles can affect the ratio drastically. It is important to look at the ratio from a long term perspective.

Asset light businesses require very few assets to generate very high earnings. Their Return-on-Tangible-Equitys can be extremely high.
