Return on invested capital is one of the most important investment tools according to Charlie Munger. In this video I show how to calculate return on investment capital (ROIC), show two examples and how those affected stock market returns and individual stock returns. ROIC is more than just another financial metric, it is a financial performance indicator that really helps in the value creation of a company and for long term investment returns. ROIC is what made Buffett and Munger billionaires. I explain how you can become a billionaire or just millionaire too by using the roid.
