Keep in mind the refrain of most professors before explaining any quant models - "All models are wrong but some are useful" - DCF is one such model but once you start believing all your manufactured and questionable inputs to the model, the output reflects your bias.

"Someone acquiring an entire business is likely to think on similar lines." This is the key IMHO. What they teach you in B-scools and even CFA is for investment banks, buyers and sellers of whole companies or strategic stakes. Metrics for investors, have to be different. These are not taught and so every successful investors develops is own. Excellent piece as always

The most important metric being Return on Capital as it answers most of the important questions regarding the quality of a business saves a lot of time for investors to filer out companies.

I think the 2nd quote is from Yogi Bera. Not from Albert Einstein

"A business with 30% ROE growing 10% a year is left with two-thirds of profit as surplus cash. A 15% ROE business is only left with one third." can you explain this, sry couldn't understand it.

I think this is what is means, ROE * Reinvestment Rate = Expected Growth

30% * X = 10% for business1

15% * Y = 10% for business2

The author is expecting both the businesses to grow at 10% and trying to calculate how much re-investment is needed.

X = 1/3

Y = 2/3

After spending 1/3rd of money for growth, business1 is left with 2/3rds of money as profit.

After spending 2/3rds of money for growth, business2 is left with 1/3rd of money as profit.

Loved it Sridhar. Going just by one parameter is suicidal, a combination of multiple parameters like capital allocation, competitive nature of business, integrity of management, risk, DCF etc., and validating of our observations on a regular basis increases our probability of success.
