Warren Buffett

so how do Warren Buffett and Charlie Munger (Vice Chairman of Berkshire Hathaway) see quantitative financial analysis?

According to Buffett: “If you need to use a computer or a calculator to make the calculation, you shouldn’t buy it,”

And according to Munger: "“Some of the worst business decisions I’ve ever seen are those with future projections and discounts back. It seems like the higher mathematics with more false precision should help you, but it doesn’t. They teach that in business schools because, well, they’ve got to do something.”
