An Ivy League business school where Mauboussin teaches security analysis.
Columbia Business School appears only as the setting where Michael Mauboussin has taught security analysis for 32 years, a course dating to Ben Graham in 1927. Sources give no growth or product data. The takeaway for builders is about writing: use it to expose gaps in what you think you understand, and learn an idea's history before writing about it.
From Michael Mauboussin, Columbia Business School class
Mauboussin's Columbia security analysis class teaches concepts before formulas. Michael Mauboussin, in his 32nd year teaching security analysis at Columbia Business School, opens the class with a Latin line credited to Gauss: 'Not notations, but notions.' The aim is for students to learn the underlying concepts, not just the formulas.
The class traces back to Ben Graham, who began teaching it in 1927. Graham also wrote plays and translated Greek and Latin classics, and writing was a big part of how he got his message out. Mauboussin applies the same idea to writing, which he treats as the test of whether he truly understands something.
Teaching an idea's history surfaces forgotten figures students never learned. Mauboussin's Columbia students know Ben Graham but have never heard of John Burr Williams. He traces where an idea came from, why we are where we are, and where it may go, which turns up figures like Williams and gives the material depth.
"I find it super helpful to understand the history."
