Bloomberg View columnist Barry Ritholtz interviews Matthew Rothman, the head of global quantitative equity research at Credit Suisse and a senior lecturer in finance at the MIT Sloan School of Management. He was hired a few years before the financial crisis hit to be the global head of quantitative research at Lehman Brothers (and then moved to Barclays Capital, following the Lehman bankruptcy). In the midst of the quant crash in 2007, he published “Turbulent Times in Quant Land,” which became the most highly distributed research note in Lehman’s history. He is a huge Bruce Springsteen fan, and as an analyst often weaved song lyrics into his research notes.
