Before he joined Bloomberg, Matt got his start at www.dealbreaker.com. During my stint on wall st (2006~2015), DealBreaker was THE industry rag of choice. Daily news roundups, annual bonus/compensation gossip, rumors of pending layoffs or reorgs, all in one place.
There is so much boring shit you have to read on a daily basis when working in capital markets. Breaking geopolitical news, WSJ / Financial Times / Economist / Bloomberg articles, endless internally published market commentary, all of it often written by someone who takes themselves too seriously. Matt Levine was a breath of fresh air, someone who was both technical AND irreverent.
Nobody trades off of Matt's articles. Nothing he writes about is secret. His best stuff takes the form of "this weird thing happened" or "XYZ made a dumb mistake." Matt is funny, and funny is VERY underrated in financial commentary.
