About

Gregory J. Blotnick is a fund manager and author. In 2019, Blotnick founded Brattle Street Capital, a long/short equity fund based in New York. Previously, Blotnick served a research analyst at some of the industry’s largest hedge funds, including Citadel and Schonfeld, where he specialized in the Consumer sector. He holds an MBA from Columbia Business School and a B.S. in Finance from Lehigh University.

Blotnick began writing in 2012 under the Twitter pseudonym Brattle St. Capital, named after the street he grew up on. He then started publishing long-form content under his real name and went on to write for Forbes, Fortune, the CFA Institute, Kiplinger, MarketWatch and several other financial media publications while also being quoted by TheStreet and CNBC. Originally, Blotnick’s content was limited to stock picks and market commentary, but over the years he developed a niche that resonated with readers at the crossroads of behavioral finance, the psychological biases inherent to human nature and the myriad thinking errors that cause us to become our own worst enemies, not just in investing but in life. In 2025, he published his first book: Blind Spots: A Riches to Rags Story.

Blotnick currently resides in West Palm Beach, Florida. He can be found on X at @gregoryblotnick.
