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, publishing content for Forbes, Fortune, CFA Institute, Kiplinger, MarketWatch and several other financial media publications while also being quoted by TheStreet and CNBC. Originally, Blotnick’s focus was on stock picks and market commentary, but over the years he developed a niche that resonated with readers at the crossroads of behavioral finance and human nature, exploring the psychological biases, thinking errors and self-sabotaging tendencies which 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.
