Gregory J. Blotnick is an entrepreneur and writer based in West Palm Beach, Florida. He brings over a decade of experience in long/short portfolio management and fundamental equity research.
Background
Gregory Blotnick was born in 1986 in New York City, the son of Srully Blotnick, an author and PhD in cell biology from Harvard Medical School. Blotnick grew up in Cambridge, Massachusetts, and graduated from Buckingham Browne & Nichols School in 2005.
Investing
After graduating from Lehigh University in 2009, Blotnick was hired as an analyst at hedge fund Doubloon Capital in Connecticut. He later joined Exis Capital in New York, earning his CFA charter in 2012 before pursuing an MBA at Columbia Business School.
In 2017, Citadel LLC hired Blotnick as a Consumer sector specialist, where he was part of a five-person team managing over $1 billion in gross market value. In 2019 Blotnick founded Brattle Street Capital, a New York-based hedge fund focused on opportunities within the Consumer sector, particularly amidst small and mid-cap equities.
Writing
Blotnick began writing in 2012 under the pseudonym Brattle Street Capital, named after the street he grew up in Cambridge. His Twitter account (@brattlestcap) was recognized as a “must-follow” and named one of the top influential accounts by Business Insider and Forbes. Blotnick went on to publish content under his real name for Forbes, Fortune, CFA Institute, Kiplinger, NewsMax, MarketWatch, Financial Sense, Seeking Alpha, and many other financial media outlets.
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, Blotnick published his first book, Blind Spots: A Riches to Rags Story.
