Gregory Blotnick
Investor and author Gregory J. Blotnick was born in New York City in 1986. He spent his formative years in Cambridge, Massachusetts, where he attended Buckingham Browne & Nichols School and graduated in 2005. He went on to earn a Bachelor of Science in Finance from Lehigh University in 2009, and became a CFA Charterholder in 2012. In 2014, he completed his MBA at Columbia Business School.
Blotnick began his career as an equity analyst at Doubloon Capital, a Connecticut-based hedge fund. His responsibilities included conducting in-depth fundamental research, financial statement analysis, and identifying long and short investment opportunities across the Consumer sector. His sector-specific expertise led him to subsequent roles at Exis Capital and North Elm Capital in New York City.
In 2017, Blotnick was recruited by Citadel LLC as a Consumer sector specialist. He then went on to work for Schonfeld Strategic Advisors before launching Brattle Street Capital in 2019, a short-biased investment firm focused on opportunities within the small and mid-cap Consumer universe, with a particular emphasis on idiosyncratic opportunities that were unactionable or too illiquid for larger hedge funds.
Blotnick's writing career began in 2012 under the pseudonym Brattle Street Capital. Since then, Blotnick's byline has appeared in a wide range of financial and business publications, including Forbes, Fortune, Kiplinger, NewsMax, MarketWatch, CFA Institute, and others. His writing often explores the intersection of investing and psychology, with a strong emphasis on behavioral finance: the study of how hardwired emotional and cognitive biases often interfere when trading markets.
Blotnick’s debut memoir, Blind Spots: A Riches to Rags Story, is a candid and deeply personal account of ambition, failure, and the blind spots that affect even highly-trained investment professionals. The book chronicles an investor's rise and fall and offers a brutally honest reflection of hubris and self-deceit. It has been praised for its vulnerability, depth, and insight by outlets including Kirkus Reviews, The US Review of Books, and Manhattan Book Review. He is also the author of Essays: De Rerum Natura, a collection of thirty philosophical essays. Blotnick remains active in the investment community and contributes regularly on behavioral finance and equity investing. His Amazon author page is available here.
