Gregory Blotnick

Gregory Blotnick is an investor, entrepreneur, and author based in West Palm Beach, Florida.

Blotnick was most recently the founder and portfolio manager of Brattle Street Capital LLC, a long/short equity hedge fund in New York City. Brattle Street’s focus was on small and mid-cap opportunities within the Consumer & Retail sector, with a specific objective of seeking out idiosyncratic investments that were too small or illiquid for larger multi-manager hedge funds to take advantage of given myriad portfolio constraints and mandate restrictions. Brattle Street was formed and designed to capitalize on these same inefficiencies that result from those constraints.

Previously, Blotnick worked at the hedge funds Citadel LLC and Schonfeld Strategic Advisors, where he covered the Consumer & Retail sector. Since 2009, Blotnick has continued to develop expertise across multiple sub-sectors, analyzing hardlines, softlines, consumer durables and consumer technology stocks, to which he was regularly assigned coverage at several hedge funds throughout the New York area. He continues to write and publish research on investing and on the Consumer sector.

Beyond his analytical work, Blotnick is a frequent financial writer and commentator. His insights and analysis have been featured across numerous respected financial publications, including Fortune, Kiplinger, Forbes, SSRN, CFA Institute, NASDAQ, NewsMax, Investing.com, Harvest, and many others.

For over a decade, Blotnick has continued to write and contribute regularly for the general investing public, demonstrating his ability to clearly communicate and break down complex financial concepts to broader audiences without losing analytical rigor. His primary area of focus is on behavioral finance and investor psychology, tracking the cognitive biases that can cause individuals into poor decision-making and negatively impact their performance. In 2025, Blotnick published his first book, Blind Spots: A Riches to Rags Story.

Blotnick holds an MBA from Columbia Business School and a Bachelor of Science in Finance from Lehigh University. He currently resides in Palm Beach County.
