Otter Creek Long/Short Opportunity Fund - Investor Class (OTCRX) is an open-end mutual fund that employs a long/short equity investment strategy to pursue long-term capital appreciation while managing risk through positions in undervalued long securities and overvalued short securities, primarily U.S.-listed equities; it maintains net long exposure typically ranging from -35% to +80%, with gross long and short equity exposures around 95% and -49% respectively as of recent periods, supplemented by put options on shorts when appropriate, and implements rigorous position-level and portfolio-level risk management including margin of safety assessments, liquidity monitoring, limited leverage historically, and Value at Risk analysis relative to the S&P 500. The fund, domiciled in the United States and available to U.S. investors with a minimum initial investment of $2,500, operates within the Equity Market Neutral category and features a net expense ratio of approximately 2.31%, with a contractual fee waiver capping expenses until at least February 28, 2025. Managed by Otter Creek Advisors, LLC—headquartered in Palm Beach Gardens, Florida, a successor entity formed in 2014 to the firm's origins in 1991 under Otter Creek Management Inc.—the fund launched on December 30, 2013, under lead portfolio managers Tyler C. Walling (since inception) and Cory J. Reed, CFA (since 2022), who oversee approximately $150 million in assets across Investor (OTCRX) and Institutional (OTTRX) share classes as of recent data. In a notable strategic expansion within the last two years, Otter Creek Advisors launched the Otter Creek Focus Strategy ETF (OCFS) in May 2024, converting a separately managed account strategy initiated in 2020 into an actively managed ETF targeting 20-25 high-quality small- to mid-cap U.S. equities with superior profitability, growth, and free cash flow profiles relative to the Russell Midcap Index, managed by the same team and holding over $5 million in assets with a 0.85% expense ratio. This ETF launch represents the firm's entry into the ETF market, building on its long/short heritage while diversifying product offerings amid dynamic portfolio reallocations in response to 2024 market appreciation and 2025 volatility.
