COOPER CREEK PARTNERS MANAGEMENT LLC — 13F Portfolio

COOPER CREEK PARTNERS MANAGEMENT LLC is a U.S.-based hedge fund manager focused on fundamental, research-driven long/short equity investing. Structured as a private investment adviser serving institutional investors and sophisticated limited partners, the firm manages hedge fund and related vehicles that concentrate primarily in North American equities, with a notable emphasis on smaller and mid-sized issuers where active investors can exert influence and exploit inefficiencies. The adviser is registered with the U.S. Securities and Exchange Commission and qualifies as an institutional investment manager under Section 13(f). COOPER CREEK PARTNERS MANAGEMENT LLC files quarterly Form 13F with the SEC under CIK 0001512162. These filings disclose the firm’s long U.S.-listed equity and certain equity-linked positions, including common stocks, ADRs, and, where applicable, reportable ETFs or other 13(f) securities held across its managed accounts. Only the long side of the U.S.-listed equity book appears in Form 13F. Short positions, derivatives, non-U.S. listings, and many credit or hybrid instruments that may be integral to the strategy are outside the 13F regime. Even so, the filings provide a regulator-defined trail of COOPER CREEK’s disclosed long holdings and can be organized into a continuous 13F History, forming the empirical backbone for allocator-grade analysis of the firm’s public-equity implementation.

COOPER CREEK PARTNERS MANAGEMENT LLC pursues a fundamental long/short equity strategy with a distinctive bias toward value, event-driven, and occasionally activist situations in the small- and mid-cap universe. The core premise is that less efficiently followed companies, particularly outside the large-cap benchmark complex, frequently exhibit mispricings that can be unlocked through deep research, constructive engagement, and careful structuring of both long and short books. Typical characteristics of the strategy include: - Fundamental, bottom-up research: The team focuses on business models, cash-flow dynamics, balance-sheet strength, governance, and industry structure. This work often targets companies undergoing change—corporate restructurings, portfolio shifts, capital allocation inflection points, or management transitions. - Value and catalyst orientation: Long positions are generally built where the manager sees a discount to intrinsic value supported by identifiable catalysts (corporate actions, strategic reviews, asset sales, operational improvement, or potential M&A). On the short side, the firm may target structurally challenged businesses, aggressive accounting, or unsustainable capital structures. - Small- and mid-cap focus: The opportunity set skews toward smaller companies where active investors can engage with management and boards and where market attention and sell-side coverage are often limited. This can create a fertile environment for differentiated views and idiosyncratic alpha. - Opportunistic activism and engagement: While not exclusively an activist, COOPER CREEK has the tools and experience to be a vocal shareholder when necessary, including public letters and shareholder proposals. More often, engagement is private and focused on governance, capital allocation, and strategic clarity. The portfolio is concentrated, with capital deployed into a limited number of high-conviction longs and a complementary set of shorts. Gross and net exposure are actively managed based on the breadth of opportunity, perceived market risk, and the balance between long and short alpha. In the Form 13F dataset, this philosophy manifests as a focused roster of U.S.-listed longs, frequently in smaller-cap consumer, industrial, business services, and selected financial or technology names. Quarter-to-quarter changes in the 13F Portfolio Composition can reveal the initiation and build-out of new theses, the exit of realized ideas, and the degree of persistence in core positions. Using a Portfolio Simulator and Backtesting Service, these disclosed holdings can be mapped into a normalized long-only U.S. equity sleeve to produce a synthetic Historical Track Record for the 13F-visible portion of the strategy. This reconstruction does not capture the short book or non-U.S. activity, but it offers a tractable way to study how the firm’s long equity selections have contributed to its overall capital trajectory through different market environments.

COOPER CREEK PARTNERS MANAGEMENT LLC represents a classic fundamental hedge fund model focused on extracting value from mispriced small- and mid-cap equities through concentrated long/short portfolios and, where necessary, active engagement. Its Form 13F filings under CIK 0001512162 provide one of the few systematic windows into this activity, revealing a compact list of U.S.-listed longs that embody the manager’s highest-conviction ideas at each quarter-end. Organizing these disclosures into a time series of 13F Portfolio Composition allows allocators and researchers to observe structural features of the strategy: the degree of issuer and sector concentration, the persistence of core holdings, and the cadence with which new names enter and exit the book. Feeding this holdings history into a Portfolio Simulator enables construction of a synthetic Historical Track Record for the long U.S. equity sleeve, normalized to a chosen starting notional and providing a basis for historical replication of the visible capital trajectory. On top of that reconstructed series, downside diagnostics such as Max Drawdown Depth and efficiency measures like the Sharpe Ratio—derived via Performance Backtests Online—offer a concise, quantitative frame for how COOPER CREEK’s disclosed long portfolio has navigated prior cycles of small-cap volatility, value/growth rotations, and market-wide stress. These analytics cannot reveal the full dynamics of the hedge fund, given the absence of short, derivative, and non-U.S. positions in 13F data, but they provide a disciplined, empirically grounded lens on the manager’s public long-equity expression. The key open question for forward-looking allocators is how this concentrated, value- and catalyst-driven style—implemented predominantly in the less-liquid small- and mid-cap universe—will respond if the prevailing regime shifts toward persistently higher real rates, structurally different factor leadership, or extended periods of subdued corporate activity that may delay or diminish the catalysts on which many of COOPER CREEK’s investment theses rely.

The risk profile of COOPER CREEK PARTNERS MANAGEMENT LLC reflects its identity as a concentrated, fundamental long/short equity manager operating largely in the less-liquid small- and mid-cap segments. At the total-portfolio level, risk is governed by position sizing, gross and net exposure management, diversification across themes, and active oversight of the short book. Within the narrower lens of Form 13F, only the long U.S.-listed holdings are visible, but several key dimensions of risk can still be inferred. 1. Equity market and style risk
The long book is structurally exposed to equity market moves, particularly in the segments where the firm concentrates—smaller caps and value/catalyst-driven names. Broad risk-off episodes, factor rotations away from value or smaller capitalization, and spikes in volatility can all drive marked drawdowns in the disclosed holdings, even if the overall hedge fund mitigates these via shorts and other hedges. 2. Concentration and idiosyncratic risk
COOPER CREEK runs a high-conviction portfolio. Top positions often command significant weight within the disclosed book, and many holdings are linked to specific corporate events or catalysts. This heightens idiosyncratic risk: earnings surprises, deal breaks, regulatory actions, or governance disputes at individual companies can have outsized impacts on the capital path of the 13F sleeve. 3. Liquidity and capacity risk
A focus on small- and mid-cap names inherently involves thinner liquidity and wider bid–ask spreads than large-cap benchmarks, particularly in stressed markets. While position sizes are generally managed with liquidity in mind, market dislocations can still increase the cost of repositioning or exiting trades. 4. Short-book and basis risk (not visible in 13F)
At the strategy level, risk is also shaped by the interaction between the long and short books—basis trades, pair trades, sector and factor hedges, and gross exposure adjustments. None of these appear in 13F data, meaning the risk of the disclosed long sleeve may overstate or misstate the risk of the net portfolio actually experienced by investors. By reconstructing the reported holdings into a time-series portfolio, analysts can estimate realized downside and variability metrics for the visible U.S. long book. In particular, examining Max Drawdown Depth during major equity sell-offs and periods of acute small-cap or value stress provides a clear indication of the worst peak-to-trough declines that the 13F sleeve has experienced. A rolling analysis of the reconstructed capital path yields a time-varying Volatility Profile, highlighting whether the long book has behaved as a high-beta satellite relative to broad equities, or whether security selection has moderated volatility compared with more speculative small-cap cohorts. Overlaying a portfolio-level Sharpe Ratio on this synthetic history summarizes the risk-adjusted outcomes of the disclosed longs—how the combination of concentrated value and event-driven ideas has translated into capital growth relative to the volatility borne, acknowledging that this view excludes shorts, leverage, and non-U.S. exposures.
