STEELHEAD PARTNERS LLC

Steelhead Partners LLC is a Seattle-based hedge fund specializing in convertible securities and event-driven investment strategies. Founded by Michael Johnston, the firm has established itself as a recognized practitioner in the convertible arbitrage space, managing capital for institutional investors and qualified high-net-worth clients. Steelhead Partners files quarterly 13F disclosures with the SEC under CIK #1133521, providing transparency into its U.S. equity and equity-related holdings spanning over two decades of operations. Headquartered in Seattle, Washington, Steelhead Partners operates from the Pacific Northwest's growing financial hub, which has evolved beyond its technology and aerospace roots to host sophisticated alternative investment managers. Under the leadership of Founder and Chief Investment Officer Michael Johnston, with James Bradshaw serving as President and Chief Operating Officer, the firm has cultivated deep expertise in convertible securities analysis and hedging strategies. The firm's name evokes the Pacific Northwest's iconic steelhead trout—known for navigating both fresh and saltwater environments—an apt metaphor for an investment approach that moves fluidly between equity and fixed income characteristics inherent in convertible securities. This specialized focus has enabled the firm to build institutional-quality infrastructure and analytical capabilities in a complex but potentially rewarding market niche.

Steelhead Partners employs a convertible arbitrage and event-driven investment strategy that seeks to extract value from pricing inefficiencies in convertible securities and related instruments. The firm's approach combines fundamental credit analysis with sophisticated hedging techniques to isolate specific return drivers while managing market exposure. Convertible arbitrage strategies typically involve purchasing convertible bonds or preferred securities while simultaneously shorting the underlying common stock, creating positions designed to profit from the convertible security's embedded optionality while neutralizing directional equity exposure. Analysis of the firm's 13F Portfolio Composition reflects the equity side of these hedged positions, with disclosed holdings representing delta hedges and directional equity exposures across various sectors. The investment methodology requires deep expertise in convertible security valuation, including assessment of credit quality, conversion features, call provisions, and embedded optionality. Sector Allocation History in disclosed 13F holdings often reflects the sectors where convertible issuance is most active, with technology and consumer companies historically prominent convertible issuers given their growth profiles and financing needs. Top 10 Holdings Concentration in the equity portfolio must be understood within the context of the broader convertible strategy. Individual equity positions may represent hedges against convertible holdings rather than directional bets, creating portfolio dynamics that differ fundamentally from traditional long-only equity strategies. Moderate-to-high turnover reflects the dynamic nature of convertible arbitrage, where position sizing adjusts based on delta movements, conversion probabilities, and relative value opportunities.

Steelhead Partners represents an established Seattle-based hedge fund with specialized expertise in convertible securities and event-driven strategies. Under Michael Johnston's leadership spanning over two decades, the firm has built institutional-scale capabilities in a complex but potentially rewarding investment niche. The extensive 13F filing history dating to the early 2000s enables analysis of equity positioning evolution across multiple market cycles, including periods of stress that tested convertible arbitrage strategies broadly. Key considerations include the specialized nature of disclosed holdings—which represent components of hedged structures rather than standalone directional positions. Platform users analyzing Steelhead Partners should recognize that Historical Track Record derived from 13F equity holdings provides partial insight into overall strategy performance. The disclosed positions reflect delta hedges and equity exposures that function within broader convertible structures, creating analytical complexity that distinguishes convertible arbitrage managers from traditional equity funds. Sharpe Ratio and risk-adjusted metrics calculated from disclosed holdings offer perspective on equity-side efficiency but may not capture the full risk-return profile of hedged convertible positions. Simulated Growth Chart visualization enables examination of disclosed equity evolution, though interpretation requires context regarding the hedging function these positions serve. Given Steelhead Partners' convertible arbitrage specialization, how might the disclosed equity positioning reflect changes in convertible issuance patterns, credit spread environments, and hedging requirements across different market regimes—and what does the evolution of sector exposure suggest about opportunity sets in the convertible market?

Steelhead Partners' convertible arbitrage approach produces a distinctive risk profile that differs substantially from directional equity strategies. When properly hedged, convertible arbitrage positions exhibit reduced correlation to broad equity markets, potentially providing diversification benefits within investor portfolios. The Volatility Profile of the overall strategy typically targets moderate levels through delta hedging that offsets equity price movements. However, the 13F-disclosed equity positions represent only one component of hedged structures, meaning disclosed holding volatility may not reflect total portfolio risk characteristics. Analyzing equity holdings in isolation provides incomplete insight into actual risk exposure. Historical risk considerations for convertible arbitrage strategies include: - Credit risk: Convertible bonds remain corporate obligations subject to issuer default - Liquidity risk: Convertible markets may experience liquidity withdrawal during stress periods - Hedging execution risk: Delta adjustments require ongoing rebalancing that may face execution challenges - Borrow availability: Short equity hedges depend on securities lending availability and costs Max Drawdown Depth analysis through the firm's extensive 13F history provides insight into equity-side positioning through various market regimes, though total fund drawdowns incorporate additional factors beyond disclosed holdings. The 2008 financial crisis proved particularly challenging for convertible arbitrage strategies broadly, testing risk management frameworks across the sector.
