# BlueMountain Capital Management: High-Level Overview
BlueMountain Capital Management is a diversified alternative asset management firm that specializes in credit-focused investment strategies[3][6]. The firm operates as a hedge fund manager and asset management company, offering solutions across structured finance, corporate and municipal credit, asset-backed finance, and private investment strategies[3][6].
The firm's investment philosophy centers on credit culture and complementary market solutions[1], with a track record of building substantial assets under management through disciplined strategy execution. At its peak in 2016, BlueMountain managed $23 billion in assets, demonstrating significant scale and investor confidence in its approach[3].
BlueMountain Capital Management was founded by Andrew Feldstein, who serves as co-founder, CEO, and Chief Investment Officer[3]. The firm built its reputation through successful credit investing, notably benefiting from gains in the London whale trading environment, which catalyzed significant growth in the early 2010s[3].
Between 2012 and 2013, the firm's assets under management surged from $12 billion to $18 billion, reflecting strong performance and investor demand[3]. Over the subsequent years, BlueMountain expanded its capabilities by launching five new strategies between 2012 and 2018, broadening its market reach and investment offerings[3].
On October 1, 2019, Assured Guaranty completed its acquisition of BlueMountain for approximately $160 million, with BlueMountain managing $18.9 billion in assets at the time[3]. Andrew Feldstein transitioned to serve as Chief Investment Officer and Head of Asset Management at Assured Guaranty while retaining his BlueMountain responsibilities[3].
In September 2020, the firm was rebranded as Assured Investment Management (AIM), operating as the asset management subsidiary of Assured Guaranty[3]. This transition reflected a strategic integration while maintaining the specialized investment strategies and market expertise that BlueMountain had developed[3].
BlueMountain's evolution reflects broader trends in alternative asset management: the consolidation of specialized investment managers into larger financial services platforms, and the growing institutional demand for sophisticated credit strategies. The firm's expertise in structured finance and municipal credit positioned it well within markets requiring deep technical knowledge and regulatory sophistication.
The acquisition by Assured Guaranty—a publicly traded financial services company—exemplifies how specialized asset managers create value through integration with larger platforms that can provide capital, distribution, and operational support. BlueMountain's rebranding as Assured Investment Management signals a strategic shift toward leveraging its parent company's strengths in municipal finance and structured credit markets[3].
