Glenn Russell Dubin is one of the industry’s most experienced hedge fund managers, best known as the co-founder of Highbridge Capital Management, a multi-strategy investment business he founded with Henry Swieca in 1992. Before being bought by JPMorgan Chase in 2004, the firm quickly rose to prominence as one of Wall Street’s most sophisticated hedge funds. As of March 2024, Highbridge Capital manages more than $7.1 billion in discretionary assets and has a focused exposure to growth industries.
Dubin has long been involved in basic research and multi-asset investing through Highbridge and his private investment firm, Dubin & Company. His portfolio demonstrates a high-conviction strategy, with the top ten holdings accounting for more than 40% of reported 13F equities. Dubin’s top stock picks frequently coincide with broader macroeconomic themes, such as monetary easing, capital market expansion, and industrial revival, making them excellent bets for long-term investors looking for asymmetric risk-reward ratios.
The background for these investments is especially attractive. Financial markets rebounded strongly in 2024, with financial equities up more than 30% by the end of the year, owing to lower inflation, lower interest rates, and strong investor sentiment. Even if the United States’ GDP growth is expected to fall from 2.7% in 2024 to 1.5% in 2025, hopes of Fed rate cuts and a more stable regulatory environment are keeping financial industry momentum alive. Meanwhile, growing corporate refinancing needs and record-high consumer debt are steering capital into private credit and asset-backed lending—areas where Highbridge has traditionally excelled.
The industrial sector is also experiencing a significant revival, with a 26% increase in 2024 driven by demand for reshored manufacturing, clean energy buildout, and infrastructure construction. With only a quarter of the $1.9 trillion in planned North American infrastructure projects underway, there is still enormous growth potential. At the same time, reduced interest rates are expected to boost housing activity, and aerospace demand is expected to rise as airlines revamp their aged fleets. These macroeconomic drivers continue to provide appealing entry points for cyclical names with long-term upside.
Tariff concerns have increased volatility in the equity markets, particularly in light of proposed higher tariffs on steel and aluminum imports. However, other investors see this as a temporary disruption that could eventually benefit domestic manufacturers and capital goods industries. In reality, leading market commentators argue that predictions of a fresh wave of trade protectionism are exaggerated, with underlying fundamentals remaining strong across major value industries.
In that scenario, this may be a good time to follow experienced managers such as Glenn Dubin. As markets reset and valuations in banking and industrial stocks decline from their 2024 highs, the opportunity to purchase into structurally good companies at a discount is wide open. Highbridge Capital’s recent bets indicate trust in sectors that are not only rebounding but evolving, and these top stock picks might provide considerable upside as the market rebalances in 2025.
