Convertible Market in High Gear: A Look at What’s Under the Hood

Convertible securities offer growth exposure with a potential downside cushion, but their changing equity sensitivity makes active selection and management essential.

• Convertibles gained 25.66% over the period ending August 20, 2026, versus 20.09% for the S&P 500, while providing both an equity-conversion option and bond-like coupon and maturity features.
• Global issuance reached $144.4 billion through July 2026, putting the market on track to exceed the 2025 record of $167 billion; Alphabet completed the largest single convertible issuance ever.
• Growth companies, particularly AI issuers, are strongly represented, although the market also spans defense and aerospace, asset management, online retail, and pharmaceuticals.
• AI-related convertibles currently have higher equity sensitivity than other parts of the market, increasing the overall market’s equity exposure and the risk of sharper short-term swings.
• The author expects continued opportunities from AI, defense, and other growth themes but warns that upcoming midterm elections could increase volatility through their effects on fiscal policy and the economy.

Takeaway: Convertibles can complement equities or traditional fixed income, but investors should use a strategic, long-term allocation and active management because security characteristics and risks vary materially.
