Convertible bond issuance hits a record, shifting the task from whether to own to which to pick. Here's how to evaluate the structures, from conversion premium to call risk.
Convertible bond issuance has hit a record this year, and the question for investors has shifted from whether to own convertibles to which ones to pick. The market is awash with supply, much of it from companies that would not have qualified for a convertible a few years ago. That changes the calculus.
A simple read goes like this: convertibles offer equity upside with a bond floor, so more supply means more opportunity. In past cycles, much of that supply came from distressed companies – firms that could not access straight debt and used convertibles as a last resort. The risk was real. The bond floor did little to protect against default.
This cycle is different. Many of the companies issuing now have quality fundamentals: positive cash flow, strong revenue growth, and manageable leverage. They are raising capital to fund expansion, not to survive. The convertible structure gives them lower coupon costs than a straight bond, and investors get exposure to equity-like upside with a cushion. The investment team behind the note sees this as a chance to invest in exciting growth companies with less downside risk.
The better read starts with the instrument mechanics. A convertible's sensitivity to the equity depends on the conversion premium, the maturity, and the volatility. A high premium means the bond behaves more like straight debt; a low premium means it tracks the stock. In a record market, the dispersion between these profiles widens. Some convertibles will offer little equity participation, others will be almost fully equity-linked. The investor has to match the structure to their conviction on the stock.
There is also the call risk. Many recent convertibles are callable after a short period, often six months to a year. If the stock rallies, the issuer can force conversion, capping the upside. That is not necessarily bad – the investor gets the conversion value – but it means the bond's duration shrinks precisely when equity exposure is most valuable.
The market has grown so fast that liquidity has not kept up. Some of the new issues are small, below $200 million, and trade infrequently. That creates a spread cost for any position that needs to adjust quickly. The investor who picks a liquid issuer with a reasonable size has an edge.
The final piece is valuation. Convertible bonds now yield around 2.5% on average, a level not seen since before the rate hike cycle. That yield acts as a carrying cost buffer if the equity stalls. If the stock falls, the bond floor provides support, only if the credit holds. With quality companies, that floor is credible.
The investment team's approach is to focus on issuers where the convertible is not a last resort. That means companies with strong margins, visible growth, and a clear use for the capital. The record market offers more of those than ever.
The next real test for these bonds will come when the equity volatility that drove issuance subsides. Until then, picking spots means reading each structure, not just the ticker.
