Calamos Convertible & High Income Fund Q2 2026 Commentary

Calamos Convertible & High Income Fund returned 24.62% on NAV and 28.01% on market price for the quarter ended June 30, 2026. Performance was driven by security selection and an overweight allocation to information technology, with tech hardware/storage/peripherals and semiconductor materials/equipment contributing positively. Relative to the comparator index, real estate selection was a headwind as data center REITs and real estate services detracted from relative performance.

Analysis

The signal is less about the fund itself and more about where embedded equity optionality is still being paid for: convertibles tied to hardware/semis are acting like a leveraged claim on the AI capex cycle with less downside than outright equity. That tends to reward issuers and arbitrage desks first, then the secondary market if volatility stays contained; the real loser is capital-intensive real estate, especially data-center exposure, where investors are starting to separate revenue growth from economics of power, cooling, and refinancing.

Near term, this is primarily a 1-3 month relative-value setup, not a broad risk-on green light. If tech earnings hold and rates stay range-bound, tech-heavy convertibles should keep outperforming plain high-yield and rate-sensitive REITs; if the 10-year backs up or semis guide cautiously, the convexity premium can compress quickly because convertibles lose both equity support and spread support. The 6-18 month structural issue is that AI infrastructure winners may shift from landlords to owners of scarce compute and semis, which would pressure data-center REIT multiples even if fundamentals look stable.

Contrarian view: consensus may be over-crediting the durability of tech upside inside convertible baskets while underestimating how quickly market-price strength can fade if discount narrowing, not NAV growth, is doing the work. The key missing data is whether distribution coverage and portfolio duration are improving; without that, strong market price performance is fragile. Falsifiers are simple: a sustained move higher in long rates, a semis earnings reset, or evidence that data-center lease spreads are holding up despite capex inflation.

Key Decisions for Investors

• Long CWB / short IYR for 1-3 months: express tech-convertible convexity versus rate-sensitive real estate. Best entry is on any 1-2% pullback in CWB; thesis weakens if the 10Y Treasury falls 50 bps and REIT guidance stabilizes.
• Overweight SOXX versus VNQ in equity sleeves over the next quarter. This captures the same second-order trade with cleaner liquidity; cut the pair if semiconductor order books decelerate or rates drop fast enough to re-rate REITs.
• Use XLK vs. DLR/EQIX only as a tactical short-REIT hedge, not a core short. Data-center names can outrun the macro if leasing and power access remain tight, so wait for any rally on AI enthusiasm to initiate.
• Watch the convertible pipeline: if tech issuance reopens over the next 1-3 months, add exposure to CWB/convert arb strategies. If issuance dries up while prices keep rising, that is a sign the move is becoming purely momentum-driven and should be faded.
• If the fund trades at a meaningfully tighter premium to NAV, consider fading the market-price strength. The market is likely pricing the right sector exposure, but not necessarily a persistent improvement in portfolio quality.
