CHI To CHY: Swap Into The Cheaper Calamos Convertible Twin

CHI trades at a 1.88% premium while CHY trades at a 3.86% discount, a 5.74-percentage-point spread roughly 1.5 standard deviations above its one-year average. Despite a 0.999 correlation in daily NAV moves, swapping CHI for CHY would capture about 5.7 points of discount and increase yield on price from 9.58% to 10.05%.

Analysis

This is primarily a relative-value and fund-flow dislocation, not a change in underlying credit exposure. If portfolio overlap, leverage, fees, distribution policy and liquidity are sufficiently close, CHY offers a cheaper market-price entry than CHI; the quoted yield advantage is largely a discount-to-NAV effect, not evidence of higher portfolio income. It should not be treated as a free carry pickup: distributions may differ in sustainability or composition, and market discounts can widen independently of NAV.

The 5.74-point gap being about 1.5 standard deviations above its one-year average supports mean-reversion interest, but is not by itself an extreme signal. Over days, price action will likely be driven more by CEF flows and liquidity than by the nearly identical NAV moves. Over 1–3 months, distribution disclosures, credit-market volatility and relative fund flows are plausible convergence catalysts. Over 6–18 months, persistent differences in expenses, leverage, liquidity or distribution coverage could justify a durable discount differential.

The contrarian risk is assuming NAV correlation guarantees price convergence: it does not. CHI’s premium could persist, or CHY’s discount could widen in a risk-off credit tape. Verify current holdings overlap, leverage, expense ratios, distribution coverage/composition, trading depth and short availability before sizing a pair.

Key Decisions for Investors

• Consider a staged long-CHY/short-CHI relative-value position only after confirming comparable portfolio exposure, leverage, fees and distribution economics. The thesis is spread convergence, not a directional credit bet; size for further discount widening and include borrow, bid-ask and distribution costs.
• For holders unwilling or unable to short CHI, consider switching from CHI to CHY only after checking liquidity and tax consequences. The higher quoted yield on CHY’s market price is not, on its own, evidence of better underlying income or distribution quality.
• Use a 1–3 month catalyst watch: compare monthly NAV and market-price returns, fund flows, distribution announcements and discount changes. Do not add solely because the gap widens if NAV behavior or fund disclosures begin to diverge.
• Falsify or reduce the convergence thesis if updated holdings, leverage, expenses or distribution coverage show a material structural disadvantage for CHY, or if the relative discount widens alongside deteriorating credit conditions rather than isolated fund-level flows.
