Summary Points:

  • From knockout issuance to returns, the global convertible market delivered in a quarter what we’d be happy to see in a year.
  • Calamos Global Convertible Fund (CXGCX) gained 14.5% for the quarter, outperforming the FTSE Global Convertible Index, up 13.8%, as well as the MSCI World Index, up 13.9%.
  • We are finding many opportunities in the new issuance market to rebalance and lock in gains.

The second quarter saw plenty of ups and downs, but investors ultimately managed to shrug off whatever came their way, from war and geopolitics to the prospect of interest rates rising rather than falling under a new Federal Reserve chair. The global convertible market soared as investors cheered continued strength in corporate earnings, particularly in the AI complex, and a ceasefire agreement between the US and Iran, which boosted expectations that inflation would fall alongside energy prices.

The quarter brought record-breaking levels of new convertible issuance. Alphabet—a first-time issuer—led the way with a $19.3 billion mandatory convertible issue, the largest on record. While Alphabet’s monster deal may have grabbed most of the headlines, it was just one of a flurry of companies to seek growth capital from the convertible market. When all was said and done, companies around the world issued $83.6 billion during the quarter, bringing year-to-date totals to $137.5 billion. For perspective, this half-year total already surpasses the calendar year totals of all but six of the past 28 years.

Growth Capital for Growth Companies: Booming Issuance in Global Convertibles

This issuance environment gave us plenty of opportunities. This included leaning into the new issuance market to sell in-the-money paper and buy at-the-money paper. But we’re also being selective about company fundamentals and conscious of position size. As we’ve discussed in the past, convertibles vary in their levels of equity sensitivity and fixed-income sensitivity. The greater the equity sensitivity, the greater the convertible’s exposure to both the upside and downside of its underlying equities. Mandatory convertibles—like Alphabet’s—are a different animal than traditional convertible bonds. They tend to be more equity-like, so we factor this into our overall portfolio construction process. But understanding these sorts of trade-offs is our bread and butter, and we believe our experience makes the difference.

Our overall allocations reflect our bottom-up focus—in other words, it’s always about finding good names with good structures. Information technology companies make up roughly one-third of the portfolio as of quarter-end (slightly less than the benchmark weight), followed by consumer discretionary at about one-fifth (a significant overweight), with industrials and health care next. Regionally, US issues make up about two-thirds of the fund, followed by Emerging Asia at about one-sixth.

Where to from here?

We see many positives on the horizon. We’re optimistic about the issuance momentum in the market; as we’ve discussed in the past, there tends to be a “follow-the-leader” theme in convertible issuance, and the decision of mega-caps like Alphabet and Oracle to issue convertibles could be a powerful catalyst for other large-cap companies to follow suit, further enhancing the diversity of the market as a whole. We’re optimistic about many of the convertible structures in the market today.

Still, we’re being prudent. The endgame of the war with Iran isn’t obvious, US midterms will contribute to investor anxiety, and we expect the newsfeed to continue whipsawing investors as it has over recent months. We’re also aware that we could already be in a late-cycle environment, and it’s essential to have the right risk-reward ahead of a turn.

Not every quarter will be like this second quarter, but as active, experienced managers, we don’t need a shoot-the-lights-out market to be optimistic about what’s ahead for Calamos Global Convertible Fund.

There can be no assurance that the Fund(s) will achieve its investment objective. Your investment in the Fund(s) is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. The risks associated with an investment in the Fund(s) can increase during times of significant market volatility. The Fund(s) also has specific principal risks, which are described below. More detailed information regarding these risks can be found in the Fund’s prospectus.

Alternative investments may not be suitable for all investors. The fund takes long positions in companies that are expected to outperform the equity markets, while taking short positions in companies that are expected to underperform the equity markets and for hedging purposes. The fund may lose money should the securities the fund is long decline in value or if the securities the fund has shorted increase in value, but the ultimate goal is to realize returns in both rising and falling equity markets while providing a degree of insulation from increased market volatility.

Calamos Structured Protection ETFs. There is no guarantee the Fund will be successful in providing the sought-after protection. The outcomes that the Fund seeks to provide may only be realized if you are holding shares on the first day of the Outcome Period and continue to hold them on the last day of the Outcome Period, approximately one year. There is no guarantee that the Outcomes for an Outcome Period will be realized or that the Fund will achieve its investment objective. If the Outcome Period has begun and the Underlying ETF has increased in value, any appreciation of the Fund by virtue of increases in the Underlying ETF since the commencement of the Outcome Period will not be protected by the Buffer, and an investor could experience losses until the Underlying ETF returns to the original price at the commencement of the Outcome Period. Fund shareholders are subject to an upside return cap (the "Cap") that represents the maximum percentage return an investor can achieve from an investment in the funds' for the Outcome Period, before fees and expenses. If the Outcome Period has begun and the Fund has increased in value to a level near to the Cap, an investor purchasing at that price has little or no ability to achieve gains but remains vulnerable to downside risks. Additionally, the Cap may rise or fall from one Outcome Period to the next. The Cap, and the Fund's position relative to it, should be considered before investing in the Fund. The Fund's website, www.calamos.com, provides important Fund information as well information relating to the potential outcomes of an investment in a Fund on a daily basis.

The principal risks of investing in the Calamos Autocallable Income ETF include: autocallable structure risk, contingent income risk, early redemption risk, barrier risk, authorized participant concentration risk, calculation methodology risk, cash holdings risk, correlation risk, costs of buying and selling fund shares, counterparty risk, credit risk, derivatives risk, equity securities risk, index risk, interest rate risk, investment in a subsidiary, laddered portfolio risk, liquidity risk, market maker risk, market risk, new fund risk, non-diversification risk, premium-discount risk, secondary market trading risk, swap agreement risk, tax risk, trading issues risk, valuation risk, and volatility target index risk.

Autocallable Structure Risk–The Fund’s returns are correlated to the performance of a synthetic portfolio of autocallable notes tracked by the Laddered Autocall Index. Autocallable notes have specific structural features that may be unfamiliar to many investors:

–Contingent Income Risk: Coupon payments from the Autocalls are not guaranteed and will not be made if the Underlying Index falls below the Coupon Barrier on observation dates. This means the Fund may generate significantly less income than anticipated during market downturns.

–Early Redemption Risk: Autocalls in the Portfolio may be called before their scheduled maturity if the Underlying Reference Index reaches or exceeds the Autocall Barrier on observation dates. This automatic early redemption could force reinvestment of that portion of the portfolio at lower rates if market yields have declined.

General Economic Conditions and Recent Events The value of the Funds’ or Alternative Funds’ investments may increase or decrease in response to expected, real or perceived economic, political or financial events in the US or global markets. The frequency and magnitude of such changes in value cannot be predicted. Certain securities and other investments held by the Fund or Alternative Funds may experience increased volatility, illiquidity, or other potentially adverse effects in response to changing market conditions, inflation/deflation, changes in interest rates, lack of liquidity in the bond or equity markets, volatility in the equity markets. US or global markets may be adversely affected by uncertainties and events in the US and around the world, such as major cybersecurity events, geopolitical events (including wars, terror attacks, natural disasters, spread of infectious disease (including epidemics or pandemics) or other public health emergencies), social unrest, political developments, and changes in government policies, taxation, restrictions on foreign investment and currency repatriation, currency fluctuations and developments in the laws and regulations in the US and other countries, or other political, regulatory, economic and social developments, and developments that impact specific economic sectors, industries or segments of the market.
