In the second quarter of 2026, the Calamos Growth And Income Fund demonstrated a robust performance, surpassing the S&P 500 Index. This strong showing is largely attributed to the fund's strategic focus on artificial intelligence infrastructure, which continues to be a significant engine for market growth. The US economy is currently experiencing a sustained mid-cycle expansion, bolstered by supportive fiscal policies, a push for deregulation, consistent labor demand, and an unprecedented surge in capital expenditure driven by AI advancements. However, despite these favorable conditions, the investment landscape exhibits a narrow leadership, prompting the fund to adopt a cautious, risk-aware approach.
The US economic expansion is projected to continue, marking a mid-cycle phase characterized by resilience and growth. Key factors underpinning this outlook include ongoing fiscal stimulus, a pro-growth regulatory environment, and robust demand in the labor market. A notable aspect of this expansion is the substantial capital investment in artificial intelligence, which not only fuels technological progress but also contributes significantly to corporate earnings. For instance, AI infrastructure accounted for approximately 60% of the S&P 500's earnings growth during the recent quarter, highlighting its pivotal role in market dynamics.
However, the concentrated nature of market leadership, where a few dominant players heavily influence overall performance, necessitates a judicious investment strategy. While maintaining exposure to high-growth areas like AI infrastructure and semiconductors, the fund has proactively managed risk by adjusting positions in overextended assets. This involves scaling back on highly valued stocks and diversifying investments into other sectors, such as financials and industrials, to mitigate potential vulnerabilities associated with narrow market leadership.
The fund's convertible strategy played a crucial role in its Q2 2026 performance. By investing in convertible securities, particularly within AI-related companies like Seagate and Bloom Energy, the fund effectively capitalized on equity upside while simultaneously reducing downside exposure. This hybrid approach allowed for participation in the growth of innovative companies while offering a measure of protection, contributing to the fund's outperformance relative to the broader market index.
The second quarter of 2026 saw the Calamos Growth And Income Fund navigate a dynamic market environment successfully. Its performance underscores the benefits of a balanced investment approach that leverages growth opportunities, especially in transformative technologies like AI, while actively managing risks stemming from market concentration and economic cycles. The fund's ability to adapt and strategically reallocate assets positions it well for future market shifts, ensuring continued pursuit of long-term value creation.
