In the initial quarter of 2026, the Invesco Main Street Mid Cap Fund's Class A shares recorded a return of -1.98% at net asset value, contrasting with the Russell Midcap Index's gain of 1.29%. This underperformance was mainly influenced by specific stock choices within the information technology, healthcare, and consumer staples sectors. However, this was partially mitigated by stronger selections in the financials, consumer discretionary, and real estate sectors. During this period, mid-cap equities generally showed better performance than the broader market, as investor focus shifted from large-cap stocks. The fund's management maintained its strategic approach, keeping its market exposure closely aligned with the index, with notable investments such as Lumentum expected to capitalize on artificial intelligence advancements.

During the first three months of 2026, the Invesco Main Street Mid Cap Fund's Class A shares experienced a downturn of 1.98% on a net asset value basis, failing to match the Russell Midcap Index's positive return of 1.29%. An in-depth analysis revealed that the primary factors contributing to this shortfall were stock-picking decisions within the information technology, healthcare, and consumer staples industries. Conversely, superior stock selection in the financial, consumer discretionary, and real estate sectors provided some counterbalance. This quarter was characterized by a broader market trend where mid-capitalization stocks outpaced their larger counterparts, signifying a rotation of market leadership away from mega-cap companies. Despite the fund's relative underperformance, its investment managers adhered to their established strategy, ensuring that the fund's positioning largely mirrored that of its benchmark index. A key highlight of their portfolio strategy included investments in companies like Lumentum, which is anticipated to achieve above-average earnings growth, propelled by the expanding influence of artificial intelligence. This strategic foresight underscores the fund's long-term vision, even amidst short-term fluctuations.

The fund's overall portfolio remained consistent with its benchmark, demonstrating a disciplined approach to sector weightings, typically staying within a 3% variance of the Russell Midcap Index. This strategy reflects a commitment to valuation discipline and a focus on enterprises characterized by robust leadership and distinct competitive advantages. Recent adjustments to the portfolio, including new holdings in companies such as Hyatt, Ross Stores, Devon Energy, Evercore, Lumentum, and Hershey, aim to capitalize on current operational momentum and the burgeoning opportunities presented by AI. These additions are strategically selected to enhance the fund's growth prospects. Concurrently, positions in companies like Astera Labs and Carlyle were exited, reflecting active risk management and a refined conviction in the remaining holdings. These decisions are integral to positioning the fund for sustained performance in a dynamic market environment.

In summary, the first quarter of 2026 presented a mixed picture for the Invesco Main Street Mid Cap Fund. While the fund's Class A shares lagged the Russell Midcap Index, with specific sectors notably impacting returns, the broader shift towards mid-cap outperformance indicates a changing market landscape. The fund's steadfast investment philosophy, coupled with targeted adjustments to its holdings, aims to leverage long-term growth trends, particularly those driven by technological innovation like artificial intelligence. Management's consistent sector exposure and focus on fundamentally strong companies underscore a deliberate strategy to navigate market complexities and pursue future value creation for investors.
