Carillon Tower Advisers has highlighted Teradyne, Inc. as a top performer in its Carillon Eagle Mid Cap Growth Fund fourth-quarter 2025 investor letter. The semiconductor testing equipment manufacturer emerged as one of the leading contributors to the fund’s performance during a challenging period for midcap growth stocks. According to the investment management company, Teradyne stock closed at $304.22 per share on March 03, 2026, reflecting strong momentum in the semiconductor testing equipment market.
The company’s remarkable performance included a one-month return of 13.06% and an impressive 176.04% gain over the previous 52 weeks, bringing its market capitalization to $47.627 billion. Carillon Eagle Mid Cap Growth Fund attributed Teradyne’s success to very strong quarterly results driven by robust demand for test equipment used with artificial intelligence-related semiconductors.
Midcap Growth Stocks Face Mixed Quarter
The fourth quarter of 2025 presented challenges for midcap growth investors, with the Russell Midcap Growth Index declining 3.70% during the period. In contrast, the Russell Midcap Value Index posted a positive return of 1.41%, highlighting the divergence between growth and value strategies. Materials led sector performance in the growth index with a 17.51% return, though its limited weighting restricted its overall contribution.
Healthcare and real estate were the only other sectors posting positive returns in the quarter, rising 1.13% and 0.24% respectively. Despite the challenging fourth quarter, midcap stocks delivered positive annual returns in 2025, though they trailed the strong performance seen in 2024. The Russell Midcap Growth Index finished the year up 8.66%, while the Russell Midcap Value Index outperformed with an 11.04% return.
Teradyne Benefits from AI Semiconductor Demand
According to Carillon Eagle Mid Cap Growth Fund’s investor letter, Teradyne’s strong performance stemmed from exceptional demand for testing equipment used with AI-related semiconductors. The company reported very strong quarterly results that exceeded market expectations and demonstrated the critical role of testing equipment in the semiconductor supply chain. Additionally, the fund noted potential market share gains that could further support Teradyne’s revenue growth prospects in 2026.
The semiconductor testing equipment supplier has positioned itself as a key beneficiary of the ongoing artificial intelligence boom. As chip manufacturers ramp up production of AI-specific processors and accelerators, demand for sophisticated testing equipment has surged correspondingly. However, the company faces typical cyclical risks associated with the semiconductor industry and potential competitive pressures.
Hedge Fund Holdings and Market Position
Institutional interest in Teradyne has strengthened considerably, with 77 hedge fund portfolios holding the stock at the end of the fourth quarter, up from 58 in the previous quarter. This increase in hedge fund ownership reflects growing confidence in the company’s growth trajectory and market position. Meanwhile, Carillon Tower Advisers anticipates a favorable year ahead for equity markets overall, identifying opportunities across cyclicals, healthcare, information technology, financials, and consumer spending sectors through 2026.
The investment firm’s positive outlook for 2026 suggests continued support for semiconductor-related stocks, particularly those exposed to AI infrastructure buildout. Nevertheless, the utilities sector recorded the highest absolute return in the midcap growth index for 2025 at 29.40%, demonstrating the breadth of opportunities available to investors.
The outlook for Teradyne and the broader semiconductor testing equipment market remains tied to AI chip demand trends and overall semiconductor capital expenditure cycles. Market participants will likely monitor upcoming quarterly results for confirmation of sustained growth momentum and potential market share expansion mentioned in the fund’s assessment.
