Carillon Chartwell Small Cap Growth Fund: Q1 2026 Portfolio Movers

The information technology sector was among the portfolio's strongest performers in Q4, helped by a sharp ramp in Coherent's optical transceiver sales and strong growth in networking. MACOM Technology Solutions' strong third-quarter earnings eased investor concerns about margin volatility, supporting a fourth-quarter rebound. Overall tone is constructive for semiconductor and networking-related names, though the article is primarily a performance update rather than a major market-moving event.

Analysis

The key takeaway is that this is less a generic “AI/tech” tape and more a proof point that optical supply is still the bottleneck value pool. If transceiver demand is improving into a better mix and higher utilization, the second-order winner is not just the module vendor but also adjacent networking OEMs and hyperscale capex names that benefit from faster cluster buildouts; the loser is any competitor still dependent on price cuts to defend share. That usually shows up with a lag of 1-2 quarters as order visibility improves and buyers become less willing to delay deployments.

For MTSI, the market likely stopped penalizing execution risk faster than it should have. Margin volatility in this space is often a timing problem, not a structural problem, and when investors regain confidence the re-rating can be sharp because the names are typically owned for growth but valued like cyclicals. The important question over the next 1-3 quarters is whether the current rebound is driven by sustainable mix improvement and pricing discipline, or simply a cleaner comparison after a noisy period.

The contrarian risk is that consensus may be extrapolating a narrow earnings beat into a broader semiconductor upcycle. If hyperscaler spending pauses, inventory at channel customers could normalize quickly and expose how much of the recent strength is timing rather than true end-demand acceleration. In that scenario, the more levered names would underperform first, while the best-positioned suppliers with visibility into multi-quarter optical demand should hold up better.

Key Decisions for Investors

• Maintain a tactical long COHR into the next 4-8 weeks, but size it as a momentum-with-fundamentals trade; upside is continued multiple expansion if optical order flow remains tight, while the clean stop is any evidence of lead-time compression or buyer deferment.
• Buy MTSI on pullbacks over the next 1-2 months rather than chasing strength; the setup favors a re-rating if margin consistency persists, but risk/reward worsens sharply if the market decides the quarter was just a noise reduction event.
• Pair trade: long COHR / short a weaker networking or optical peer with more execution risk for 1-2 quarters; the trade expresses relative demand strength and reduces beta to the broader semi cycle.
• Use call spreads rather than outright equity for COHR if positioning is crowded; the thesis is a 2-3 month re-rate, but options cap downside if the market rotates away from capex beneficiaries.
