“These gains were partially offset by semiconductor holdings Allegro MicroSystems and Onto Innovation, which gave back some first-half gains as the AI semiconductor trade unwound despite generally solid fundamentals.”
Allegro Microsystems, Inc. - September 2026
“1. Allegro Microsystems, Inc. (ALGM) ALGM makes sensing and power semiconductors, primarily for automotive and industrial customers. We initiated a position because vehicle electrification, driver- assistance systems and other electronic features are increasing chip content per vehicle.”
Allegro Microsystems, Inc. - September 2026
“Allegro MicroSystems (Information Technology, Special Situation) - Added Allegro MicroSystems declined amid broad weakness in automotive semiconductors, where concerns around end-market demand and inventory normalization pressured the group. We increased the position during the weakness as we remained constructive on the company's long-term content growth and differentiated exposure within automotive electronics.”
Allegro Microsystems, Inc. - August 2026
“In both cases we saw share price weakness as an opportunity and added to our positions.”
Allegro Microsystems, Inc. - July 2026
“After an incredible run over the last twelve months, stocks related to the AI capex boom faltered somewhat in July. Heroic levels of investor optimism crashed against the cold reality of quarterly earnings, leading to sharp declines in share prices across the main beneficiaries of this trend. Investment style indicators swung sharply away from large cap growth to small cap and value as investors rushed to readjust. Although there was no notable slowdown in capital investment in the AI sector, background noise of improving, lower-cost Chinese models and a shift in sentiment following the weak performance of SpaceX post-IPO, all helped to add some caution to a previously euphoric sector. Although the fund's exposure to the mega-cap AI companies is limited to Samsung Electronics, that did not mean we were entirely shielded from the melee. Some of our more specialist companies that are exposed to the semiconductor capex cycle were also impacted and this weighed on the Fund over the month. Although uncomfortable in the short term, we continue to see a strong multi-year runway for these businesses and continue to opportunistically add on weakness. The most significant impact was to MKS, the US-listed manufacturer of specialist semiconductor and electronics-related tools and equipment. Shares sold off after a strong run, in sympathy with the AI sell-off, despite no specific news flow from the company. The same was true for US- listed sensor and motion control company Allegro Microsystems.”
Allegro Microsystems, Inc. - June 2026
“Portfolio Performance The ClearBridge SMID Cap Growth Strategy generated double-digit absolute returns but underperformed the soaring Russell 2500 Growth Index benchmark during the quarter, with underexposure to the highest-beta AI infrastructure winners as well as weakness in health care and consumer discretionary sectors more than offsetting strong contributions from several AI-related and biotechnology holdings. Information technology (IT) was a meaningful source of relative weakness despite strong performance from several individual holdings. Semiconductor companies including Allegro MicroSystems and Lattice Semiconductor, along with networking and semiconductor capital equipment providers such as Coherent, Credo Technology and Onto Innovation, benefited from demand tied to AI infrastructure, semiconductor cycle improvement, automation and cutting-edge AI applications.”
