The Fund (Retail Class shares) returned -3.21% in the quarter, outperforming the benchmark Russell Midcap® Growth Index’s -6.35% return. The outperformance was primarily due to industry and stock selection, particularly in the industrials sector.

Fidelity Growth Strategies Fund stated the following regarding Comfort Systems USA, Inc. (NYSE:FIX) in its Q1 2026 investor letter:
“The fund’s outperformance of the Russell benchmark this quarter was driven primarily by industry selection, with stock selection also providing a modest boost. Stock picks and a large overweight in the industrials sector helped the most by far.
Looking at individual equities, our investments in several capital goods firms within industrials – including a non-benchmark stake in Sterling Infrastructure (+33%) and overweights in MasTec (+48%) and Comfort Systems USA, Inc. (NYSE:FIX) (+47%) – were among our top relative contributors. Comfort Systems USA handles electrical and mechanical wiring, as well as plumbing and piping, for commercial and industrial facilities.
What they all have in common is that each has seen their business skyrocket as a direct or indirect result of the huge investments now being made to build AI-capable data centers. We slightly trimmed the stake in each this quarter to manage the position size, but Comfort Systems and Sterling Infrastructure were the second- and third-largest fund holdings, respectively, as of March 31, and all three stocks were among our top-20 portfolio overweights.”
