There's a little-known tech name on Josh Brown's Best Stocks list that's at the nexus of the data center buildout

MACOM Technology Solutions reported record quarterly revenue of $289.0M, up 22% year over year, with adjusted EPS of $1.09 versus $0.85 last year and a record 1.5x book-to-bill ratio. Management raised Q3 revenue guidance to $331M-$339M, above the $299.81M consensus, and lifted full-year data center growth guidance to over 60% from 35%-40%. The stock surged on the earnings update and has since consolidated near $367 after briefly approaching $400.

Analysis

MTSI is not just an AI beneficiary; it is a latency bottleneck beneficiary. When hyperscale capex shifts from “how many GPUs” to “how quickly can they talk,” the economic value moves upstream to high-frequency interconnect, and that tends to re-rate suppliers with a more specialized design win profile. The second-order effect is that the AI spend chain becomes less GPU-monocentric: networking, optical, and RF content per rack should keep expanding even if compute unit growth normalizes.

The magnitude of the guidance reset matters more than the beat itself. A move from mid-30s growth expectations to 60%+ implies the company is still in the steep part of its penetration curve, which usually extends the runway for multiple quarters even after the first rerate. That said, the stock has already discounted a lot of the story; the next leg likely depends on follow-through orders rather than headline guidance, so the tape becomes increasingly sensitive to any sign of digestion at hyperscalers or product mix pressure.

The defensible bear case is not demand collapse, but duration risk: when a component supplier re-rates this fast, the market starts pricing a clean execution path and underappreciates lumpy order timing. If data center customers are front-loading builds, near-term upside can be followed by a softer booking cadence in 1-2 quarters even while the secular story stays intact. That makes this more of a momentum-with-fundamentals trade than a set-it-and-forget-it compounder at these levels.

Relative to NVDA, MTSI is a quieter way to express AI infrastructure spend without paying peak narrative multiples on compute. The best risk/reward is likely on pullbacks into trend support rather than chasing upside gaps, because the stock now needs the market to keep rewarding evidence of breadth in AI infrastructure spending. If the next print confirms backlog conversion rather than just bookings, the move can extend; if not, the stock is vulnerable to de-rating before the long-term story breaks.

Key Decisions for Investors

• Buy MTSI on a pullback toward the 50-day moving average with a 2-3 month horizon; treat it as a momentum continuation setup with a favorable upside skew if bookings convert into revenue cleanly.
• Use a pair trade long MTSI / short a slower-growth semiconductor or industrial analog peer if available in the book; the thesis is relative multiple expansion for AI interconnect content versus mature end-market exposure.
• For tactical traders, consider a call spread in MTSI into the next earnings window to express continuation without owning full downside from a post-gap consolidation failure.
• If already long, de-risk partially into strength above prior highs and add only on confirmed support; this is a stock where execution misses can compress multiple points quickly after a vertical move.
