Marvell Technology Inc. (Marvell Technology (MRVL)) shares climbed nearly 3% on Tuesday, riding a broader market rally and a fresh vote of confidence from KeyBanc. The bank maintained its Overweight rating and boosted its price target from $385 to $400, pointing to big wins in the custom AI chip space.

Analyst John Vinh highlighted growing momentum in Marvell's custom AI silicon business. He expects Amazon.com Inc. (Amazon (AMZN)) to ramp its Trainium 3 program in the second half of 2026, with Trainium 3 Lite volumes increasing into 2027. Vinh also sees Marvell supplying a variant of Amazon's next-generation Trainium 4 accelerator using network processing offload (NPO) technology.

But the really big news is with Alphabet Inc. (Alphabet (GOOGL)). KeyBanc says Marvell has secured a design win for Google's LPU, codenamed Merope, which is expected to launch in 2028 or 2029. The firm estimates shipments of 2 million to 3 million units, representing $10 billion to $12 billion in revenue over the program's lifecycle. That's a lot of chips — and a lot of revenue.

Technical Picture Remains Mixed

Marvell's long-term trend is still your friend. The stock trades about 30.5% above its 100-day simple moving average and roughly 74% above its 200-day simple moving average. A golden cross formed back in October 2025 continues to support the bullish narrative.

But the short-term picture? Less pretty. Marvell is trading about 16.2% below its 20-day simple moving average and 4.6% below its 50-day simple moving average. That suggests the stock is still working through a pullback rather than starting a fresh breakout. Momentum indicators also flash caution — the MACD is below its signal line, and the histogram is negative, meaning buying momentum has weakened.

Traders are watching resistance near $233.85, which aligns with the 50-day simple moving average. Immediate support sits around $222.96. So the stock is in a bit of a no-man's land right now.

Earnings and Analyst Outlook

Marvell is expected to report quarterly results on Aug. 27. Analysts are looking for earnings of 87 cents per share on revenue of $2.70 billion, compared with 67 cents per share and $2.01 billion in revenue a year earlier. That's solid growth, but the stock trades at about 74.8 times earnings — a premium valuation that leaves little room for error.

Wall Street still loves it, though. The consensus is a Buy, with an average price target of $270.83. Recent analyst actions include KeyBanc's raise to $400, RBC Capital Markets maintaining an Outperform with a $360 target on July 7, and UBS raising its Buy target to $340 on June 29.
