The massive semiconductor rally is entering its third month, and it seems anything connected to semiconductors and data centers is going parabolic.

While watching stocks go straight up is exciting, rallies like this can't last forever, and eventually the true winners will be separated from those that just rode the market's coattails. Figuring which stock is which is crucial, which is why we've gone over the semiconductor industry with a fine-toothed comb.

Here are the five rallying chip stocks with the fundamentals to keep rallying.

Micron Technology

Micron (NASDAQ:MU) was the catalyst for the latest semiconductor upside move when UBS raised its price target on MU shares to $1625, nearly triple its previous target. UBS analyst Timothy Arcuri says Micron should be valued like a critical AI infrastructure company and not a cyclical memory stock.

The stock responded with a 20% gain in a single day, driving the company's market cap above $1 trillion for the first time ever. Micron is one of three firms capable of producing large-scale quantities of high-bandwidth memory (HBM), along with Samsung and SK Hynix.

Recent earnings have backed up the bullish new target: the company grew revenue nearly 200% year-over-year (YoY) in Q2 2026 with record gross margins over 75%, and its backlog is filled through 2027. But despite its recent performance, MU still trades at just 9 times forward earnings.

MU shares had strong upward momentum before the UBS price hike, but the new target has sent the stock into a new stratosphere. However, despite the parabolic gains, the Relative Strength Index (RSI) and Moving Average Convergence Divergence (MACD) indicators don't show an overbought stock. 

Wolfspeed Inc.

Wolfspeed (NASDAQ:WOLF) has emerged from its Chapter 11 restructuring as a leaner, more focused company with a clean balance sheet and AI catalysts. The company has a $3.1 billion market cap and now sits on $1.3 billion in cash and short-term investments, providing the runway for management's proposed turnaround.

Wolfspeed's silicon carbide and gallium nitride products are becoming crucial to the semiconductor supply chain, and these manufacturing assets can now be put to use in the fast-growing data center industry. The company still needs to execute its turnaround, but the stock's 230% year-to-date (YTD) gain shows that investors have confidence in the turnaround plan. The company reported a smaller-than-expected loss during its May 5 earnings release, and the data center segment grew 30% sequentially.

WOLF shares have spent the last few weeks consolidating following the post-earnings pop, and actually pulled backed 20% last week. But this is likely a healthy correction after the stock rose well above trend and pushed the RSI into overbought territory. The uptrend remains strong with the 50-day moving average above the 200-day moving average, and the RSI is no longer overbought.

Marvell Technology Inc.

Marvell Technology (NASDAQ:MRVL) also exploded this spring, going from $75 to over $200 in less than three months. Marvell has a seat at the big boys' tables thanks to a lucrative partnership with NVIDIA, which includes a $2 billion investment. And after reporting fiscal Q1 2027 earnings last week, more stock gains could be on the horizon. Marvell reported record revenue of $2.42 billion, up 28% YoY, amid soaring data center demand. The data center segment pulled in $1.8 billion in fiscal Q1, and management relayed highly optimistic guidance for both 2027 and 2028, including 55% data center growth in fiscal 2028.

Marvell occupies a specific niche in the data center networking market, but also has legacy analog business segments that differentiate it from competitors like Broadcom. MRVL shares are up more than 150% in the last quarter alone, and the uptrend since April has been orderly, with little volatility. The stock has been moving upward in a tight price channel, which has prevented technical indicators like the RSI and MACD from reaching overbought levels. It also received a series of price target boosts following the fiscal Q1 2027 report, including a new Street-high $300 target from HSBC. The current market price is hovering around $200, so there's still plenty of upside available in MRVL shares. 

Applied Optoelectronics Inc.

Tiny fiber-optic networking company Applied Optoelectronics (NASDAQ:AAOI) has been one of 2026's big winners, soaring more than 350% YTD and boosting its market cap over $12 billion.

The company posted a larger-than-expected loss in its Q1 2026 report last month, but also recorded record revenue of over $150 million, its fourth straight quarter of positive revenue growth (and third of at least 10% sequential growth). Management expects another big revenue gain in Q2, guiding a range of $180 to $198 million.

Right now, AAOI shares could be offering a rare chance to buy at a discount. The stock has pulled back to the 50-day moving average and trades around $160, which is nearly 30% below the $220 price target Rosenblatt set following the Q1 earnings report. The RSI has also pulled back to its lowest point since April, which previously served as an excellent entry point.

Analog Devices Inc.

Analog Devices (NASDAQ:ADI) might be the safest investment among the five companies listed here, thanks to its dual-pronged revenue stream.

Fiscal Q2 2026 was one of the best in the company's history, thanks to record sales of $3.62 billion and rapidly accelerating growth in two segments. The Communications segment, which supplies integrated circuits to data centers, grew 63% YoY, and the Industrial segment rebounded sharply, growing 38% YoY.

The Industrial rebound gives Analog Devices a separate growth engine should data center capex slow, and management also raised its dividend for the 22nd consecutive year.

ADI shares are "only" up 50% YTD, but there could be plenty of upside ahead as the stock catches up to some of its parabolic peers. ADI trades at 33 times forward earnings, which is below the industry average of 37, and now the stock has technical momentum with the RSI sticking above the bullish threshold of 50.
