INTC, SNDK, LWLG Stocks Hit 52-Week Highs Last Week: What’s Driving The Rally?

• Intel rose after multiple analyst upgrades, with brokerages highlighting stronger demand for server CPUs.
• SanDisk gained after confirmation that it will join the Nasdaq-100 Index on April 20, adding a fresh catalyst alongside firm memory-sector sentiment.
• Lightwave Logic benefited from the growing demand for optical interconnect technology.

Shares of Intel (INTC), SanDisk (SNDK) and Lightwave Logic (LWLG) climbed to fresh 52-week highs last week as strong memory pricing, photonics momentum, and renewed confidence in AI infrastructure demand drove investors back into semiconductor supply-chain firms.

The rally coincided with broader strength across tech stocks, with the Tech Select Sector SPDR Fund (XLK) posting eight straight sessions of gains, its best weekly run in nearly a year.

Intel Rises On AI Strategy Validation

INTC gained after multiple brokerages lifted price targets and highlighted strong demand for server processors and heterogeneous AI computing.

Jefferies recently raised the firm’s price target to $60 from $45, implying a 4% downside from current levels. The brokerage cited “healthier” server central processing unit demand and favorable pricing conditions, while noting that AI stocks have started to rally with “plenty of room to run with heavily discounted valuations and earnings upside for several names.”

Intel has also drawn investor attention through its partnership with SambaNova Systems on inference architectures and its participation in the Terafab initiative alongside SpaceX, xAI, and Tesla.

Meanwhile, Benchmark said Intel’s recent deals address “both of the key debates in the stock at once,” referring to the durability of CPUs in AI infrastructure and the commercial credibility of its 18A manufacturing process. Melius Research also lifted its price target to $75 from $58, suggesting a 20% upside, while Cantor Fitzgerald raised its target to $60 from $45, saying a shift back toward a semiconductor “RISK-ON position” could arrive “NOW or SOON.”

SanDisk Gains On AI Flash Storage Demand

SNDK rallied after confirmation that the company will replace Atlassian Corporation in the Nasdaq-100 Index before the market opens on April 20.

Sentiment was further boosted with several analyst upgrades after Jefferies raised its price target to $1,000 from $700, implying a 17% upside from current levels. The brokerage cited “relentless AI demand” and expectations for further NAND price increases. Bernstein also raised its target further to $1,250 from $1,000, implying a 47% upside, noting memory prices continue to “surprise to the upside” with NAND showing the strongest acceleration.

Separately, SanDisk has reportedly begun building supply-chain partnerships for High Bandwidth Flash (HBF) architecture, a stacked-NAND technology that increases both storage capacity and bandwidth for AI workloads.

Lightwave Logic Lifted By Photonics Sector Tailwinds

Momentum also extended to shares of optical interconnect suppliers such as LWLG, underscoring demand for the networking layer required to scale hyperscale AI infrastructure.

The company’s electro-optic polymer modulator platform became available in March as part of the GlobalFoundries silicon photonics ecosystem via the GDSFactory process design kit, enabling customers to integrate high-speed modulators directly into photonic integrated circuit designs.

Lightwave Logic also said in February that a Fortune Global 500 customer progressed to a more advanced stage of its commercial evaluation process after testing its Perkinamine technology, which is being developed to support ultra-high-speed connections used in hyperscale AI data centers.

Broader sector tailwinds strengthened sentiment last month following Nvidia's $2 billion investment in optical-component supplier Lumentum.
