Friday's US Stock Movers: AMAT, NU, SNDK Lead as Tech and Financial Sectors Diverge

Friday's US Stock Movers: AMAT, NU, SNDK Lead; Tech and Financial Sectors Show Clear Divergence

In Friday's US stock trading, several stocks experienced significant fluctuations, with semiconductor equipment giant Applied Materials (AMAT), Brazilian digital bank Nu Holdings (NU), and flash memory chip maker SanDisk (SNDK) becoming market focal points. Overall, the tech sector showed internal divergence, while fintech and memory chip areas were driven by both news flow and capital flows.

AMAT: Semiconductor Equipment Demand Recovery Expectations Boost Stock

Applied Materials (AMAT) led gains during Friday's session, primarily driven by optimism over a recovery in semiconductor equipment spending. Reports indicate that several wafer foundries have recently raised their capital expenditure guidance, coupled with sustained demand for advanced process equipment from AI chips. As a global leader in deposition and etching equipment, AMAT is seen by investors as a direct beneficiary. Additionally, analysts point out that memory chip makers' expansion plans may accelerate in the second half, further supporting AMAT's order visibility. However, some traders caution that the stock has already risen significantly recently, posing a short-term technical correction risk.

NU: Digital Bank User Growth Strong, but Valuation Debate Persists

Brazilian digital bank Nu Holdings (NU) saw its stock rise on Friday, following the company's latest operational data showing continued expansion of its customer base, particularly with increased penetration in Mexico and Colombia. According to company disclosures, monthly active users surpassed the 100 million mark, and average revenue per user is trending upward. However, market disagreement over NU's valuation remains: bulls argue that its high growth justifies the current P/E ratio, while bears worry that rising credit costs in Latin America could erode profits. Friday's rise reflects more of a short-term sentiment repair than a fundamental shift.

SNDK: Flash Memory Price Hike Cycle Begins, Memory Chip Sector Rallies

SanDisk (SNDK) performed strongly on Friday, lifting the entire memory chip sector. According to supply chain sources, NAND flash contract prices, after several quarters of decline, are showing signs of stabilizing and rebounding, with some manufacturers already starting to raise quotes for the next quarter. As a standalone flash memory solution provider, SNDK is most sensitive to price elasticity, hence its stock reacted most sharply. Additionally, growing demand for high-capacity storage from AI servers provides new incremental growth for the industry. However, investors should note that the memory industry is highly cyclical, and whether current price increases can persist depends on the strength of end-demand recovery.

Other Movers: Market Sentiment Cautiously Optimistic

Besides the three stocks mentioned above, several other stocks saw significant moves on Friday due to earnings or news flow. For example, a US regional bank fell due to quarterly provisions exceeding expectations, while a biotech company surged on positive results from a new drug clinical trial. Overall, the market is awaiting next week's key inflation data and Federal Reserve officials' speeches, with capital operations cautious but no systemic selling.

Outlook: Focus on Rate Path and Tech Earnings Validation

From the market structure, funds are rotating from defensive sectors (such as utilities and consumer staples) into growth sectors, but the rotation is fast, indicating investors' confidence in a soft landing remains shaky. For stocks like AMAT, NU, and SNDK, future trends will depend more on fundamental catalysts in their respective industries: semiconductor equipment should watch capital expenditure guidance from major players like TSMC and Samsung; Nu Holdings should monitor the impact of Brazil's central bank rate cuts on credit demand; and SanDisk needs to track monthly changes in memory contract prices. Overall, Friday's gains are more of a combination of oversold bounces and expectation corrections, rather than the start of a trend reversal.
