ON Semiconductor Stock Rises. The Chip Maker’s Worst Days Are Behind It, CEO Says

ON Semiconductor rose 6% Wednesday after the chip maker’s CEO stressed that things would only improve following a mixed first-quarter print.

ON Semiconductor jumped 11% Tuesday after CEO Hassane El-Khoury appeared at the Bank of America Global Technology Conference and repeatedly emphasized that On Semi was “expecting growth.”

“We feel good about the second half [of the fiscal year],” the chief executive said. “The second half is the first step of, did we hit the bottom, and are we gonna see recovery from there?”

It was welcome news after ON Semiconductor’s fiscal first-quarter results, released last month. While adjusted earnings topped expectations, analysts picked up on indicators of weakening customer demand, causing shares to tumble. Total revenue declined 22% in the quarter ended April 4 and decreased across all three business segments.

Dollar General Lifts Annual Targets as Shoppers Flock Amid Tariff Fears

Dollar General raised its annual targets after beating estimates for quarterly profit and same-store sales and said more consumers across income groups came in to shop at its stores amid tariff-related uncertainty and still-high inflation.

The forecast lift took the company's shares up 16% on Tuesday and came in sharp contrast to other retailers cutting financial targets and sounding caution on consumer spending due to President Donald Trump's sweeping tariff policies.

Mizuho Raises Micron Stock Price Target to $130 Ahead of Earnings

Mizuho analysts raised their price target for Micron Technology to $130 from $124 on June 4. They also maintained an ‘Outperform’ rating on the shares. This adjustment comes ahead of Micron’s Q3 FY2025 earnings report scheduled for June 25.

The price target increase stems from Mizuho’s analysis of Micron’s positioning in the High Bandwidth Memory (HBM) market. The analysts project that the HBM industry revenue will expand at a 55% compound annual growth rate (CAGR) from 2024 to 2027. They noted that a key driver of this growth is the adoption of HBM4 and HBM4e technologies.

Mizuho expects Micron’s HBM revenue to outpace the broader market, growing at a 90% CAGR over the same timeframe. The firm anticipates that Micron will capture increased market share, growing from approximately 10% in 2024 to 20-25% by 2025-2026. This expansion will enhance the company’s DRAM revenue while improving top-line performance and gross margins.

The analysts also highlighted Micron’s strong NAND technology roadmap, noting the company’s continued advancement toward more sophisticated 3XXL nodes. According to their assessment, these technological advancements and market share gains position Micron favorably for the upcoming earnings period and beyond.

NUE Stock Jumps on Increased Steel Tariffs

Nucor experienced a significant stock movement this week, remaining stable with no percentage change noted. This movement is in line with the recent announcement of increased steel tariffs, which are influential for domestic steel producers like Nucor.

In a strategic move to capitalize on favorable market conditions, Nucor has invested over $10 billion in various projects over the past five years to augment its earnings. Among these initiatives, two major projects are anticipated to commence operations later this year: a greenfield sheet mill in West Virginia, slated for completion by year-end.

The financial metrics for Nucor provide a mixed picture. Despite generating over $8 billion in free cash flow in 2022 and an additional $5 billion in 2023, the first quarter of this year saw a decline to negative $495 million. Nevertheless, the tariff adjustments are likely to bolster steel prices, potentially enhancing Nucor's future business performance.
