AXT, Inc. has the financial strength to support aggressive indium phosphide (InP) capacity expansion, positioning the company to capitalize on strong AI data-center demand. AXT ended the second quarter with $748.8 million in cash, cash equivalents and investments, up $625.6 million sequentially, primarily following its April secondary offering, which generated approximately $632 million before expenses. This strengthened liquidity provides financial flexibility to expand its manufacturing footprint. The timing is favorable because InP demand continues to exceed supply. AXT has committed to doubling InP capacity in 2026 and is ahead of schedule while planning another expansion in 2027. Its InP backlog has surpassed $100 million, providing visibility into future demand. Customer commitments further strengthen the outlook, with long-term agreements including Casela, Coherent, and Lumentum, the latter reserving InP capacity through 2031. AXT's second-quarter revenues reached a record $47.6 million, while GAAP gross margin climbed to 44.9%. The Zacks Consensus Estimate projects 2026 and 2027 revenue growth of 146.4% and 108.4%, respectively. However, competitive pressure is rising as Coherent and Lumentum expand their own InP production, potentially reducing reliance on AXT. AXT shares have skyrocketed 325.4% year to date, and the stock carries a Zacks Rank #1 (Strong Buy).
AMD CEO Lisa Su Says Chip Demand Outruns Supply, Plans Capacity Years Ahead
Advanced Micro Devices CEO Lisa Su said chip demand remains ahead of supply and expects it to stay very high for the next several years, speaking to reporters in Taipei on October 6. Su said AMD has increased supply through 2026 and plans a much bigger jump in 2027, with capacity now planned three to five years ahead. Her Asia trip included meetings with Foxconn and TSMC, followed by talks with memory makers in South Korea, as AI chips depend on large amounts of memory that constrain how many AMD can ship. Stifel raised its AMD target to $700 on October 5, arguing AI buildouts are limited by chip supply. AMD's forward non-GAAP P/E of 83.38x and forward price-to-sales ratio of 20.25x both sit at more than double their 5-year averages, while analysts expect EPS to rise about 82% in 2026, 107% in 2027 and 45% in 2028.
Micron Technology Taoyuan Workers Vote to Authorize Strike Over Bonus Dispute
Workers at Micron Technology's Taoyuan facility in Taiwan have voted to authorize a strike after bonus negotiations failed. The authorization covers staff at a key memory manufacturing plant that supports Micron's global supply chain for memory and storage products, with labor representatives framing the dispute around year-end compensation and bonus terms tied to recent corporate performance metrics. The vote puts a critical production hub at higher operational risk just as Micron runs very high capex and leans on tight DRAM and NAND supply as a profit driver, while rivals Samsung and SK Hynix contest AI memory share. Micron designs and manufactures memory and storage products across the United States, Taiwan, Japan, Mainland China, Hong Kong and Europe, so any disruption in Taiwan affects a production network serving data centers, consumer devices and AI hardware customers worldwide. Analysts have already flagged high capital intensity and cyclicality as major risks, and the dispute adds a people and supply-chain layer to that same concern.
MU · Supply · Negative Taoyuan workers authorize a strike at a key memory plant, raising operational risk to Micron's DRAM/NAND production and supply chain.
Jacob Funds Adds Rambus Stake on Data Center Memory Shift
Jacob Funds disclosed a new position in Rambus Inc. in its third-quarter 2026 investor letter, citing the memory chip maker's exposure to data center infrastructure trends. The Jacob Internet Fund added Rambus as its sole new holding in the quarter, with the firm arguing the market underestimates the rollout of next-generation MRDIMM server memory, which doubles data transfer speeds without costly server redesigns. Jacob Funds said the shift toward memory pooling should lift the dollar value of Rambus components inside every AI server, driving higher average selling prices and wider margins in its product revenue category. Rambus closed at $108.47 on October 08, 2026, with an $11.76 billion market capitalization, an 18.04% year-to-date gain, a 52-week range of $77.89 to $174.10, and $756.33 million in trailing twelve-month revenue. Fifty hedge fund portfolios held the stock at the end of the second quarter, up from 35 in the previous quarter.

Samsung Posts Record $80.2 Billion Quarter as TSMC Revenue Jumps 50%
Samsung Electronics reported the most profitable quarter ever by any company at $80.2 billion, while Taiwan Semiconductor Manufacturing Company posted record third-quarter revenue of $46.7 billion, up 50% year over year. Samsung, the world's largest memory manufacturer, counts Qualcomm, Alphabet, Tesla, Advanced Micro Devices and Amazon among its main customers. TSMC, the world's largest manufacturer of AI chips, produces over 60% of all global contract chips and over 90% of advanced chips, with NVIDIA, AMD, Qualcomm, Intel, Apple and Broadcom among its customers. Earlier this week, SpaceX announced it will raise $40 billion in debt to buy NVIDIA chips as it scales its AI compute, with a payback period well under one year thanks to deals with Google and Anthropic. The results and the SpaceX debt raise suggest record capital expenditure on AI infrastructure will continue.
Bank of America Starts Penguin Solutions at Buy With $100 Price Target
Bank of America initiated coverage of Penguin Solutions with a Buy rating and a $100 price target, sending shares up 3.8% in premarket trading on Friday. Analyst Wamsi Mohan wrote that Penguin sells memory and full-stack AI infrastructure to business, government and neocloud customers, and called the company a key beneficiary in the age of agentic AI. AI-driven businesses already comprise 78% of sales and grew 141% year over year last quarter, Mohan noted. He sees upside to his above-Street estimates, projecting fiscal 2028 revenue of $2.87bn and EPS of $5.43 versus the Street's $2.66bn and $5.04, driven by a sustained memory cycle through 2028, growing traction from agentic AI demand, improving margins and Penguin's ability to lower the time to first token in inference applications. Mohan added that Penguin's CXL products and MemoryAI KV cache servers address rising memory constraints directly, and that a Tier-1 financial institution has already expanded its usage.
Samsung Electronics released preliminary third-quarter 2026 earnings guidance on October 8, projecting consolidated operating profit of approximately 107.4 trillion Korean won, up about 782.5% year on year, with consolidated sales of roughly 195 trillion Korean won, up about 126.6%. Earlier, Micron Technology reported fourth-quarter fiscal 2026 revenue of 54.23 billion US dollars, up about 379% year on year, and guided next-quarter revenue to approximately 61.5 billion dollars. Guolian Minsheng Securities stressed that the memory industry is entering a supercycle, with AI server demand continuing to drive upgrades in HBM, DRAM, and enterprise SSD configurations, while supply-side constraints on advanced process capacity and long-term agreement lock-in mechanisms make the upward price trend clear. Leading manufacturers such as Micron have already locked in more than 35% of revenue through 2030 via long-term agreements and plan to boost shareholder returns. As a result, as of 14:11 on October 9, 2026, the STAR 50 ETF Ping An, ticker 589150, saw its underlying index, the SSE STAR 50 Index, ticker 000688, rise 0.23%, with constituents Amlogic up 5.84%, Transsion Holdings up 5.42%, Times Electric up 4.35%, Skyverse up 4.23%, and SJ Semiconductor up 4.05%.
