The AI boom has turned High-bandwidth memory (HBM) into a key bottleneck for chipmakers. Thanks to the ‘bottleneck’, the top 3 HBM suppliers’ stock prices have soared to new highs, since April 2026. (see below) 01 Apr 2026 to 18 Aug 2026 $Micron Technology(MU)$ has risen by about +155.75%. SK Hynix (Korea) have risen by +67.22%. Samsung (Korea) have risen by +30.5%. Given above backdrop, the latest twist in $NVIDIA(NVDA)$’s roadmap makes it especially important for HBM suppliers. The AI buildout (set in motion) is creating an unusual problem for semiconductor investors - demand is arriving faster than the supply chain can deliver the most advanced components. Booming demand for AI chips is creating a tricky

On August 17, Micron jumped 4.1% and closed back above $1,000 after several strong sessions. But the rally was quickly tested at Tuesday’s open, with shares falling more than 4% as chip stocks pulled back. Congrats to @wywy , who made $122,809 by holding Micron shares. Congrats to @Ping39 , who made $42,518 by trading Micron calls. SanDisk lit the match The latest rally started with SanDisk.At its August 13 Investor Day, SanDisk said it expects revenue to grow at a mid-to-high-teens CAGR from FY2028 through FY2030, while long-term gross margin could stay around 80%. The stock surged 13.7% that day, and Micron quickly followed, gaining 4.23% on August

I would pick A. Micron for the next three years. Nvidia remains the strongest AI leader, but expectations and valuation are already extremely high. Micron offers a different way to capture the AI boom, particularly through HBM and high-end memory. AI workloads are becoming increasingly memory-intensive, creating potentially structural demand for faster, higher-capacity memory. The biggest attraction is the possibility that AI demand keeps memory supply tight for longer, allowing Micron to sustain unusually strong pricing and margins. If that happens, earnings growth could significantly outpace the broader market. Berkshire is the safer choice, with diversified businesses, strong cash flow and a huge liquidity cushion. It would probably be my pick if capital preservation were the priority.

For me, I’d pick Micron for the next three years — but with a much higher risk tolerance. Berkshire is the safer compounder, while Nvidia remains the core AI leader. But Micron has an interesting middle ground: it’s benefiting from the same AI spending boom, yet the market is only now starting to treat memory as strategic infrastructure rather than a commodity. The key is HBM. If AI demand keeps growing and memory supply remains tight, Micron’s earnings could surprise on the upside. That gives MU more potential upside than Berkshire, although the volatility will be much higher. So my ranking would be: MU for upside, NVDA for AI leadership, BRK for stability. The real question isn’t whether Micron can stay above $1 trillion — it’s whether AI has permanently changed the memory cycle. If the

If I had to choose, I would go with C. MU. SNDK’s long-term targets are impressive, but after a 13.7% one-day surge and a massive run this year, I don’t want to chase it. $Micron Technology(MU)$ gives me broader exposure to HBM, DRAM and NAND, allowing me to benefit from both AI memory demand and the broader storage cycle. The reactions to AMAT, COHR and Cisco also show that strong earnings are no longer enough when expectations are already high. For me, the key is whether AI demand can translate into sustainable earnings and cash flow. I believe MU still offers a better balance of growth, valuation and upside. So I remain bullish on storage, but I would accumulate MU on pullbacks rather than chase SNDK after its sharp rally. If MU and

A few years ago, putting $Micron Technology(MU)$ and $Berkshire Hathaway(BRK.A)$ in the same market-cap conversation would have sounded almost absurd. Micron was known as a highly cyclical memory-chip manufacturer, while Berkshire became one of the world’s largest conglomerates through insurance, railroads, energy, industrial businesses and decades of capital allocation. AI has almost erased that valuation gap. Micron crossed US$1 trillion in market value for the first time in May, then briefly reached around US$1.4 trillion in June, overtaking Meta and trading above Berkshire at the time. After a volatile summer, Micron closed Aug. 12 at US$911.29, valuing the company at ro

Micron Technology’s ascension to the $1 trillion market cap threshold marks a fundamental paradigm shift in how global financial markets value memory chipmakers. Traditionally regarded as commoditized, highly cyclical "pig-iron" vendors whose fortunes rose and fell with PC and smartphone refresh cycles, memory producers have been re-rated as critical bottleneck providers for the generative AI revolution. The rally in $Micron Technology(MU)$ Micron (MU), alongside peers SK Hynix and Samsung, is not merely a temporary cyclical rebound. Instead, it represents a structural multi-year expansion driven by High-Bandwidth Memory (HBM3e/HBM4) demand and an severe supply squeeze in conventional DRAM. 1. Memory Sector Dynamics: Rebound vs. Structural Reversal

Stop calling it a bounce. A bounce is what happens when nothing changed. What happened Thursday is different. Four separate entities, Samsung, Microsoft, Amazon, and Apple, each independently confirmed within 24 hours that the AI memory shortage is real, worsening, and extending further than the market had priced. When the buy-side was selling memory stocks on CXMT IPO fears and AI capex peak anxiety, the sell-side of that trade just had its thesis demolished by the four largest technology companies on Earth. Here is the full picture. Samsung reported its highest-ever quarterly revenue with operating profit of 89.5 trillion won, ahead of expectations. More importantly, it warned that memory supply constraints may persist into 2028 and signed multi-year supply agreements with major data cen

The memory trade has been one of the strongest semiconductor themes of 2026. AI data centres have driven extraordinary demand for memory and storage, while limited supply has pushed NAND and DRAM prices sharply higher. That combination helped send memory stocks to some of their strongest gains in years. This week, though, the trade showed a fresh sign of stress. $SanDisk Corp.(SNDK)$ fell 6.8% on Thursday after investors reacted negatively to its outlook, while $Western Digital(WDC)$ dropped 13%. SK Hynix lost around 5%. $Micron Technology(MU)$ initially fell more than 7% before recovering most of the decline and closi

$Micron Technology(MU)$   Micron Technology (NASDAQ: MU) has been one of the hottest performers on the stock market over the past year, but its shares have witnessed a substantial pullback after reaching a 52-week high on June 25. Specifically, Micron stock is down nearly 28% from its 52-week high. This steep slide in the memory specialist's shares is quite surprising when we consider that it reported incredible results toward the end of June, along with impressive guidance. Clearly, external factors are impacting this high-growth company. So, even if Chinese memory manufacturers bring more supply to the market, undersupply is likely to persist. After all, shipments of personal computers and smartphones are takin

$Apple(AAPL)$ fell 7.35 per cent on Friday, the only mega-cap to drop hard. The same day, $Amazon.com(AMZN)$ rose 15.32 per cent and $Alphabet(GOOG)$ 6.88 per cent. I left a question hanging last time. Tim Cook's line — memory is tight, it will hit next quarter — went into Apple's guidance, and it went into somebody's revenue too. Friday answered. It answered half. Apple's column got copied down; the column belonging to whoever collects the money got rubbed out. $Micron Technology(MU)$ -5.90%, $SanDisk Cor

These four earnings reports did not prove that the storage cycle is ending. If anything, they confirmed the opposite: AI data-center orders remain strong, storage prices are still rising, and supply remains tight. What has changed is the market’s scoring system. Previously, revenue growth and record profits were enough to push a stock higher. Now, even the strongest results in a company’s history can trigger a selloff if they fail to beat already-extreme consensus expectations. That is also how I view the upcoming earnings report from $SanDisk Corp.(SNDK)$ The results will probably be very strong. The problem is that “very strong” may no longer be enough.

After several brutal sessions, global technology stocks finally staged a powerful rebound. The Nasdaq rose 2.8%, while Microsoft’s post-earnings surge helped lift AI chips, cloud stocks and data-center names across the board. The move became even more dramatic in Asia. South Korea’s KOSPI jumped sharply, with Samsung Electronics and SK hynix surging as investors rushed back into semiconductor names. Taiwan’s market also rebounded strongly, led by TSMC. At first glance, this looks like a classic V-shaped reversal. But the more important question is: Has the correction really ended, or is the market only beginning a longer U-shaped repair process? Why did the rebound happen so quickly? The first reason is earnings. Microsoft showed that AI spending can already translate into cloud revenue, p

Micron's $1T "reclaim" is really a rematch of the same argument the market had in May — and the CXMT wildcard cuts both ways Worth remembering the context: Micron first crossed $1T back in May off UBS's 204% price-target hike to $1,625, built on a structural thesis — long-term agreements are turning DRAM from a spot-priced commodity into something closer to contracted, growth-multiple earnings. Tuesday's move (+4.92% MU, +9.01% SK Hynix, +5.76% SanDisk, SOXL +6.89%) is that same thesis getting a fresh catalyst: management extending the tightness call past 2027, UBS following with a through-cycle profitability reset. Here's the part that actually resolves your "who sets the price" question: SemiAnalysis's own supply-side model — the one most often cited to justify CXMT as the bear case — st

$Microsoft(MSFT)$ up 7.70% after hours. $Meta Platforms, Inc.(META)$, down 7.10%. Same evening, same underlying fact — both companies are spending unholy amounts of money on AI — and fifteen points of daylight between them. Read those two numbers alone and you'd conclude the market turned on AI capex. It didn't. It did something more annoying: it started sorting. Start with who flipped the switch. The July FOMC didn't move rates and didn't change a word of the guidance. Warsh spoke, and within thirty minutes the ten worst names on the tape were almost all AI. The S&P 500 closed down 1.52% at 7,316.15, the Nasdaq Composite down 1.74%,

$Apple(AAPL)$ beat on revenue for its fiscal third quarter and fell 5.74 per cent after hours. Once the same call had wrapped up, $SanDisk Corp.(SNDK)$ rose 4.61 per cent in extended hours and $SK hynix(SKHY)$ 3.76 per cent. Between the two sits a single remark from Tim Cook: memory supply is tight, it will hit next quarter, and the company is stockpiling hard to get ahead of significant supply constraints. On Apple's books that sentence is a cost. On a memory maker's books it is revenue. One fact, two income statements, opposite signs. Before we put the whole 5.74 per cent on that one line: the same results missed
