Micron’s shares closed at $690.00 on November 6, up 141.76% from $285.41 at the end of 2025, and AMD’s closed at $449.04, up 109.68% from $214.16, according to Nasdaq.com closing prices. Over the same span, the simple average change for Amazon, Microsoft, Meta and Alphabet was +1.4%, by our arithmetic.
A StockMKTNewz post on X on November 7 listed “how the largest stocks have performed so far in 2026”. Our own calculation from Nasdaq.com closes gives the same percentages for the ten technology names it lists. Oracle, which the post does not list, fell 40.43%, leaving 182.2 percentage points between Micron and Oracle, by our arithmetic.
Business Pill · Concentration
A short Business Engineer explainer on concentration: when a few big pieces make up most of a total. It teaches the general idea only and does not discuss these companies.
The key insight: From the 31 December 2025 close to the 6 November 2026 close, Micron rose 141.76% and AMD 109.68%, while the simple average of Amazon, Microsoft, Meta and Alphabet was +1.4% and Oracle fell 40.43%, by our arithmetic from Nasdaq.com closes. That leaves 182.2 percentage points between Micron and Oracle.
Here are six chip makers from the 31 December 2025 close to the 6 November 2026 close, by our arithmetic from Nasdaq.com closes.

StockMKTNewz posted at 20:05 UTC on 7 November a list of “how the largest stocks have performed so far in 2026”, including Micron at +141.76%, AMD at +109.68%, Nvidia at +0.08% and Alphabet at -9.02%. Our own calculation from Nasdaq.com closes for 31 December 2025 and 6 November 2026 gives the same percentages for the ten technology names on the list.
The Hyperscalers
The four hyperscalers in our chart, over the same dates: Amazon +12.34% (from $230.82 to $259.30), Microsoft +9.72% (from $483.62 to $530.61), Meta −7.57% (from $660.09 to $610.15) and Alphabet’s Class A shares −9.02% (from $313.00 to $284.78), by our arithmetic from Nasdaq.com closes. Their simple average is +1.4%.
Oracle fell 40.43%, from $194.91 to $116.10. It is the weakest of the thirteen names in our chart, which also includes Apple at +25.94% and Tesla at −20.35%.
Memory’s Year, Week by Week
Micron’s gain for the year includes a recent fall. From the 29 October close to the 6 November close, Micron fell 26.1%, our earlier piece found, while Counterpoint Research said memory prices were still rising.
Our earlier pieces also track the wider memory and lithography market. Winbond’s October revenue was NT$29.361 billion, up 256.96% from a year earlier, and its chairman told reporters they hope memory prices have peaked. Samsung and SK Hynix are each putting 10 trillion to 20 trillion won into ASML lithography tools, Chosun Biz reported.
The Structural Read
As we read the closing prices, the biggest 2026 gains among these thirteen names went to Micron and AMD, while Nvidia ended the period roughly where it started, at +0.08%.
As we read the hyperscaler figures, Amazon, Microsoft, Meta and Alphabet averaged +1.4% for the year by our arithmetic, with Meta and Alphabet below their year-end 2025 closes.
As we read our earlier coverage, Micron’s year includes a 26.1% fall from 29 October to 6 November, and Intel is up 52.52% for the year despite a 53.2% drop since 30 September.

Three Implications
FOR CHIP MAKERS Micron closed at $690.00 and AMD at $449.04 on 6 November, against $285.41 and $214.16 at the end of 2025, by Nasdaq.com closes.
FOR THE HYPERSCALERSAmazon rose 12.34% and Microsoft 9.72%, while Meta fell 7.57% and Alphabet 9.02%, by our arithmetic from Nasdaq.com closes.
FOR THE NUMBERS TO WATCH Oracle closed at $116.10 on 6 November, 40.43% below its $194.91 close at the end of 2025, by our arithmetic.
The essay says “The within-layer split is what makes silicon strategically interesting again” and lists the HBM oligopoly of SK Hynix, Samsung and Micron in its foundries and packaging layer.
As we read it, the 2026 closing prices show a split inside the chip layer too, from Micron at +141.76% to Broadcom at −15.14%; the essay does not discuss share prices.
What Is Not Established
These are share-price changes only, not total returns: they leave out dividends. The end date is the November 6 close, the last trading day before this piece. The closing prices do not give reasons for any move, and the group averages are simple, unweighted averages that we computed; they are not index returns. The post’s percentages match ours to two decimals, and we did not check its non-technology names.
This Week In The AI Supercycle
The Great Convergence of Capital, Power, and Geopolitics
This week’s issue: for two years the AI build-out was priced as a supply story, and last week as a credit story. This week it was priced as a permission story, and the answer arrived as a cost, not a ban.
From the 31 December 2025 close to the 6 November 2026 close, Micron rose 141.76% and AMD 109.68%, while Nvidia was flat at +0.08%, Alphabet fell 9.02% and Oracle 40.43%, by our arithmetic from Nasdaq.com closes. The simple average of Amazon, Microsoft, Meta and Alphabet was +1.4%, and the six chip makers in our chart averaged +52.1%.
A note on sourcing. Share prices are Nasdaq.com historical closing prices (close field) for 31 December 2025 and 6 November 2026; TSMC is its US-listed ADR. The StockMKTNewz post is cited for its list, which our calculation matches. Memory, Winbond and EUV figures are from our earlier pieces, which cite their sources. Percentage changes, differences and simple averages are our arithmetic.
