Biggest Movers This Quarter
The largest swings this quarter, up or down
This list tracks the largest rank swings of the quarter in either direction, and roughly half of it is falling rather than rising — a sharp decline is exactly as newsworthy as a sharp rise, and this list refuses to only cover good news. Each entry states plainly whether it moved up or down and why, rather than burying a decline in vague language. Some of these swings will hold for years; others are likely to reverse by the next update, and the note on each entry says which looks more probable.

Rank 01Editor’s pick
DeepSeek
DeepSeek · open-weight models · 2023
An open-weight model that matches GPT-4-class reasoning on many benchmarks at a fraction of the API cost, which is why it forced every major lab to cut prices within weeks of release.

Humane AI Pin
Humane · wearable AI device, launched April 2024 — assets acquired by HP, 2025
A screenless, voice-and-projection wearable meant to reduce phone dependence, the AI Pin shipped to overwhelmingly negative reviews citing overheating, sluggish response times and a subscription fee on top of an already high device price; Humane sold its core assets to HP roughly a year after launch.

Northvolt
Swedish EV battery maker · filed for bankruptcy, November 2024
Once positioned as Europe’s best hope for a homegrown battery-manufacturing champion and backed by billions from investors including Volkswagen and Goldman Sachs, Northvolt filed for Chapter 11 bankruptcy protection after production delays and quality problems it was never able to fully resolve.

Consumer genomics company · filed for bankruptcy, March 2025

Novo Nordisk
Danish pharmaceutical company · semaglutide (Ozempic, Wegovy)
Novo Nordisk’s GLP-1 drugs have become genuinely difficult to overstate as a business story — demand has repeatedly outstripped manufacturing capacity, briefly making the company Europe’s most valuable by market cap, while health systems worldwide scramble to work out how to pay for a drug class this broadly effective.

Alphabet subsidiary · autonomous robotaxi service

Boeing
American aerospace manufacturer · ongoing safety and quality scrutiny
The January 2024 Alaska Airlines door-plug blowout reopened scrutiny of Boeing’s manufacturing quality control that the company had never fully put to rest after the 737 MAX crashes, and leadership changes, regulatory production caps and a fresh round of whistle-blower allegations have kept the story in the headlines through this year.

Intuitive Machines
Houston, Texas · first US commercial Moon landing, February 2024

Apple Vision Pro
Apple · mixed-reality headset, launched February 2024
Apple’s first major new product category in nearly a decade drew enormous launch-week attention and a $3,499 price tag to match, but reported sales cooled sharply after the initial wave of early adopters, with several retail reports of underwhelming reorder demand through the device’s first full year.

Rivian R2
Rivian · mid-size electric SUV, unveiled March 2024

Intel
Semiconductors · Founded 1968
“Intel Inside” did something almost no ingredient brand had done before — made a component invisible to the end user into a purchase driver in its own right. That halo has faded as the chip itself lost its unquestioned performance lead.

How this list is scored
Four criteria, weighted before the first entry
Movement is tracked as signed rank change on each entry’s home category list; a large negative number is treated with exactly the same editorial weight as a large positive one, not downplayed.
- Magnitude of movement 30%
- Absolute size of the rank swing, up or down, over the comparison window.
- Clarity of cause 25%
- How well the underlying reason for the move can be documented and sourced.
- Real-world consequence 25%
- Whether the move reflects a change with genuine downstream impact, not just news-cycle noise.
- Durability of the new position 20%
- Likelihood the move holds rather than reverting by the next update.
Questions
About this ranking
Why include companies that are failing, not just succeeding?
A collapse is exactly as significant a move as a breakout success, and this list would be a worse editorial product if it only tracked good news. Northvolt’s bankruptcy is as much a "biggest mover" as BYD’s growth.
How is "likelihood the new position holds" judged?
Against precedent. A bankruptcy filing is treated as durable; a single bad product cycle or a weather-driven disruption is treated as more likely to reverse.
Do the same entries reappear quarter to quarter?
Rarely by design. An entry that has already made its big move typically drops off in favour of the next quarter’s sharpest swings, up or down.
How often does this list update?
Weekly. "This quarter" in the title refers to the comparison window each rank change is measured against, not the update frequency.
