The memory selloff is not a RAM sale
Micron, SanDisk and SK Hynix fell double digits on 5 November and Reddit read it as cheap RAM. A share price is not a contract price, and contracts rose.

On Thursday 5 November the Philadelphia Semiconductor Index fell 12.2% and the Nasdaq Composite closed 5.5% lower, more than 10% below its recent peak, as CNBC reported the next morning from Asia. That night the top post on r/LocalLLaMA was titled "Maybe we'll get cheap RAM for Christmas after all!", carried its own percentage table, and drew 1,701 points and 363 comments. The inference is tidy: memory makers crashed, so memory gets cheap. It is the one step in the chain that the same week's reporting does not support.
What the tape did, and who measured it
Invezz, publishing through TradingView at 11:26 ET on 5 November, had Micron down nearly 16%, SK Hynix 13% and SanDisk 20%. Those are mid-session numbers, stamped and attributed. The session did not stop there: CNBC's Friday report from Asia put SK Hynix down another 10.44%, Samsung 6.35%, SoftBank 10.83%, TSMC 4.69% and Kioxia 8.72%.
Two explanations travelled with it. One was political: Democratic gains in the US midterms raised the prospect of tighter scrutiny of data-centre construction and power use. The other was older: memory stocks had already been hit in mid-October on China's CXMT and a South Korean column warning of a 2029 glut, when SK Hynix fell 26% in five days, Samsung 22% and Micron 11%. Goldman Sachs' Timothy Moe described the mechanism to CNBC: "The market's tendency is always to shoot first and ask questions later."
Two tables, and only one of them is sourced

They disagree on every name they share, by two to three points, and neither is wrong in the way a reader assumes. A quote taken at 11:26 ET is not a close; a close is not a week. The post's table carries no timestamp and no source, so it cannot settle a two-point gap. Print both, average neither. Both describe the same object: the price of a share in a company that sells memory, not the price of memory.
The number that did move is the contract
DRAM does not trade on a screen the way the stock does. It moves in quarterly negotiations and long-term agreements, and in the fourth quarter it moved up twice over. TrendForce's forecast on 30 September put conventional DRAM contract prices at plus 10 to 15% quarter on quarter, with server DRAM undersupplied and PC DRAM supply possibly shrinking in 2027. Three weeks later its news desk, citing Commercial Times, reported roughly 20% for the same quarter, decelerating from about 80% in the second quarter and 40% in the third as ceilings in long-term agreements started to bite. Same house, both dated: the gap is a revised forecast, not a turning market.
Counterpoint Research told Invezz that industry DRAM revenue rose 369% year on year in the third quarter while bit shipments grew about 4%. "This is a pricing supercycle, not yet a volume cycle," said Jeongku Choi, a senior analyst there, adding that buyers are competing for supply rather than negotiating on price. SK Hynix's own quarter put DRAM average selling prices up a high-20s percentage in three months.
This article has no verified retail DDR5 kit price for the week of the selloff and will not invent one. What it has is the direction of the wholesale number retail is built from, which every dated print that fortnight put upward.
Sold out through 2029, eight days before the crash
On 28 October SK Hynix reported revenue above 100 trillion won for the first time and operating profit up 632% year on year. Management said DRAM and HBM volumes are effectively sold out through 2029, with more than half of 2027 and 2028 capacity committed to 14 customers and demand expected to outrun supply through 2030, per InvestorPlace. The Motley Fool had the stock closing that afternoon at $164.70, up 13.30%. Eight days later the same equity was falling double digits. Micron had told investors the same thing: 2027 and 2028 would be much tighter than 2026.
The two facts are not a contradiction; they are two clocks. A share price discounts profits far into the next decade, and the 2029 glut thesis is a claim about capacity arriving after the sold-out window closes. A contract prices the next four quarters and is signed by people who need the parts. Nvidia's Jensen Huang saw no sign of a glut and gave the reason in a sentence: "One of the things that's really great about memory is that you can always use more of it." He may be wrong about 2030 and still right about this winter.
What would actually have to break for DDR5 to get cheaper
Four things, in ascending order of how fast they could reach a shopping cart. The first is the negotiation: contract prices would have to stop rising, then fall, which needs inventory to build somewhere in the chain. TrendForce reports the opposite, with PC makers procuring aggressively on expectations that supply stays tight.
The second is fab capacity. Commodity DRAM gets cheap when advanced capacity is diverted back to it, and the diversion currently runs toward server and high-bandwidth parts. Consumer DRAM, TrendForce notes, is heavily reliant on Taiwanese suppliers who are themselves cutting production.
The third is China. CXMT's 4F² design could shrink cell area by about a third against the mainstream layout on paper, but TrendForce's round-up of Korean reporting says the announcement has yet to move spot prices, which kept rising, and that yields, leakage and retention still stand between the design and volume, with commercialisation expected after 2028. Elon Musk's post that China "will be making a LOT of RAM in 2028" is a post, not a purchase order, and CNBC noted the 2029 forecast has not been echoed by other analysts.
The fourth is a demand break, and it is the only one that works fast.
The strongest version of the cheap-RAM case
It is not the one in the post. A real air-pocket, with data-centre construction slowed by politics or by returns that fail to arrive, would cut hyperscaler orders, push HBM capacity back toward commodity parts and break spot pricing first, with retail kits following after a lag measured in quarters. The 2029 column is that case with a date attached: two Korean experts expecting a flood of new supply that turns the market into a red ocean. It is a coherent bear thesis about the end of the decade, and it says nothing about December.
The transmission channel is what local builders skip. Memory downturns do reach retail, but through inventory write-downs and contract resets, and by then the same downturn has usually taken the used market with it.
What to watch instead of the candle
Quarterly contract prints from TrendForce and its peers are the number that reaches a checkout page; a share price is a guess about them. Long-term-agreement language in the next earnings round will say whether the 2027 book is holding; PC DRAM allocation will say whether consumer parts get scarcer before they get cheaper.
If the RAM is needed now, Thursday changed nothing about the invoice. If it can wait, the signal to wait for is a contract print that turns negative, not a red candle on a chart. The post's joke works as a joke. As a forecast it reverses the causality: contract prices set the margins that shares discount, and in the same fortnight as the crash, those prices were still going up.
