Reminiscence shares received hammered this week after Google dropped a analysis paper that has buyers questioning the complete thesis for the AI-driven reminiscence bull run. Alphabet’s (GOOGL) Google Analysis group printed particulars on Tuesday of a brand new compression algorithm referred to as TurboQuant, and the fallout was swift. Sandisk Company (SNDK) plunged as a lot as 11%, Micron Expertise (MU) dropped 7% on Thursday because the promoting accelerated, and Western Digital and Seagate every fell over 7%. The injury prolonged abroad, with Samsung and SK Hynix each sliding greater than 5% in Seoul. As of this morning, the group is rebounding.
Each Micron and SanDisk presently carry a Zacks Rank #1 (Sturdy Purchase). The provision constrained dynamic and distinctive demand for DRAM has pushed these shares to unbelievable performances within the final six months, with SNDK up practically 5x and MU greater than doubling over that interval.
So is Alphabet constructing a know-how that destroys the bull case for this area of interest AI infrastructure increase? Or is that this a case of headline-driven profit-taking in an overextended sector?

What Alphabet’s TurboQuant Truly Does
At its core, TurboQuant addresses some of the costly bottlenecks in working massive language fashions: the key-value (KV) cache. That is the high-speed knowledge retailer that retains context so a mannequin would not need to recompute all the pieces with every new token it generates. As fashions course of longer inputs, the KV cache balloons, consuming GPU reminiscence that would in any other case serve extra customers or run bigger fashions.
Google’s algorithm compresses the KV cache considerably, lowering its reminiscence footprint by practically 6x with out sacrificing accuracy or requiring mannequin retraining. Examined throughout 5 customary AI fashions, TurboQuant achieved good scores on retrieval duties. Testing confirmed that it delivered as much as an 8x acceleration in computing consideration on Nvidia H100 GPUs.
Past LLMs, Alphabet famous that TurboQuant additionally improves vector search, the know-how underpinning all the pieces from Google Search to YouTube suggestions to advert focusing on.
Reminiscence Shares Micron and Sandisk Promote Off Sharply
The sell-off in Micron, Sandisk, and their reminiscence friends echoed the DeepSeek-driven panic from early 2025, when a Chinese language AI lab demonstrated that aggressive fashions might be skilled with far much less compute than assumed. That episode triggered a one-day bloodbath in semiconductor names earlier than the market in the end concluded that effectivity beneficial properties speed up adoption, and adoption drives extra {hardware} demand, not much less.
The identical logic might apply right here. TurboQuant compresses knowledge throughout inference, not coaching. That is an vital distinction. AI mannequin coaching, which is the place essentially the most reminiscence consumption happens, is actually unaffected by this algorithm. Excessive Bandwidth Reminiscence (HBM), the product class driving the strongest income development at Micron and its friends, stays important for coaching workloads.
There’s additionally the Jevons paradox to contemplate: by making AI inference cheaper and extra memory-efficient, TurboQuant might speed up the deployment of LLMs into edge units, smartphones, and IoT functions, all classes that may create totally new reminiscence demand that does not exist at this time.
SNDK and MU Inventory’s Nonetheless Boast Tailwinds
Micron’s earnings final week had been fairly distinctive. The corporate delivered February-quarter earnings that beat steering by 45%, and its Might-quarter earnings steering successfully doubled consensus estimates. Income practically tripled year-over-year, and web earnings surged virtually 10x. MU presently trades at roughly 6x ahead earnings, the most affordable ahead P/E in the complete S&P 500 after its current 23% post-earnings slide from report highs.
SanDisk’s fundamentals inform an identical story. SNDK reported Q2 fiscal 2026 EPS of $6.20, beating forecasts by practically 78%, with income up 61% year-over-year. Gross margins expanded dramatically to 51.1% from 29.9% within the prior quarter, and administration guided Q3 income to $4.4–$4.8 billion with gross margins of 65–67%. The corporate is actively signing long-term provide agreements and projecting 75–100 exabytes of AI-related storage demand by 2027.
Whereas investor focus stays fixated on Alphabet’s analysis breakthroughs, the extra related danger to those shares is just not technological obsolescence pushed by analysis, however the inherently cyclical nature of the reminiscence and storage trade itself. Traditionally, these companies have been outlined by intervals of undersupply adopted by aggressive capability growth, which in the end results in pricing stress and margin compression. In that context, the eventual finish of this cycle is much extra more likely to be pushed by supply-demand dynamics normalizing than by any single leap ahead in AI capabilities.
Within the chart beneath, we will see that Micron inventory has traded right down to a transparent stage of assist following the earnings, and Alphabet information pushed selloff. For now, it seems to be holding at assist. Traders can control this stage to find out the place the following transfer could also be.

The AI Buildout Exhibits Few Indicators of Slowing
Alphabet’s TurboQuant is a authentic technical achievement. It should doubtless cut back the price of AI inference over time, and GOOGL stands to learn straight by decrease working prices throughout its cloud and search infrastructure. However the leap from “6x compression of the KV cache” to “the AI reminiscence increase is over” could also be a story stretched too far.
The reminiscence cycle is pushed by supply-demand dynamics that function on multi-year capex timelines, not by particular person analysis papers. Samsung, SK Hynix, and Micron have all constrained provide in current quarters exactly as a result of the trade discovered its lesson from the brutal 2022–2023 downturn. Demand from hyperscale knowledge middle buildouts, the place Meta alone lately dedicated $27 billion in a single take care of Nebius, exhibits no indicators of abating.
For buyers in Micron and SanDisk, this week’s pullback appears to be like extra like a present than a warning. Each shares are Zacks Rank #1 names with accelerating earnings, strengthening margins, and valuations which have moderated within the final couple of weeks.
