To The Moon

The $NASDAQ(.IXIC)$ Composite closed 2.3 per cent higher on Monday at a record, its first since June; the $S&P 500(.SPX)$ closed 1.49 per cent higher at 7,764.70, which leaves it 0.4 per cent short of its own record; the $Dow Jones(.DJI)$ closed 0.7 per cent higher. What brought risk appetite back was falling oil prices and lower Treasury yields, and no company put out an announcement that day big enough to move the whole market. The $Philadelphia Semiconductor Index(SOX)$ rose 4.3 per cent, a fifth straight session of gains. The distance that opened up between the three indices says that a handful of sectors did the lifting.

$ARM Holdings(ARM)$ led, closing 17.16 per cent higher at US$322.90, the biggest gain in the Nasdaq 100 that day; Intel closed 12.14 per cent higher at US$121.78 and $Advanced Micro Devices(AMD)$ 9.95 per cent higher at US$615.52, taking its market value above US$1 trillion at the close for the first time. None of the three put out any news of its own. What the market took as the reason was Muse, Meta's AI assistant, reaching number one among free apps in the US App Store.

From there the market shifted its reading of what the demand looks like: if people really do start using assistants that carry out tasks on their own at scale, what gets consumed is not only the GPUs used in training but the general-purpose CPUs in servers and the silicon at the edge, and that part of the bill has spent two years in the shadow of GPUs. Arm, Intel and AMD were bought on that reading. Nvidia and Broadcom were not — $NVIDIA(NVDA)$ closed 2.30 per cent higher at US$227.38 and $Broadcom(AVGO)$ 1.60 per cent higher at US$362.66. On the same AI theme, one side gained double digits and the other gained two points.

Two footnotes came from the supply side that day. Intel's chief executive, Lip-Bu Tan, said the company can meet only about half of the demand it is seeing. Piper Sandler started coverage of Arm the same day at overweight with a target price of US$320; Arm closed the session at US$322.90, above that target. The sell-side number was written against the previous session's price, and the market cleared it inside a single day.

$Meta Platforms, Inc.(META)$ itself closed 11.43 per cent higher at US$741.25, its best day since April 2025. Muse launched on 8 September, and Sensor Tower puts downloads at around 2.5 million over its first two weeks; Wells Fargo lifted its target price to US$796 the same day, and the company's annual Connect conference falls in that week. What the market has doubted about Meta for a year is whether it can still build a consumer product that people actually use, and Muse answers that directly. What it does not answer is the half that comes after: there is a long stretch between downloads and revenue, the top spot among free apps can change hands within days, and a Meta executive has conceded the product is “heavily inspired” by OpenClaw.

Memory did not join in. $SanDisk Corp.(SNDK)$ closed 1.41 per cent lower at US$1,766.64, the only faller in that group, having closed 10.99 per cent higher in the previous session — the S&P 100 reshuffle took effect on Monday, the funds tracking the index had already switched their holdings at the last close before that, and no fresh bid arrived on the day it took effect. $Micron Technology(MU)$ closed 2.77 per cent higher at US$1,043.96, back above US$1,000, and SKHY 0.73 per cent higher at US$188.86; both were still up, just nothing like the chip names.

Two opposite readings turned up on the infrastructure side. $Marvell Technology(MRVL)$ closed 5.38 per cent higher at US$257.38, having shown 38 technology demonstrations at the European optical communications conference, among them what it calls the industry's first 2nm optical interconnect, pushing AI data centre networking from 1.6T towards 3.2T; that points at the wall beyond compute, where the silicon keeps getting faster while the bandwidth and power needed to connect it sit close to their limits. $NEBIUS(NBIS)$ closed 4.14 per cent higher at US$232.80, and on the same day Rothschild Redburn put both it and CoreWeave at sell, citing falling GPU rental prices, hyperscalers building their own capacity and expensive financing. The company selling the connection is paid out of its customers' capital budgets; the company renting out compute is paid in rent, and the rent is coming down.

Taken apart, what was repriced on Monday was an entire processor chain, and the basis given for it was where one free app sits in an app store. That position can change hands within days, while the contracts for capacity, foundry work and packaging are signed by the year. What the market bought that day was a change in the shape of demand, not anything a company had newly said out loud.

The above is personal analysis, not investment advice.

💬 【Talking Point】

$Intel(INTC)$ chief executive said on Monday that the company can meet only about half of the demand it is seeing, and Piper Sandler put a US$320 target on $ARM Holdings(ARM)$ that same day, which the shares had already passed by the close at US$322.90. What would have to show up in an order book before that CPU-side demand counts as real?
