# A Build Delay Hit Sold-Out Suppliers: Why Timing Is Not Demand

Thursday was one of the hardest days for technology investors in decades. The Philadelphia Semiconductor Index fell 12.25%, its second-worst day since the 1990s. The Nasdaq fell 5.5% into a correction and the S&P 500 fell 4.4%. On Friday morning Korea halted trading for 20 minutes after an 8.5% drop. Here is what happened, what it means, and what the portfolio did.

## The damage

- Micron (MU) fell 17.5%, SanDisk 22%, Western Digital 17%, Seagate 16%, the SK hynix ADR 13%, NVIDIA (NVDA) about 9% and AMD about 15%.
- Korea’s KOSPI closed down 6% on Friday after the circuit breaker; SK hynix fell 10% and Samsung 6%. Japan fell about 6%.
- Volatility jumped about 65%. Retail investors sold on a scale not seen since March 2020.
- Gold fell about 1.6% overnight. On a forced-selling day it is a source of cash, not a safe haven.

## What the market is saying

On Wednesday I wrote that the right to build has become the next bottleneck for AI, after chips, tools and capital. On day two, the market sold the companies tied to a building site. On day three, it sold the suppliers.

The driver is political. After the US elections, investors fear stricter rules for new data centres, and one large bank estimates that the states most likely to tighten oversight hold about 45% of planned new US capacity. Most coverage calls it a question of **how fast** data centres get built, not whether the demand exists. On top of that, funds sold the most-owned winners of 2026 to lock in the year.

Here is the part I think the market is missing. The 2027 output of the leading memory and optics suppliers is largely contracted already:

- SK hynix has deposit-backed long-term agreements covering more than half of 2027–28.
- Coherent (COHR) says 2027 is basically booked out.
- Lumentum (LITE) has just added more than $5 billion of purchase commitments for co-packaged optics.

A slower build changes timing. A contract only changes if an order is cancelled. So far, no large cloud buyer has cancelled anything or cut its 2027 spending plan.

There is also a new detail. Applied Optoelectronics (AAOI) reported strong growth (revenue up 128% year on year), but said its own 2027 US factory expansion is delayed by power access and construction. The power and permit bottleneck is now slowing the suppliers’ factories too. If new supply arrives later, the shortage lasts longer, which favours whoever already has the capacity, such as TSMC (TSM), Coherent and SK hynix.

## What the portfolio did

- The portfolio fell about 3.1%, against −4.4% for the S&P 500 and −5.5% for the Nasdaq, on a day the chip index fell 12%.
- Cash (about 18%), short-term inflation-protected bonds, Treasuries, utilities, consumer staples, solar, China and health care cushioned the drop. Several defensive lines are still in profit.
- Three stops filled at their levels with almost no slippage: the health care ETF, the S&P 500 ETF and Berkshire Hathaway (BRK.B), which was closed before its Saturday results.
- Following the plan for corrections, part of the cash was used to average down into already-researched holdings at full standard clip size: memory, semiconductors, TSMC, ASML, Broadcom, uranium, Korea and Samsung. Tax-loss clips were reset at the same time.

## What comes next (written in advance)

1. **Friday:** the US jobs report and Vistra (VST) results before the open. Hold Vistra if its 20-year nuclear power deal with Amazon is reaffirmed; exit at the close if Texas load-growth guidance is cut or the moratorium is called material.
2. **Tuesday:** US inflation (CPI). If it is not hot, the next tranche goes only to contracted suppliers: TSMC, ASML and Coherent.
3. A further tranche only if chips fall roughly another 10%, or a large cloud buyer reaffirms its 2027 spending.
4. Everything pauses if a hyperscaler names data-centre cancellations or cuts its 2027 capex. That would turn a timing story into a demand story.
5. No new Korea adds while Seoul trades down 3% or more.

## Risks, stated openly

- This may be a regime shift, not a flush. If AI hardware stops moving as one trade, picking the right names matters more than buying the dip.
- Korea can halt again, and European listings of Asian stocks gap when Asia is shut.
- Oil is back near $100, which could push inflation and yields up.
- Friday combines a jobs report and a major earnings release in the same session, so expect volatility.

## The process

A 12% chip crash cost the portfolio about 3%. That gap is the hedges and the cash doing their job. Crashes don’t reward the boldest; they reward the people who wrote down their levels before the panic and stick to them. The plan is to keep spending in steps, only where the evidence is contracted, and to keep the rest ready.
