The chip sector of the Korean and US stock market sold off sharply this morning on the news that a firm in China announced at a conference that it has made a significant step forward in the craft of manufacturing memory chips. Elon Musk apparently observed that China normally has significant scale in manufacturing in just about everything, so a new-and-better chip might make significant inroads in the current chip market. Arguably worse, it might decide to withhold the advance from the rest of the world, compelling potential users to set up shop in China.

Chip stocks were looking a bit toppy before this news, so the resulting selloff in Korea and the US can’t come as a huge shock. Several key characteristics of the current administration make the situation significantly riskier than it otherwise might be, however: the attack on universities, ICE, and the aversion to people with technical expertise. The US has also decided to deny China access to the most advanced chip-making tools from ASML, forcing it to intensify its own development efforts.

So one might also ask whether the shoe isn’t now on the other foot–with China moving ahead of the rest of the world and potentially opting to withhold its advances from the US.

In different times, the market would find this situation a reason to rotate away from IT to, say, Consumer Discretionary names. But Washington’s economics of tariffs and shrinking the workforce, as well as the visions of 1930s Europe its policies conjure up, have stunted profit growth there and diminished the value of the sector’s brand names and distribution networks.

Some consumer names have been showing strength over the past short while, but I don’t see any strong pattern to the sectors ups and downs. But it’s at least worth thinking about how to react to upcoming election results.

Over the past short while, I’ve been reading lots of comments about how apparently lopsided, or AI-tilted, the current US stock market is. The general argument is that if there’s some bad development in the AI space, the S&P and NASDAQ have nothing much else going for them.

I agree that this is the case. But there’s also another side to the coin, one that I think is just as important. It’s that, ex AI, the US economy doesn’t have much going for it at all–due in large part, I think, to the high level of incompetence on both sides of the aisle in Washington. Although almost half a century as a professional investor has taught me that government policy never really matters that much. Not so right now, I think.

Two conclusions:

–it isn’t completely that AI is so dominant, it’s also that the general domestic economy is in poor shape and that current federal government policy has given the US as a place a tremendous black eye. Joining North Korea and the Taliban as one of the few entities to televise executions is probably not a feather in our cap, either.

–for the first time in a very long while, US election results may well play a significant role in the direction of the stock market into next year. The question to be answered is whether it still makes sense, as it has since the inauguration, to avoid the general US economy as much as possible.

I wasn’t quite sure how to headline this. The FT and its parent the Nikkei News are, in my view, the two best sources of usable, professionally written, articles on the world economy in general and on individual publicly-traded companies.

One of the FT’s regular contributors is Mohammed El Erian, whom copilot describes as an accomplished global macro strategist. What I enjoy most about Mr. El Arian is his elegant and sophisticated use of the English language. In today’s newspaper, for example, he makes the point that current Treasury intervention in markets “to counter underlying market fundamentals” is counterproductive. It risks “eroding credibility” and “Using it as a routine policy lever rather than an emergency safety valve risks turning a market stabilizer into a source of moral hazard and deeper volatility.”

To the extent I understand Mr. El Erian’s prose style, he’s saying this is shockingly bad policy.

Memory chips are a boom and bust business that is already very capital intensive, and increasingly so. The dilemma for investors is this–the stocks have already gone up a lot and the industry has already planted the seeds of its own future downturn in the immense capacity expansions now underway. On the other hand, these additions are still several years off.

A side issue, which may end up becoming important at some point, is that China appears to have unused capacity. Sanctions have prevented that country from obtaining cutting edge chip-making equipment from ASML and also deter western product makers from using Chinese output of any type. We’ve already seen gamers begin to make the shift–as well as Chinese chip makeers raise prices.

Let’s put that to the side for now.

The big issue that investors are struggling with is that we know that, with or without China, the current boom will end within a few years and we surmise that the usual trainwreck will then ensue as massive new capacity come online, virtually all at once. On the other hand, Micron (MU) is still only trading at 14x earnings, even after having tripled so far this year. And it would be very unusual for the market to discount today capacity additions that are at least a couple of years in the future.

The newest piece of information that has come out is the Samsung Electronics pre-announcement of very strong earnings growth in its latest quarter. More important, though, is the fact the stock went down on the news.

Personally, I sold the MU I owned a while ago and put most of the proceeds into a dram ETF. This is after having trimmed my overall tech exposure significantly a while ago and put that money into things like the NY Times and the Atlanta Braves. Given the trainwreck the administration has made of the US economy, it’s hard to know whether cash, or foreign stocks, wouldn’t be a better move.

But my main point is that the Samsung Electronics price action suggests that the DRAM trade may well be living on borrowed time.

I’ve updated my Keeping Score page for September and 3Q performance.

If we look at 2026 so far as a whole, that stands out to me is that two sectors, IT and Communication Services (where most of the AI firms reside) together make up 47% of the total index, according to Gemini.

In a sense, everything else is tiny in comparison. But two very small natural resource sectors, Energy and Materials, who are also big ytd winners, together also make up about 5% of the index. All this is to say that the remaining 48%, which represent the heart of the domestic economy, is significantly weaker than this year’s overall stock market strength–keeping pace with the rest of the world for the first time in this administration–would lead one to believe.

Typically, in situations like this the market has tended to experience what jargon lovers would call a counter-trend rally–where the ytd losers go up and the winners go down. No sign of this so far, though. No sign either of any takeover interest–foreign or domestic–in down-and-out domestic firms with powerful brand names and distribution networks. This is also an unusually pessimistic stance.

Still, there’s no sign I can see that the market has any inclination to change its very heavy, very successful bet (1) for AI and (2) continuance of Washington’s wildly dysfunctional handling of national affairs.

As for me personally, most of my family’s money is in index funds. I have one account I actively manage, though. Early in the year I shifted away from a heavy emphasis on mainline AI-related names to less well-known suppliers of components/services. A couple of months ago, I cut my tech overweight in half and bought industrial and service names in the US and EU. Conceptually, I’ve been wanting to get involved with beaten up low-end consumer names as well, on the idea that the domestic economy can’t be bungled much more badly than it has been and these firms have potentially valuable brand names and distribution networks (the basic Warren Buffett insight of a half-century ago). I haven’t acted yet because none of the stocks I’ve been eyeing have shown any signs of life.

I also think that the upcoming election could have a significant impact on stocks. Hard to know what that might be, however. The worst outcome for the S&P, I think, would be a vote of confidence that ICE violence, tariffs… are the way to go.
