If you saw the markets this morning and thought to yourself, this can’t be right, you are not alone. South Korea’s Kospi had its worst day in years, and with it came what looks to be a slow correction of sorts
.
The Numbers tell the story of a market seemingly free-falling, with the kind of volatility only seen during true bear markets
South Korea’s Kospi finished the day down 10.8% at 6,023.66, its lowest level since April. After initially dropping more than 14%, trading was temporarily halted for 20 minutes due to circuit breakers, in an effort to allow the market to cool off
A large part of the sell-off was driven by technology stocks, which had previously powered the markets higher.
Samsung Electronics fell 13.4% and SK Hynix dropped 14.7%, with the latter’s shares on the New York Stock Exchange plunging below the $149 IPO price from its recent Wall Street debut, closing around $143 , a sign that investors are looking past any growth in the sector
Samsung and SK Hynix account for nearly half of the value of the Kospi, meaning their precipitous falls triggered large losses for the broader market.
However, South Korea was not alone, as similar weakness was seen across the region. Japan’s Nikkei 225 fell some 4%, with the Topix composite index down 2.4%. Shares in Taiwan’s Taiex were also lower, down 3.9%, with Hong Kong’s Hang Seng and China’s Shanghai Composite each seeing modest losses of 0.1% and 1%, respectively. The lone bright spot came in Australia, where the ASX 200 was up 0.6%. In the US, futures for the Nasdaq 100 were down around 1%, with S&P 500 futures also lower, down 0.3%, while Dow Jones index futures rose slightly
What This Means For Investors
Simply put, the market’s reaction to today’s news is the realization that the AI boom may well be getting ahead of itself, and once that thought takes hold, it can be very difficult to reverse. A number of catalysts appear to have come together this week, notably a large and exciting IPO in the Chinese market, which may very well be fueling some speculative short-term buying in markets.
Chinese chipmaker CXMT saw its shares rise 466% in their Shanghai debut, after raising some $8.6 billion on the Shanghai STAR Market, in what was seen as a huge listing for the tech-focused exchange
At the same time, China appears to be making significant progress in its efforts to localize its semiconductor manufacturing. Notably, it was reported this week that China has started serial production of its own deep ultraviolet lithography machines.
These are the machines used to make chips, and they have long been considered to be the weak link in China’s efforts to localize its semiconductor industry. If China is able to achieve true self-sufficiency in this arena, it would reduce the importance of firms like Samsung and SK Hynix, as well as limiting the influence of equipment manufacturers based in the US and the Netherlands.
Meanwhile, simply put, valuations for AI related stocks have gotten ahead of themselves, and once that realization takes hold, it can fuel a rethink of entire sectors.
Is This The End Of The Road For AI Stocks, Or Simply A Correction?
In many ways, this is a self-limiting issue, as markets have seen similar bouts of selling related to AI stocks before, and in many cases, those fears have been misplaced. Tech stocks in general have seen a number of corrections throughout the past year, with a number of them selling off sharply due to fears of a tightening monetary policy in the US. With that said, this sort of broad sell-off is rarely the beginning of the end for a given sector, but rather a reset, with investors taking profits on their positions or rethinking their exposure to a given sector
It is impossible to say if this particular correction will lead to a broad sell-off for AI related stocks, but it is notable that several years into this boom, there are now legitimate concerns about the ability of these firms to grow their revenues and profits in the years to come. With that said, tech stocks as a whole have continued to do well over the course of the past year, with most of them continuing to see gains on a year-to-date basis, despite the fears about the sustainability of their growth rates.
What Individual Investors Should Do Now
It is important for individual investors to not get caught up in the panic selling that often accompanies broad market corrections. That means selling individual names only after further analysis, rather than reacting to the panic selling of the overall market. Similarly, it is important for investors to remember their reasons for buying in the first place, and consider carefully if those reasons still exist, rather than selling immediately in the wake of a correction. It is worth noting that large corrections often come on the heels of bear markets, but it is too early to say if this particular correction is the beginning of such a market.
The Bottom Line
The Kospi’s near 11% loss is a sobering reminder that the AI trade is extremely focused around a relatively few number of companies, and those companies are capable of driving large swings in the markets in which they are listed. In particular, Samsung and SK Hynix, two of the largest firms in South Korea, are capable of pushing the Kospi down by nearly double digits if fears about their prospects mount. At the same time, fears about competition from Chinese firms are also beginning to take hold, and that will likely put additional downward pressure on the shares of firms like Samsung and SK Hynix, at least in the short-term.
Whether the current correction turns into a broad sell-off for AI related stocks remains to be seen, but one thing is certain; chip stocks are sure to make headlines in the weeks and months to come.
