An unusual scene played out on the U.S. New York stock market. Semiconductor-related companies occupied all of the top five spots by trading volume, yet every single one of these stocks closed lower. According to U.S. market closing data confirmed as of the morning of the 9th, Korean time, the top five by trading volume were Micron Technology (MU), Nvidia (NVDA), SanDisk (SNDK), AMD (AMD), and Intel (INTC), in that order. The combined trading volume of these five stocks amounted to approximately $99.276 billion.

■ Micron Tops Trading Volume, Falls 4.79%

Micron Technology drew the heaviest trading volume. Micron closed at $1,035.84, down $52.16 (4.79%) from the previous session, on a trading volume of 28,937,571 shares worth approximately $30.464 billion. Micron is a representative memory semiconductor stock tied to expanding AI data center investment and demand for high-bandwidth memory (HBM). However, its share price fell more than 4% that day, in contrast to its top ranking in trading volume.

■ Nvidia Falls 2.94%... Follow-up Trading in Focus

Nvidia could not escape the decline either. Nvidia finished trading at $230.48, down $6.99 (2.94%), with a trading volume of 114,314,945 shares worth approximately $26.589 billion. It is noteworthy that even Nvidia, regarded as a core company in the AI semiconductor market, showed weakness. Nvidia's price movements are tied to market interest in AI-related tech stocks overall, so attention is focused on subsequent trading as well.

■ SanDisk Falls 4.90%... Weakness Extends to Storage

SanDisk, third by trading volume, also fell sharply. SanDisk ended the session at $1,609.46, down $82.96 (4.90%), on a trading volume of 9,081,854 shares worth approximately $14.742 billion. With companies related to data storage joining the decline alongside AI semiconductor makers, the broad weakness across related tech stocks became even more pronounced.

■ AMD Falls 3.90%

AMD closed at $620.68, down $25.18 (3.90%), recording a trading volume of 23,318,883 shares worth approximately $14.595 billion. AMD, which competes with Nvidia in the AI accelerator and server processor markets, also could not escape the downward trend.

■ Intel Posts Largest Decline... Down 5.34%

Among the top five, Intel posted the steepest drop. Intel fell $6.04 (5.34%) to $107.08, with a trading volume of 118,360,006 shares totaling approximately $12.786 billion. Intel declined more than 5%, showing a larger drop than the other top-ranked stocks.

■ High Trading Volume Does Not Necessarily Mean Rising Prices

What stands out in this trading session is not merely the fact that semiconductor stocks fell. Micron and SanDisk operate in memory and storage, Nvidia and AMD in AI computing semiconductors, and Intel in CPUs and semiconductor manufacturing. Companies in different sectors occupied the top ranks by trading volume while declining simultaneously.

Judging by the trading volume rankings alone, it is clear that market attention was focused on semiconductor-related companies. However, high trading volume does not necessarily indicate buying dominance or rising share prices, as prices can fall even amid active trading. On this day, the five stocks' declines ranged from 2.94% to 5.34%, with memory and storage-related companies falling in the 4% range and Intel dropping more than 5%.

Long-term growth expectations for the AI industry and the short-term price movements of individual stocks can move differently. This session again demonstrated that strong interest in an industry does not mean the share prices of related companies rise in unison. The key point to watch going forward is whether this simultaneous weakness remains a temporary correction or develops into broader volatility across semiconductor-related stocks. The fact that semiconductor companies, which hold a substantial share of the U.S. tech stock market, dominated the top of the trading volume rankings while falling together is worth watching in the next session as well.
