Micron Shares Plunge 13% After Warning on Risky Chip ETFs

Micron shares experienced a significant decline of over 13% on Tuesday, largely attributed to a global chip sell-off triggered by South Korea's Financial Supervisory Service's warning about risky exchange-traded funds (ETFs) tied to memory chip companies like Samsung and SK Hynix. The warning highlighted the high-risk nature of these funds, which can amplify daily price movements by two or three times.

The drop in Micron's stock came after Financial Supervisory Service Governor Lee Chan-jin expressed regret over not blocking the launch of leveraged ETFs solely tracking Samsung and SK Hynix. Investors, particularly retail individuals, have engaged with these funds despite the high-risk warnings. This has raised concerns about whether Micron's astronomical stock run this year is driven by momentum trading rather than fundamentals.

Leveraged single stock ETFs are designed for short-term trading and can pose significant risks to investors. They can double or triple gains or losses in a single day, which can be particularly challenging for retail investors who may not fully understand the risks involved. As Micron has soared over 260% since the start of the year, questions have been raised about the sustainability of its stock run.

In an interview with Bloomberg, Lee stated that about 92% of holders of these high-risk products are retail investors. Despite consumer warnings, trading hasn't cooled. This has significant implications for the broader market, as momentum trading can lead to market volatility. The statement has sparked concerns about the potential consequences of relying on momentum trading rather than fundamental analysis.

Micron's stock closed down 13.3% at $1,051.77, erasing two day's worth of significant gains made by the stock on Friday and Monday. The sharp decline has left many investors wondering whether the drop was a result of anxiety before Micron's earnings report, which tends to act as a gauge for AI demand. However, the warning on risky ETFs has added nervousness to the market, particularly in the context of a potential rise in interest rates by December.

Analysts have attributed the decline in Micron's stock to a selloff that may have been triggered by anxiety before the earnings report. However, some have also noted that the market is experiencing a 'gut check moment.' This has led to significant declines in other chip and memory stocks, including Nvidia and Intel. The overall market impact of the warning on risky ETFs remains to be seen.

The impact of the warning on risky ETFs is not limited to Micron alone. Several other chip and memory stocks have also tumbled ahead of Micron's earnings report. Nvidia's stock fell by over 4%, while AMD shares dropped nearly 6% and Intel's stock declined by 6.1%. The warning has added nervousness to the market, particularly in the context of a potential rise in interest rates by December.
