Samsung and SK Hynix plunge together
U.S. data center regulation concerns

In short
On November 5, Samsung Electronics and SK Hynix stock prices fell sharply.
This is because the Democratic Party won both chambers in the U.S. midterm elections.
Concerns grew that if Democrats regulate AI data center construction, memory chip demand could decline.

What it means for me
If you hold funds or pension products with high semiconductor stock allocations, watch for short-term volatility.
If your retirement pension or private pension includes semiconductor-related funds, it may be worth checking yield changes.
If your portfolio focuses on dividend stocks or stable products, the direct impact from this plunge is limited.
