## KOSPI Drops Below 5,000
South Korea's KOSPI closed at 5,059.69 on Nov. 6, down 6.02% from the previous session after U.S. data center regulation fears.
## Market Focus on AI Regulation Impact
Brokerages say the decline is excessive but a V-shaped rebound is unlikely due to Anthropic's IPO and data center earnings.
## U.S. Data Center Regulation Concerns
U.S. midterm election results fueled fears that data center construction delays could curb AI investment in South Korea.
## Semiconductor Sector Impact
Semiconductor stocks fell sharply as concerns over AI investment profitability and supply-demand conditions grew.
## Brokerage Analysis on Regulation
Yoon Seok-mo warned that permitting procedures for data centers could become more onerous, delaying construction.
## AI Investment Profitability Doubts
Lee Jin-woo noted that doubts about AI profitability and funding had been building, exacerbated by the midterm election results.
## Valuation Metrics Show Oversold Market
The KOSPI's 12-month forward PER fell to a record low of 3.77 times, indicating an oversold market.
## Anthropic IPO Impact
Anthropic's $100 billion IPO, targeting a Nasdaq listing by November 26, could pressure semiconductor stocks.
## Foreign Selling Pressure
Brokerages expect foreign selling to ease as U.S. inflation and interest rates stabilize.
## Short-Term Rebound Expectations
Analysts predict a slow rebound over weeks, not a quick V-shaped recovery, due to unresolved data center delays.
## Key Watchpoints for Recovery
The KOSPI's direction depends on data center regulation scope, CoreWeave and Nebius earnings, and U.S. inflation data.
## Key takeaway

South Korea's KOSPI fell below 5,000 due to U.S. AI data center regulation concerns, with brokerages predicting a slow rebound.
