Sensex, Nifty face global selloff as Kospi, Nikkei tumble like a house of cards; here's why

BSE is in focus.

· Business Today Mkts

Korea's Kospi tumbled 7.6 per cent with chipmakers such as Samsung Electronics and SK Hynix plunging 9 per cent each. Japan's Nikkei was trading 4.53 per cent lower at 64,659.88.

BSE reported movement of 9%, 7.6% and 4.53%. Those are the figures as filed — what moves the price is how they sit against what the market already expected, not their absolute size.

Because the driver here is macro rather than company-specific, the read-through is to index-level positioning rather than to any single name — correlations tend to rise when the whole market faces the same signal.

  • With BSE involved, this carries a regulatory dimension that can outlast the immediate market reaction.
  • This is a market-wide development — its reach goes beyond any single stock.
