Part of a longer stretch

Korea's dot-com hangover

early in it · 2000-01-04 → 2001-09-17, -55.74% over the whole period

What happened that day?

18 April 2000 — the KOSPI rose 5.59%
The previous session, 17 April, had wiped out a double-digit percentage in one day. This was the recoil
It started in the US. The Nasdaq broke down on Friday 14 April, and Korea absorbed all of it on the Monday
But the Nasdaq rebounded hard that same Monday night. Tuesday in Korea was that rebound arriving
Through this stretch the KOSPI tracked American tech a day behind — semiconductors and telecoms dominated the index
The bounce changed nothing. The episode low came in late May, 38.06% below the January high
That 17 April drop still ranks as the third-largest single day in KOSPI history
