Semiconductor giants take a major hit:
• SK Hynix 📉 over 10%
• Samsung 📉 7.5%#KOSPI #Sensex #Nifty https://t.co/COyS19dcCc
Yeah, 10% in a day is nuts. KOSPI plunged ~9-10% today, triggering a 20-min circuit breaker.

Samsung Electronics and SK Hynix (huge % of the index) led the drop, down 10-12%+.
Why? Profit-taking after the massive AI/chip rally + fears valuations got stretched. Spillover from US…
👆Blogged this exact setup yesterday on the S. Korea/Japan bubble... and boom — KOSPI -10% today on massive semiconductor rout. Media still refuses to say the word 'semiconductor' out loud. Global 'tech selloff', 'SpaceX', Iran nonsense. #RiggedAF #Chips #TechnicalTuesday

Verified Pro Trader @GarethSoloway: KOSPI (South Korea) drops 10% hitting circuit breakers. 2 semiconductor stocks make up over 50% of that index. NASDAQ futures drop over 700 points as the AI trade hits a wall. Worries mounting on on cheaper AI models.
