Analysis-How a few AI chip giants warped Asia's stock picking game
Asian markets have been jolted by a 'Black Monday' unwind, as an AI-fueled rally in semiconductor giants like TSMC, Samsung, and SK Hynix abruptly reversed, triggering sharp sell-offs and forcing active fund managers to ditch their top-performing holdings. South Korea's Kospi plunged over 8% on June 8, reflecting growing fears that the eye-watering valuations in the AI sector had run ahead of fundamentals, exacerbated by a disappointing forecast from Broadcom and concerns over higher US interest rates. This dramatic correction highlights a structural trap, where the unprecedented concentration of these AI chip behemoths — comprising nearly a third of the MSCI Asia Pacific ex-Japan Index and over 50% of national benchmarks like the KOSPI — compels fund managers to sell due to risk compliance limits, regardless of underlying performance. The situation has warped traditional stock picking, accelerating a massive flight of capital from active to passive investment strategies across Asia, with billions flowing out of actively managed funds in recent months.
