Lofty Valuations Trigger AI Stock Reassessment as Emerging Market Assets Suffer Three-Day Losing Streak
Claire Weston
Broadcom's AI chip sales guidance fell short of sky-high expectations, sparking a global tech selloff — the MSCI Emerging Markets Index dropped 1.7% for a third straight day, with South Korea plunging as much as 7% intraday and erasing two weeks of gains.
What lit the fuse?
U.S. chip designer Broadcom issued AI chip sales guidance that fell short of the market's elevated expectations, triggering a broad tech selloff.
This means → the market had priced AI stocks to perfection; the moment guidance came in merely "good" instead of "great," a valuation reset kicked in.
In plain terms = investors gave AI stocks a perfect score in advance — Broadcom's report card came back a B+, and the whole sector got marked down.
Why did South Korea take the hardest hit?
The KOSPI plunged as much as 7% intraday, led by Samsung Electronics and SK Hynix — together accounting for over half of Korea's total market cap.
This means → Korea's stock market is heavily tied to the semiconductor supply chain; any wobble in AI chip expectations hits Seoul first.
Foreign investors continued to dump Korean equities, pushing the won down 0.8% — the worst-performing Asian currency of the day.
How badly were emerging markets hit overall?
The MSCI Emerging Markets Index fell 1.7% to 1,728.66, marking its third consecutive daily decline and snapping a two-week rally.
The developing-country currency index dropped 0.3% for a fourth straight session — capital is pulling out of emerging markets across the board.
This reflects a key point: AI's valuation reset is not just a tech-sector story — it is spilling into emerging-market equities and currencies through capital flows.
What risks are still lining up?
Markets are awaiting the U.S. nonfarm payrolls report for clues on the Fed's rate path. Saxo Markets chief investment strategist Charu Chanana warned that a stronger-than-expected jobs number could push investors to unwind crowded AI positions further.
In plain terms = strong jobs data → Fed rate cuts pushed further out → higher cost of capital → overvalued AI stocks sold first.
Meanwhile, U.S.–Iran peace talks have stalled and Hezbollah has rejected a U.S.-brokered ceasefire, adding fresh geopolitical pressure on risk assets.
