KOSPI (+2%) and Nikkei 225 (+1.5%) post gains amid tech-related optimism; ASX lags (-0.1%) amid a lack of relative exposure to the sector.

Sessions in which North Asian benchmarks rally on semiconductor and tech optimism while the ASX lags are a familiar pattern: the KOSPI's heavy weighting toward memory and chip names and the Nikkei's toward chip-adjacent industrials means a single strong lead from US tech or a sector-specific catalyst tends to lift both, while Australia's index, dominated by banks and resource producers, lacks that transmission channel and underperforms by construction rather than by idiosyncratic weakness. In past episodes of this kind the divergence has been a relative-value story, not a regional risk signal, and has tended to persist only as long as the underlying tech catalyst does, with the gap often mean-reverting when the semiconductor complex stalls. The distinction worth drawing is between a broad risk-on tape, which would lift the ASX's miners via the metals and commodity leg too, and a narrow sector rotation, which is what the flat Australian close alongside the North Asian gains suggests. The follow-ons are the session's breadth within Seoul and Tokyo, whether the move is concentrated in a handful of large-cap chip names, and how US futures and the next US tech session treat the same catalyst, since Asian tech sessions of this kind have historically taken their cue from the prior US close and handed the baton back.
