South Korean equities rallied Thursday, carrying the benchmark Kospi index into a technical bull market. The full reversal from bear-market territory completed in just over a month, with AI-linked trading cited as the primary catalyst.
The classification rests on fixed conventions. A 20% decline from a recent peak defines a technical bear market; a 20% recovery from the subsequent trough defines a technical bull. The Kospi has now crossed both thresholds in sequence inside a compressed window.
That speed is the part worth examining. Recoveries grounded in improving fundamentals take longer to establish. What compresses into weeks is typically a positioning reversal, where capital that exited a specific theme flows back when the view on that theme shifts. The cited catalyst here is AI trade, a term that describes institutional flows into equities tied to artificial intelligence infrastructure and adoption.
AI-linked capital tends to move in concentrated blocks. When it rotates into a market, it can carry a benchmark index sharply within a short window. When it exits, the same logic runs in reverse. The Kospi's bear-market phase and its subsequent bull-market recovery appear to be two sides of that same repositioning dynamic, rather than separate stories with separate causes.
The bear-market decline and the bull-market recovery each ran at roughly comparable speed, with the full round trip completing in just over a month.
