Kospi bull market 2026 hinges on AI chip demand and foreign buying

South Korea’s Kospi bull market 2026 is back in focus after the benchmark climbed more than 20% from its July low, meeting the widely used definition of a bull market. For investors, the rebound matters because the index is heavily shaped by a small group of semiconductor companies, so confidence in artificial-intelligence spending can quickly move the broader market.

CNBC reported that the July rout was driven partly by leveraged positions and forced selling, which pushed the Kospi into bear-market territory. The subsequent recovery came as those pressures eased and investors returned to major chip stocks.

A 20% rise is a market convention, not confirmation that a lasting new uptrend has begun. The next phase depends less on the rebound’s size than on whether the fundamental case for South Korean memory-chip makers keeps improving.

How long can the Kospi bull market last?

There is no evidence for a reliable timetable. Analysts cited by CNBC point to three tests: whether semiconductor earnings expectations keep rising, whether big technology companies continue spending on AI infrastructure, and whether foreign investors keep buying after short-covering fades.

Short-covering occurs when investors who had bet on lower prices buy shares to close those positions. It can intensify a rally without necessarily showing long-term conviction. Jung In Yun of Fibonacci Asset Management Global said foreign investors appeared to drive a sharp July 31 recovery, while short-covering and rebalancing by leveraged exchange-traded funds added to the move.

Stronger earnings from U.S. technology companies have supported the case that demand for memory chips will remain solid, CNBC reported. Peter Kim, KB Securities’ head of global investment strategy, said the earlier selloff reflected technical market forces and fund flows rather than a serious break in semiconductor valuations or earnings expectations. He also said the unwinding of leveraged positions had eased after regulators and brokerages tightened requirements.

Why AI spending has an outsized effect on Korea

The Kospi’s concentration in semiconductor leaders makes it especially sensitive to the AI-hardware cycle. Phillip Wool, head of research at Rayliant Global Advisors, told CNBC that stronger-than-expected earnings from large U.S. technology companies reinforced expectations for AI infrastructure spending and led to higher growth forecasts for Korean hardware businesses.

That concentration cuts both ways. Wool said softer capital-expenditure guidance from hyperscalers, companies that operate large cloud-computing platforms, pressure on token pricing, or fears of tighter Federal Reserve policy could prompt a pullback. He expects volatility while investors remain uncertain about the course of AI-hardware spending.

Reforms could support the longer-term case

Billy Leung, an investment strategist at Global X ETFs, also pointed to South Korea’s corporate-governance reforms and its Value-Up program. Those efforts are intended to reduce the “Korea discount,” the longstanding tendency for South Korean companies to trade at lower valuations than comparable global peers.

Leung said the rally appeared closer to one backed by improving fundamentals than speculation, though he flagged elevated retail participation, index concentration and ambitious market targets as signs associated with a later stage of a market advance. Yun offered a similarly cautious view: the recovery reflects both a technical bounce from forced selling and a return of stability, but a slower and more uneven climb would be more plausible after such a steep rebound.

For now, continued foreign buying and resilient AI investment signals would strengthen the case for a durable recovery. A renewed leverage squeeze or weaker chip-demand outlook would test it quickly.
