Goldman Sachs has reaffirmed its target of 12,000 for South Korea's KOSPI index, a call that hinges on booming demand for AI memory chips and projected earnings growth of 300-360% for Korean stocks. The bank's latest stance, reiterated in a research note, keeps the index on a path that would mark a substantial climb from current levels, though the exact gap was not specified.
Why the target holds
The 12,000 target is not new, but the reaffirmation carries weight because it comes with a specific earnings forecast. Goldman Sachs projects that South Korean companies will see earnings grow by 300-360%, a range that would justify a much higher index valuation. The driver, according to the bank, is AI memory demand — the chips that power data centers and large language models.
Memory chips are a cornerstone of South Korea's export economy, and the AI boom has turned them into a strategic commodity. Goldman Sachs sees this demand as durable enough to lift corporate profits across the board, not just at the largest semiconductor makers.
The AI memory engine
AI systems require vast amounts of high-bandwidth memory, and South Korean manufacturers are among the few suppliers capable of producing it at scale. That positions the country's tech sector to capture a disproportionate share of the AI spending wave. The bank's analysts argue that this is not a short-term cycle but a structural shift in how memory is consumed.
If earnings grow at the projected pace, the KOSPI's current valuation would look stretched in the other direction — too cheap, not too expensive. That is the core of the bullish case.
What's at stake
The 300-360% earnings growth figure is aggressive. It implies that Korean companies will nearly quadruple profits, a feat that would require not just AI memory demand but also disciplined pricing and stable global demand for other exports. Any slowdown in AI infrastructure spending, or a supply glut in memory chips, could knock the target off course.
For investors, the reaffirmation is a signal that Goldman Sachs sees the risk-reward as favorable even after a strong run in Korean equities. But the target is not a guarantee — it is a forecast based on a specific set of assumptions about the AI cycle.
The next test will come when South Korean companies report quarterly earnings. If the numbers start to approach the bank's projections, the 12,000 target will look more credible. If they fall short, the call will face pressure. For now, Goldman Sachs is sticking with its number.
