Analyst Warns Samsung and SK Hynix Stocks Could Peak in Early 2027 Despite the current euphoria, a prominent analyst cautioned that Samsung and SK Hynix stocks could see their cycle peak in early 2027, citing the semiconductor supply cycle and foreign investment limits. The warning comes as the KOSPI approaches uncharted territory, with both chipmakers now accounting for an unprecedented share of the benchmark index. The caution reflects broader concerns that the AI-driven demand surge, while real, may be getting priced in ahead of fundamentals.
What to Watch
- Samsung Strike Watch: The potential for a workers' strike at Samsung Electronics is the most immediate risk to the chipmaker's stock relative to SK Hynix. Monitor for developments from Samsung's unionized labor organization in the days ahead.
- SK Hynix Target Price Upgrades: With multiple brokerages now setting targets of 2.0–2.1 million won per share, watch for whether continued AI infrastructure orders from hyperscalers confirm or disappoint the bullish consensus at SK Hynix's next earnings update.
- Upstage and AI Startup Funding Cadence: Following the $380.6M regulatory approval for Upstage, track whether other Korean AI startups attract similar scale investment rounds — particularly as the government's $5.7B National Growth Fund begins deployment.
