Semiconductor Stocks Hit Most Overbought Since Dot-Com Peak

The semiconductor sector (SOX, SOXL) has become the market's most crowded trade, with memory stocks (MU, SNDK) and foundries (TSM) rallying 30% in a single week on "supercycle" rhetoric. The underlying fundamentals are not trivial: AI server demand is real, and memory-chip makers are reporting margin expansion timelines stretching into 2027. However, the valuation backdrop is alarming. Goldman Sachs data show South Korean equities (EWY) now account for roughly 14% of all global equity ETFExchange-Traded Fund - a basket of securities trading like a single stock. volume, and semiconductor stocks are trading at overbought levels (RSIRelative Strength Index - momentum oscillator on a 0-100 scale. 85-90 on weekly charts) not seen since the March 2000 dot-com peak.

The narrative has two camps. Bulls cite "AI memory demand is still in early stages, supply shortages expected for years," and point to Samsung's manufacturing expansions and wafer ramp targets (TSM targeting 180K 3nm wafers/month by year-end) as proof of durable demand. Bears counter that circular capital expenditure (NVDA investing in CoreWeave and other infrastructure plays to validate its own chip sales) creates an echo-chamber effect: if AI chatbots underdeliver on ROI, capex will collapse faster than it rose. Additionally, the concentration of gains in a handful of stocks (NVDA, MU, SNDK) while broader market breadth deteriorates suggests momentumThe empirical fact that winners keep winning over the medium term.-driven buying rather than fundamental repricing.

The risk scenario involves a capex recession if generative AI productivity gains disappoint enterprise customers. Insiders at chip makers have been cautious on outlooks, and some software names (EPAM, CSGP, premium SaaS) have cratered 40-60% YTD as investors repriced high-growth valuations downward. If this repricing spreads to chips, inverse ETFs like SOXS could see violent rallies. Traders are watching earnings calls closely for management commentary on AI server sales pipelines and customer commitment lengths. A miss or guide-down would be the narrative flip. For now, momentumThe empirical fact that winners keep winning over the medium term. remains bullish, but the risk-reward is increasingly skewed to the downside for new buyers.
