On Tuesday, the semiconductor sector experienced widespread declines, with ARM Holdings (ARM.US) dropping more than 6%. Advanced Micro Devices (AMD.US) fell over 4%, Intel (INTC.US) declined 4%, while Taiwan Semiconductor Manufacturing (TSM.US) and ASML Holding NV (ASML.US) both lost more than 3%. NVIDIA (NVDA.US) decreased nearly 3%, and Qualcomm (QCOM.US) slid over 2%.

According to FactSet data, the iShares Semiconductor ETF currently trades at a forward P/E ratio near 26 times, significantly above its 10-year average of approximately 19 times. The ETF now commands a 17% premium to the S&P 500 index, whereas historically it has typically traded at a slight discount to the broader market. Analysts suggest current market pricing appears to reflect near-perfect conditions. Interactive Brokers chief strategist Steve Sosnick warned that the primary risk lies in overly optimistic market expectations, with corporate earnings potentially struggling to consistently exceed forecasts.
