TSMC Plummets 2.56% Amid Bullish Outlook and Bearish Sentiment: What’s Driving the Volatility?

Summary
• TSMC’s stock plunges 2.56% intraday to $283.17, a sharp reversal from its premarket 2% surge.
• The chipmaker raised its full-year revenue forecast to mid-30% growth, citing strong AI and smartphone demand.
• Institutional profit-taking and valuation concerns weigh on sentiment, with Guardcap Asset Management trimming its stake.
• The semiconductor sector faces mixed signals, as Intel (INTC) drops 3.9% and TSMC’s options chain shows aggressive short-term positioning.

TSMC’s volatile session reflects a tug-of-war between optimism over AI-driven demand and caution over valuation. With the stock trading near its 200-day average and a bearish MACD crossover, traders are bracing for a critical test of support at $284.86.

Bullish Earnings vs. Bearish Profit-Taking
TSMC’s intraday selloff stems from a collision of conflicting signals. On the bullish side, the company’s October sales surged 16.9% YoY, and it raised its full-year revenue forecast to mid-30% growth, driven by AI chip demand for Nvidia and smartphone processors for Apple. Analysts like Wedbush’s Matt Bryson reiterated outperform ratings, citing N3 capacity expansion as a catalyst. However, bearish forces emerged as institutional investors, including Guardcap Asset Management, reduced stakes, signaling profit-taking. Negative sentiment also amplified as analysts warned of a potential AI-sector pullback and rising capex costs. The stock’s sharp decline from its premarket high of $293.85 to an intraday low of $280.01 underscores the tug-of-war between optimism and caution.

Semiconductor Sector Under Pressure as Intel Slides 3.9%
The semiconductor sector faces headwinds as Intel (INTC) drops 3.9% intraday, reflecting broader concerns over valuation and macroeconomic risks. While TSMC’s AI-driven demand remains robust, the sector’s mixed performance highlights diverging investor sentiment. Intel’s struggles with its 18A process and competitive pressures from TSMC’s N3 node underscore the sector’s fragmentation. TSMC’s ability to outperform its peers hinges on its capacity to sustain AI and smartphone demand amid rising capital expenditures and geopolitical risks.
