Taiwan Semiconductor Manufacturing Co. Ltd. (NYSE:TSM) stock rose nearly 1% in premarket trading Tuesday as semiconductor stocks extended their rebound amid improving risk sentiment and renewed investor appetite for large-cap technology shares.
Nasdaq futures gained 0.77%, while S&P 500 futures advanced 0.44%. The iShares PHLX Semiconductor ETF (NASDAQ:SOXX) climbed more than 2%.
The world’s largest contract chipmaker continues to benefit from surging demand for artificial intelligence infrastructure, helping cement its position among the world’s most valuable companies.
Taiwan Semiconductor Enters Global Top 10
Taiwan Semiconductor ranked ninth among the world’s 100 most valuable companies after its market capitalization jumped 101% year over year to $1.427 trillion as of March 31, according to a report from PwC Taiwan.
The gain lifted the company from 12th place a year earlier and made it the fastest-growing company within the global top 10. Taiwan Semiconductor was also the only Taiwanese company to make the list, the Taipei Times reported on Tuesday.
Its rise helped propel Taiwan from seventh to fourth among economies represented in the rankings, trailing only the United States, China and Saudi Arabia.
PwC Says AI Demand Boosted Taiwan Semiconductor, But Risks Remain
PwC Taiwan chief markets officer Lin Yi-fan noted that strong demand for AI devices and semiconductors doubled Taiwan Semiconductor’s market value, highlighting Taiwan’s crucial role in the global technology supply chain.
Lin also warned that Taiwan’s heavy reliance on a single industry creates risk.
He said semiconductor and AI supply chains remain key growth drivers, but long-term market-value growth could be pressured by swings in the semiconductor cycle, underscoring the importance of industrial diversification.
The top 10 companies by market capitalization were NVIDIA Corporation (NASDAQ:NVDA), Apple Inc. (NASDAQ:AAPL), Alphabet Inc. (NASDAQ:GOOGL), Microsoft Corporation (NASDAQ:MSFT), Amazon.com, Inc. (NASDAQ:AMZN), Saudi Arabian Oil Company (Saudi Aramco), Broadcom Inc. (NASDAQ:AVGO), Meta Platforms, Inc. (NASDAQ:META), Taiwan Semiconductor and Tesla, Inc. (NASDAQ:TSLA).
Technical Analysis
TSM remains in a clear longer-term uptrend: it is trading 3.6% above its 20-day SMA ($415.49), 10.1% above its 50-day SMA ($391.04), and 31.5% above its 200-day SMA ($327.29), which keeps the primary trend bias pointed higher.
The 20-day SMA is above the 50-day SMA, and the stock is still benefiting from the golden cross that formed in June 2025 (50-day SMA above the 200-day SMA).
Momentum is the one area that looks less “clean” right now: MACD is below its signal line and the histogram is negative, which suggests upside pressure is cooling versus the prior upswing.
In plain terms, when MACD sits below its signal line, it often means the trend can keep rising, but it may need consolidation or a fresh catalyst to restart stronger momentum.
From a structure standpoint, the stock is still working below its 52-week high ($450.16) set in June, so that zone is the obvious upside reference if buyers keep pressing.
On the downside, the March swing low remains the most important “line in the sand” area on the chart, because a break of that type of pivot often changes the intermediate trend conversation.
- Key Support: $385.00 — a nearby level where buyers previously stepped in, and it sits close to the broader trend area around the 50-day moving average zone
