TSMC Stock: Overvalued or poised for more gains?
15 Aug
Summary
- TSMC stock has seen a substantial 3.8x return over three years.
- AI chip demand and new factories may fuel growth.
- DCF valuation suggests shares are approximately 25.7% overvalued.

Taiwan Semiconductor Manufacturing has experienced a remarkable surge, returning 3.8 times its value over the past three years. This impressive performance intensifies scrutiny on whether current share prices still allow for substantial future gains. Demand for AI-related chips and ambitious capacity expansion, including a joint image sensor factory with Sony in Japan, bolster expectations for continued growth.
However, significant capital expenditure and execution risks associated with multiple new fabrication plants could strain future free cash flows. The stock's mixed value score of 3 out of 6 reflects this complex valuation picture. A Discounted Cash Flow analysis, based on a projected NT$1.1 billion free cash flow and assuming continued growth, suggests an intrinsic value of $339 per share.
This valuation falls below the current market price, indicating the stock may be approximately 25.7% overvalued from a cash flow perspective. The market's optimism might stem from anticipated long-term AI and automotive opportunities, which the cash flow model treats with more caution, especially given the substantial investments in projects like the NT$6.4 billion Japanese factory.
