Another View on Taiwan Semiconductor Manufacturing’s Valuation

The narrative DCF work suggests Taiwan Semiconductor Manufacturing is about 10.2% overvalued at $420.04 compared with a $381 fair value. By contrast, our P/E based view shows a different angle. TSM trades at 27.7x earnings versus a 50.9x industry average and a 61.3x peer average, while the fair ratio is 43.7x.
