Taiwan Semiconductor: sell signal stalls out, trade down 5%

August 21, 2026

Our view last week

Taiwan Semiconductor stock loses steam on the way up: after last week's 3.9% rebound, the stock climbs only 1.5% this week, and buyers fall to 52% of volume, down from 78%. Price is back at the 20-day trigger level, inside the no-trade zone, while a sequence of 3 higher lows on the daily chart (373 area toward 408) sketches a base not yet confirmed. The Sell signal is in its 5th week: the decline is losing momentum, but the trade still sits at a 7% loss.

This week's summary

The Taiwan Semiconductor sell signal reaches its 6th week and has never confirmed: price climbed back up over the three observation weeks instead of falling, and the trade still sits at a 5% loss. The weekly picture stays bearish under our parameters, but the decline has lost momentum, with ADX falling for 6 weeks and volumes contracting. Our model advises against new entries: better to wait for clarity before acting.
