STMicroelectronics slips again as the sell signal reaches week 6

August 21, 2026

Our view last week

After last week's 7.1% rebound, STMicroelectronics stock is back on the back foot: this week the stock loses 3.2% with 84% of volume on the sell side, and the Sell signal, now under management for weeks, pushes the short above 12% in profit. The trend is losing conviction - ADX has fallen for the fourth straight week - while price stays boxed between a resistance and a support just a step apart.

This week's summary

STMicroelectronics, listed on the New York Stock Exchange, remains in a mature decline. The sell signal is in its 6th week and the short is already up more than 18%, but the weekly picture shows signs of fatigue: the trend has been losing conviction for six weeks, and the lower lows now come with a possible slowdown in momentum. Our model flags high risk for a new opening: we'd rather watch than chase.
