STMicroelectronics stock among the strongest gainers on the CAC 40, +8.5% in one week
After occupying the bottom of the CAC 40 the previous day, STMicroelectronics reverses the trend this Friday morning and ranks among the best performers on the Parisian index. The semiconductor manufacturer is regaining ground in a broadly stable European market, as the CAC 40 edges up during the session.
A rebound that brings the stock back to its 50-day moving average
STMicroelectronics gains 2.67% to €46.08 mid-morning, recovering ground after Thursday's decline. The stock had found itself at the bottom of the CAC 40 in the previous session, but it rebounds today in contact with its 50-day MA at €46.04, with a near-zero difference of +0.09%. This level is now the central pivot of the configuration: as long as the stock maintains itself there, the upward momentum initiated since last week remains intact. Over a week, the gain reaches 8.58%, extending a rebound that had already been welcomed during Monday and Tuesday's sessions.
The RSI at 49 remains neutral, with no particular signal in either direction. The 20-day MA at €43.98, well below the current price (gap of +4.77%), now functions as a solid support cushion in case of a pullback. The support at €41.74 is more distant, and the resistance at €49.06 represents the next level to break through to confirm the continuation of the move.
A favourable sector context despite persistent macro uncertainties
STMicroelectronics' rebound is part of a positive momentum for semiconductors this morning. Among European peers, ASML Holding advances 2.09% and ASM International gains 1.63%. In the United States, Advanced Micro Devices gained 2.38% at Thursday's close, while Micron Technology gained 0.81%, in a sector globally well-oriented despite a slight decline in Nvidia (-0.41%). Over three months, the stock remains under pressure with a decline of 27.27%, a legacy of a pronounced correction since summer.
Second quarter 2026 results had revealed disappointing profitability despite revenue beating expectations, which continues to weigh on medium-term sentiment. The macro context remains charged: the dollar holds near a two-month high and money markets are pricing in an increased probability of a further Fed rate hike in October, which puts pressure on valuations of growth stocks. According to the consensus of surveyed analysts, the stock trades at approximately 20.3 times expected earnings for the following fiscal year, a multiple that reflects persistent questions about the group's earnings trajectory. The resistance at €49.06 remains the benchmark to watch to gauge the strength of this rebound.
