STMicroelectronics Stock: 14.68% Drop Over the Week Following Earnings Warning
STMicroelectronics experienced a particularly challenging week on the Paris market. From Monday, October 20 to the close on Friday, October 24, the semiconductor manufacturer's stock fell by 14.68%, closing at 21.56 euros. This correction occurred despite a generally favorable stock market environment, with the CAC 40 gaining 0.45% over the same period.
Sharp Decline Focused on Thursday's Trading Session
The sharp decline was concentrated on the trading session of Thursday, October 23, where the stock plummeted by 14.12% in a single day, dropping from 25.49 euros to 21.89 euros. This drastic fall was due to the publication of the third quarter 2025 results and particularly due to the disappointing outlook. The company mentioned a slow and uncertain recovery in its activities, fueling fears about its recovery trajectory. Trading volumes surged that day, with over 9.4 million shares traded, compared to 2 to 3 million on previous days, indicating a massive sell-off. Over the past year, STMicroelectronics has now declined by 17.18%, highlighting the persistent difficulties of the semiconductor sector in an unfavorable market cycle. Financial analysts, however, maintain an average price target of 27.70 euros, representing a potential increase of 28% from current levels. UBS adjusted its recommendation on Friday, remaining optimistic about the stock despite the correction.
Technical Perspective Shows Bearish Short-Term Dynamics
From a technical standpoint, the stock is now significantly below its 50-day moving average, set at 23.61 euros, confirming a bearish dynamic in the short term. The 200-day moving average is at 23.11 euros, a level that the stock has also breached. The RSI indicator is at 34, indicating an oversold zone but not yet signaling an imminent turnaround. The MACD, slightly positive at 0.02, struggles to establish a clear trend following the sharp correction. The Bollinger Bands currently frame the price between 22.23 euros on the lower bound and 26.71 euros on the upper bound. The stock is trading close to the support level at 21.56 euros, while the first major resistance is positioned at 26.57 euros, the highest level reached at the beginning of the week. The one-month volatility stands at 18.12%, reflecting the magnitude of recent movements. A beta of 0.02 indicates a low historical correlation with the market, although the past week has shown a marked disconnection from the positive evolution of the Paris indices.
