STMicroelectronics Shares Drop Nearly 7% in a Week, Key Support Threatened
STMicroelectronics ended the week on a negative note, dropping 2.48% to 27.11 euros this Friday, March 20. The semiconductor manufacturer's stock has seen a decline of 6.94% over the last seven days amid heightened tensions in European markets. Meanwhile, the CAC 40 also fell by 1.40% during the session, to 7,698 points.
Technical Analysis: Current Trends and Indicators
The share price of STMicroelectronics has fallen below its 20-day moving average, set at 28.50 euros, confirming the exhaustion of the bullish momentum observed since the beginning of the year. However, the stock still remains above its 50-day moving average (26.63 euros) and well above the 200-day average (24.14 euros), indicating a medium-term trend that is still oriented upwards: the three-month performance is at +22.23%. The RSI, an indicator measuring the relative strength of the movement, is at 47, which is in the neutral zone, without any oversold signal. The price is approaching the lower boundary of the Bollinger Bands (27.17 euros), a technical threshold that, if breached, could lead to a test of the support identified at 24.61 euros. On the upside, the nearest resistance is at 29.38 euros. In the European semiconductor sector, ASML Holding also fell by 2.16% during the session, illustrating a selling pressure common across the industry.
Market Sentiment: Caution Prevails in European Trading
Today's session was marked by a general climate of caution across European markets. The SBF 120 lost 1.39% during the session, while the VIX, a barometer of implied market volatility in the U.S., stood at 25.09 points at its last available quote (March 18), a level indicating high tension, up more than 12% from the previous day. For STMicroelectronics, the next major appointment is set for April 23 with the publication of the first quarter 2026 results. This deadline could be an important catalyst, likely to provide increased visibility on the evolution of demand in the automotive, industrial, and consumer markets, key segments for the Franco-Italian group listed in Paris and Amsterdam. The stock's beta, measured at -0.30, indicates an inverse and moderate correlation with its reference index over the recent period, an atypical statistical profile that may reflect the unique dynamics of the semiconductor cycle. The monthly volatility, at 11.43%, remains contained compared to the movements observed over the past week.
