StocksSTMicroelectronics N.V
STM (STMicroelectronics N.V) is a US-listed company; equity CFDs let you trade its price moves. STMicroelectronics NV is a European multinational semiconductor contract manufacturing and design company. It is the largest of such companies in Europe. The company is incorporated in the Netherlands and headquartered in Plan-les-Ouates, Switzerland. It manufactures a wide range of microelectronics, including the widely-used STM8 and STM32 microcontrollers. ST was founded in 1987 from the merger of two state-owned semiconductor corporations, SGS Microelettronica of Italy and Thomson Semiconducteurs of France, with the aim of creating a corporation that could compete effectively with international semiconductor manufacturers. From early on, the company's senior management sought out poorly-served niches in the global market, such as microcontrollers, application-specific integrated circuits and analogue chips, and pursued vertical integration of its manufacturing. Sector: Technology (Semiconductors); founded 1987; headquartered in Netherlands; CEO Jean-Marc Chery. Individual names are driven by fundamentals, sector cycles and the broad market, with elevated volatility around earnings. Sessions (ET): Monday–Friday 09:30–16:00, closed on weekends and US holidays; CFD quoting runs about 09:35–15:55 ET (no pre/post-market — broker-dependent).
