Industries' Descriptions

@Semiconductors (+3.09% weekly)

The semiconductor industry manufacturers all chip-related products, including research and development. These chips are used in innumerable electronic devices, including computers, cell phones, smartphones, and GPSs. Intel Corporation, NVIDIA Corp., and Broadcomm are some of the prominent players in this industry. Semiconductor companies usually tend to do well during periods of healthy economic growth, thereby inducing further research and development in the industry – which in turn augurs well for productivity and growth in the economy. In the near future, demand for semiconductor products (and possibly innovation within the segment) should only expand further, with the proliferation of 5G, autonomous vehicles, IoT, and various AI-driven electronics set to herald a new, advanced chapter in the technology-driven world as we know it. With burgeoning prospects comes great competition. In 2015, SIA estimated that U.S. semiconductor industry ranks as the second most competitive U.S. industry out of 2882 U.S. industries designated manufacturers by the U.S. Census Bureau.

@Electronic Production Equipment (+3.25% weekly)

The electronic production equipment industry makes equipment used to produce semiconductors. Such equipment includes wafer fabrication, plasma etching and photo-resist processing equipment. The industry also makes chemical vapor deposition processing systems and photomasks, which are high-purity quartz plates that contain patterns to define integrated circuits layouts. Applied Materials, Inc., Lam Research Corporation, and KLA-Tencor Corporation are examples of electronic production equipment manufacturing companies.
