4 Best Semiconductor Stocks to Buy Now We know all about the chip shortages, and if you haven't sunk some money into a semiconductor stock, your FOMO could be real. Let's dive into four semiconductor stocks to...

So, electronic devices saw unprecedented upheaval as soon as the COVID-19 reared its ugly head. A combination of record demand in many sectors (automobiles, consumer electronics, and more) threw supply chain issues as a major wrench into the mix.

Companies and consumers use semiconductors, which are small conductors of electricity called semis or chips, and they go into thousands of types of devices — think cars, smartphones, appliances, machinery in medicine, and more. Companies across the world work to make semiconductors more streamlined and powerful.

• Microprocessors: A microprocessor is a component that performs the instructions and tasks that occur in computer processing. It contains arithmetic, logic, and control circuitry.
• Memory chips: Memory chips store data or process code through an integrated circuit through the use of millions of capacitors and transistors.
• Commodity integrated circuits: Simple chips like commodity integrated circuits are used to perform repetitive processing routines, typically in single-purpose appliances like barcode scanners.

You'll find an endless variety of trading and investment opportunities in semiconductor stocks, and semiconductor ETFs also offer a great way to gain exposure to the sector.
