Nowadays, almost anything can connect to the internet. From light bulbs and traffic lights to cars, TVs, refrigerators, sensor-pocked oil pipelines and the smart speaker in your home, it's become difficult to walk 20 feet without bumping into the Internet of Things (IoT).
Size and scale makes investing in the Internet of Things complicated. Too many companies do something to make the IoT what it is, and yet buying every stock with an IoT story isn't an option for most investors. What to do? The simplest and potentially safest route could be to invest in the biggest IoT stocks -- large-cap companies with well-defined IoT business units that will grow as the movement grows.
