PSI tracks a benchmark that is designed to provide returns based on various investment criteria of semiconductor firms. Semiconductor chips act as the brains to numerous devices that we rely on today, including smartphones, calculators, computers, and much more. As technology continues to improve and expand, these chips will invariably be in demand to help power new devices. The fund focuses entirely on U.S. stocks, giving investors pure domestic exposure to numerous semiconductor producers. Investors should note that this fund dedicates the majority of its assets to medium and small cap funds, meaning that it will be more volatile than a traditional large cap fund, but it also presents strong growth opportunities for those who believe in the semiconductor segment of our nation.
