This ETF is among the more unique exchange-traded products available to U.S. investors; it offers a way to invest in publicly-traded private equity firms. This sector of the market likely receives little allocation in most portfolios, and as such PSP can offer access to an asset class that most investors generally overlook. It should be noted that private equity firms can exhibit significant volatility, and the downside risks in unfavorable environments can be significant. However, the opportunity to gain indirect exposure to hundreds of private companies that may maintain promising growth characteristics has obvious appeal, and as such PSP may be worth a closer look for risk tolerant investors. There are some other similar options out there; BDCS, structured as an ETN, has some overlap but is different in several ways as well.
