Investing in exchange-traded funds (ETFs) is a smart decision for a variety of reasons. They create instant diversification, limiting your risk. They're also passively managed, making them less expensive than their actively managed counterparts.
Choosing the right ETF, however, can sometimes be a challenge. With seemingly limitless funds to choose from, it can be difficult to determine which one is the best fit for your situation.
Two of the most popular ETFs are the Invesco QQQ ETF (NASDAQ: QQQ) and the Vanguard S&P 500 ETF (NYSEMKT: VOO). There are advantages and disadvantages to both of these funds, so here's how to decide which one is the better buy.
