It isn't meant for investors looking to find the next hot stock. It is designed for investors who recognize the difficulty of that goal. Here's why long-term investors might want to consider adding a broad-based ETF like this to their portfolio. You'll own everything Vanguard Total Stock Market Index ETF basically owns all of the stocks that trade in the U.S. market. It uses a market-cap-weighted approach, so the largest companies have the greatest impact on performance. That's basically how the economy works, so this weighting methodology makes sense. Right now, some of the biggest holdings are the names you would expect, including Nvidia, Apple, Microsoft, Amazon, and Alphabet. Image source: Getty Images. However, the expansive stock exposure means you'll own whatever hot stocks are leading the market at any given time. There's no need for you to try to pick and choose the winners, as they change over time. They're in the portfolio already. The key benefit is that your performance will be exactly in line with the market because you own the market.
