Nvidia (NASDAQ: NVDA) has been one of the best-performing stocks over the past five years, creating a lot of millionaires in the process. However, with those strong returns in its rear-view mirror, investors today might be better served to look instead for the next set of potential huge winners.

Nvidia (NASDAQ: NVDA) has been the stock everyone is talking about for quite some time -- and for good reason. The company dominates the artificial intelligence (AI) chip niche with a market share of about 80%, and this has translated into record earnings. Even better, Nvidia's focus on innovation means its dominance is likely to last.

That's exactly what has happened with Nvidia. Over the past year, Nvidia stock is up by 166% as the surge in AI investment has been a massive tailwind to the business. On the other hand, even including its massive dividend yield, the YieldMax NVDA Option Income Strategy ETF is up by about 105%. That's 61 percentage points of underperformance.

If you want to earn a big return and turn $25,000 into more than $1 million, there is a safer and better way to do so -- assuming that you're willing to be patient. An exchange-traded fund (ETF) can allow you to generate some massive gains over the years,

Tesla (TSLA) and Nvidia (NVDA) stocks have done well in the past few days as American equities bounced back. Tesla has jumped by over 33% from its lowest point in August and is slowly nearing its highest point this year.
