If early retirement is something you’re striving for, you’re not alone. A 2024 YouGov survey found that 22% of Gen Zers and 30% of millennials expect to retire between the ages of 51 and 60. (1) That’s young, especially if you consider that Medicare eligibility typically doesn’t begin until age 65 and Social Security’s full retirement age for Gen Zers and millennials is 67.
If your goal is to retire early, you’ll need to save aggressively early on in your career and invest your money wisely. Finance personality Jim Cramer has some guidance in that regard.
He told CNBC (2) he has a “radical” approach to help everyday investors grow their portfolios and meet their financial goals. Here are the three assets Cramer says to invest in — and what you need to know about them.
Investing in index funds is a strategy many financial experts recommend.
Index funds are passively managed funds that aim to mirror the performance of a specific market benchmark. An S&P 500 index fund, for example, will seek to replicate the S&P 500’s performance by matching its holdings and weightings.
They differ from actively managed funds in that they don’t have professionals hand-picking stocks. An active fund will try to perform better than the S&P 500 by picking a handful of stocks from it. Conversely, rather than try to beat the market, an index fund is happy to capture its returns.
Investing legend Warren Buffett has long recommended that everyday investors put their long-term savings into index funds. And research supports this theory. Index funds tend to outperform the majority of fund managers tasked with picking stocks, especially when factoring in their lower fees.
For example, according to S&P Global, in the 15 years ending June 30, 2025, roughly 88% of actively managed large-cap funds underperformed the S&P 500 index. (3)
While some financial experts may recommend putting all or the bulk of your investment capital into index funds, Cramer says to keep them to about 45% to 50% of your portfolio.
His logic is that a large position in index funds can help anchor and diversify your portfolio. But branching out into other assets could make it possible to beat the market broadly and enjoy higher returns.
