5. Buy mutual funds
Mutual funds pool money from many investors to build a diversified portfolio of stocks, bonds, and other assets. They come in two main varieties. Passive index funds aim to match the performance of a benchmark like the S&P 500, while actively managed funds try to beat it by having managers select individual investments.
In practice, most actively managed funds don't outperform their benchmarks over the long term, and they carry higher fees. For most investors, low-cost passive index funds are the more reliable and cost-effective choice.
6. Invest in ETFs
Exchange-traded funds are similar to mutual funds but trade on stock exchanges like individual stocks, giving them greater liquidity. Most ETFs are index funds, designed to track the performance of a specific market index, sector, or asset class. The Vanguard S&P 500 ETF, for example, tracks the S&P 500 with low investment expenses and no meaningful minimum.
ETFs are an excellent choice for investors building a diversified portfolio from scratch or those who want broad market exposure without the complexity of picking individual securities.
7. Purchase I bonds
One interesting way to invest some of your $50,000 is through Series I savings bonds, commonly known as I bonds. I bonds are a special type of savings bond issued by the U.S. Treasury and designed to protect against inflation.
I bonds pay an interest rate that combines a fixed rate, which stays the same for the life of the bond, and an inflation-based adjustment, which resets every six months. The fixed rate for new bonds issued from November 2025 through April 2026 was 0.90%. Including the inflation adjustment, they guarantee a total annualized yield of 4.03% for at least the first six months.
The primary reason we suggest putting some of your money to work is that individual bond purchases are capped annually at $10,000 per person, one of the main drawbacks of investing in I bonds.
