At this time, SoFi offers the ability to invest in stocks and ETFs.
We do not currently offer trading for mutual funds, which would include target-date funds.
For diversified portfolio options, check out SoFi Invest Automated accounts. Automated Investing offers automated financial planning driven by algorithms with no SoFi management fee. That means little or no direct human effort is needed.
