If your employer offers a 401(k) plan, you will be offered a menu of investment choices, typically mutual funds (stock funds and bond funds). You will want to have a mix of funds that matches your risk tolerance and savings goals.
If you are using Icon, you will be automatically enrolled into a target-date fund that adjusts automatically over time. This type of fund helps make sure you have a mix of investments that matches your risk tolerance and savings goals.
With Icon you can also build your own portfolio by selecting from a menu of investment options.
