Despite the fact that your options are limited to what you plan provider offers, 401k plans can also include:
Individual bonds (corporate and government)
Certificates of deposits (CDs)
Exchange-traded funds (ETFs)
To put it simple, you can’t invest in physical gold bullion through a 401(k) plan. Buying stocks in gold mining companies or mutual fund that includes mining company stocks is the easiest method to invest in gold through a 401(k). We can name this method as purchasing “paper gold”. You will also find ETFs (GLD) and mining ETFs, which offer indirect access to investing.
