I say this because it has recovered all of what it lost during the crash earlier this year.

The Federal Reserve made this possible with money supply manipulation, but the underlying economy is still quite fragile from the pandemic.

Vanguard's money market fund VUSXX is where your nest egg belongs.

This is a constant value fund, meaning it doesn't fluctuate.

Therefore, it is a good core holding from which to deploy portions of it over the next five to seven years into suitable retirement holdings.

By suitable retirement holdings, I mean mutual funds or exchange traded funds whose portfolios consist mainly of BBB+ bonds and which pay a monthly dividend.

If you're not already in a tax-deferred IRA type account but you still have earned income, it might be a good idea to open one for any new money you want to add between now and retirement.

Municipal bond funds are a place to eventually deploy *some* of your VUSXX nest egg, since their dividends are typically exempt from federal income tax. Just remember that state and local tax collections are vulnerable to a fragile economy as well.
