My answer to this current market situation is what it always is...
...it depends on your closeness to retirement mainly and then some other extreme things could change what you do now.
Example of an extreme thing...you just inherited 2 million dollars. If that's your situation, then you have a lot of things you could do.
But, for the average investor with no extreme things on the horizon, continuing to invest in the market if you are not yet retired is the way to go.
Within 10 years, if you want to put in a little extra at any time for any reason, it's not a bad idea. Once you get within 5 years, you might want to be a bit more conservative with putting in extra, but again, that depends on your situation.
In any event, you should make sure that by the time you retire you:
1) Are debt free including owning your home outright.
2) You either have 30% or more in bonds, OR you are 100% invested in stocks with at least 3 YEARS of expenses saved in a liquid way.
A married couple who had even halfway decent jobs, if they retire debt free and own their home outright and have no extreme situations, can live on Social Security income taken at age 65. Any extra money from investments is just gravy.
BUT, or course if you don't want to rely on SS or want to have a GOOD retirement or want to retire earlier than age 65, then investing is key.
