Is this a good time to invest?

It is impossible to time the market, so it doesn't really make sense to answer this in absolute terms. Is it a better time to invest than last month? Yes. Than last year? Yes. Could it be even better to invest next quarter? Possibly. But this is a unique situation and the markets are forward looking, so it is difficult to say.

The safest thing to do is average into it. Say you have a target to invest $2K/month under "normal" conditions. On a really bad month, maybe make it $4K. If conditions worsen next month, increase your investment even more. Eventually you might not be able to stand it...

From technical perspective wait until markets retest the bottom. They will.

There would be a lot of distressed assets after it is over. Lots of opportunities, so conserve cash.
