Speak to a financial advisor (a fiduciary). One consideration is whether you’ll need cash in the near term (<5 years).

The other is whether you have expensive debt, like credit cards.

Dollar cost averaging might be a way to reduce risk a little bit (deciding on a regular amount / interval and sticking to that whatever happens.)

Finally, do you have an adequate safety net? (6m - 1yr of expenses in an insured account.)
