A,
Sell and implement one of the Couch Potato Building Block portfolios. That will get you out of trader/timer thinking. Even now your question is burdened with the liabilities of trader/timing thinking. It leads you to crystal ball questions that require making guesses about the future price of a particular asset class.
Human beings aren't very good at guessing the future, particularly those who tend to believe they can.
Once you establish a fully diversified portfolio the ONLY issue you'll face will be whether you have built one with a risk/volatility level that you can tolerate.
