If you want to play the market, you'll take risks. If you've got a couple months timeframe, it may be a good time to begin your entries. If you've got a couple years, I'm really not sure if I have advice for you. All I should say is that it will bounce back and sometime before 2024, the stock market will be higher than it is today. And I can only 99% be sure of that much.
I usually try not to tell you what to do -- too crowded there. I'll point out what price points/trends/patterns the pros are looking at and let you interpret what that means for your portfolio.
