I'm not sure this will resolve so quickly. Hopefully you're right, but I'm really not concerned with such a short term. Meanwhile, I guess one could "buy the dip" if they have a cash position they are willing to bet with. If the market dips lower, it might be a good time to convert some of your traditional IRA/401K to Roth, and pay taxes on a lower value. This of course means you have some confidence that the market will recover before you need the money. Obviously, everyone needs to "do the math" for themselves.
Also, to keep things in perspective, the market is only down about 5% YTD. The big gains in February failed to consider the potential impact of Trump's trade policy.
