If you're not living off of dividends, be sure you have DRIP enabled for your taxable portfolio (and your 401k, I suppose. But that should already be set).
The latest numbers are really pointing to a dive and we've already been seeing daily dips in the market that no one in politics are talking about.
At the very least, take automatic advantage of this chance and buy when you get paid that dividend. Yes, you'll still pay taxes but at least you'll also be DCA'ing
