If you have 3 tranches in them, you shouldn’t add any to them. If you don’t have a 3rd tranche in them, then you could add a tranche to CHL, CAJ and KHC and should probably let E pull back a bit before averaging down.
But what you don’t want to do is overweight certain positions by having a higher dollar amount in them, when fully invested.
So, I don’t have enough info to go off of because I don’t fully know your situation. But the above scenarios should give more clarity. Hope that helps.
