Each one teach one right? Well, Vanguard settlement funds...
TL;DR - make sure your dividends are actually being reinvested into your mutual fund vs sitting in a money market settlement account. So, longer story, at Vanguard you have a settlement fund that is used to hold your money when you are about to buy stock, after you've sold stock and then also apparently for dividends paid out. You can specifically request (select) to have your dividends reinvested AND your capital gains reinvested. I suppose there are reasons not to reinvest the cash that is generated but that should be a conscious choice not an "ooops...I should have selected that button". In my case that cash has been sitting around like it's in a savings account and not even a high yield one!!! Now I know better so I will do better - and if YOU* didn't know, now you do too. *I bet I'm going to come across a video I haven't watched yet that covers this exact topic....sorry in advance Twins.
