Okay, so when I first started reading MMM I got super excited and started a taxable investment account and put it in VSMGX. After learning some more, I'm focusing most of my savings on my 401k and IRA, so going forward I won't be adding a lot to that account, maybe $100 or so a month, but I want to change the funds to something more aggressive, either a total market index like VTSMX or a dividend focused fund like VHDYX. I'm not quite ready to pull the trigger, but I was playing around with the "exchange" button and it asks me what my Cost Basis method is.
"Vanguard offers the following cost basis methods for mutual funds: average cost (AvgCost), specific identification (SpecID), and first in, first out (FIFO). Our default method for mutual funds is average cost."
Now, the current value of my investment is almost the same as what it was when I put it in. Tiny loss, I'm sort of waiting to see if it will hit even, then make the trade. Regardless, any gain or loss is pretty small, and my plan for going forward is to set it and forget it. So I don't know if it really makes a difference, but is there a best system to use?
I'm sorry if this is a stupid question, I just want to make sure to not screw up too much.
