Thank you, MDM and Dodge. The 80/20 mix appeals to me because I am just starting to save and I imagine I won't have enough savings to retire for at LEAST 15 years, so it would make sense to take more risk now, right? Thanks for the links!
I've heard that MMM recommends VTSAX - the Vanguard Total Stock Index Fund, Admiral Shares; but it requires a $10,000 investment. I am scrambling to round up $5500 to open and max out an IRA fund for 2014. Why does MMM think the "Admiral Shares" fund is better than the Vanguard LifeStrategy Growth Fund (VASGX)? If I wanted to switch the money from my VASGX fund into a VTSAX fund at a later time, could I?
