<prompt> Human: I feel so uneducated. I cannot understand the lingo. Ive Googled it all and it hasnt helped. All Im trying to determine is whether or not my Roth IRA mutual fund is a good read: successful one. VGSTX Vanguard STAR FundYou can give me a yes or no, but please explain what numbers I can look atfor to determine if a fund is good or not. I want the answer, but I also want to learn.P. S. Please be nice. Ive been contributing to this fund for almost 10 years now so itd be heartbreaking to discover it sucks...  <response>: The Vanguard STAR fund is a fine fund. But it would be more appropriate to have your Roth IRA invested in one of Vanguards target retirement funds that will be better balanced for your goal retirement date, and somewhat cheaper than the STAR fund to own. The STAR fund would generally be considered too conservative for someone in their 20s, but too aggressive for someone in their 50s. A target fund will automatically rebalance for you as you age.
