<prompt> Human: Im investing 5,500 for 2017 and 4,500 for 2018. I do have emergency fund left over. I probably wont reinvest into this for at least a few years, but I wanted to put something in now. I chose Roth IRA because I have a low-paying job while in college, putting me at a low tax bracket. I chose Vanguard because of the low fees. Im debating with myself about how I want to allocate this. Ive read the sidebar and seen the guideline about my age as bonds, as well as 20 of stocks being international. Im risk-averse so allocating 80 to stocks worries me, but I understand that Im young and can take a hit, and I do trust the worlds economies and that wed survive any kind of recession... Or do I just select a target date fund set for my expected retirement date, and from my understanding it allocates appropriately for me?I dont have much help with this as neither of my parents has an IRA, and so Im second guessing myself and am kind of uncertain as I go through this process. Is there something else I should know?Edit: I realized that I went through here when I was starting my process, to open the IRA. Should I instead be going through here to open a target date fund? Edit 1.5: First link! Thanks.Edit2: Regarding my dividends and capital gains, should I reinvest those or transfer them to my money market settlement fund? Is there a difference? Edit 2.5: Chose to reinvest! Thanks.Edit3: Now time to invest the 10,000 somewhere. If I select from a list of Vanguards funds, and filter only for Target Retirement Funds, I believe that the two best options for me would be to invest in VTINX Target Retirement Income at an expense ratio of .13, or VLXVX Target Retirement 2065 at an expense ratio of .15... Though Im not sure the difference, or rather, which is best for me? I know that lower expense ratios are good, but 2065 hits the year that I would likely retire. Is it even the best option to choose from Vanguards available Target Retirement Funds, or would something else better suit my goals?  <response>: At 19 years old, risk aversion doesnt make much sense. Youre going to let it grow for the next 45 and not touch it until then. For example, if your average return is 5.5 a year instead of 6 due to high-risk aversion, you could be losing out on significant amounts of money by the end. Play with some compounding interest calculators to see how slight percentage differences impact your end total. Go for your actual target retirement year if you go that route.
