My 401K provider doesn't have an auto allocation option. I am aiming for mildly aggressive as I am almost 30 with a decent income (between 100-150K). I have realized that 100% of my investments were going to T Rowe Blend 2060. It did ok this year, but I would like to know if I can do better. I did some of my own research and landed on these options. Granted this has only been 10-15 minutes of skimming reddit, so I'm curious if this is diverse enough or too aggressive.
