As I’ve been learning about how to become a DIY investor, I’ve been contributing to the Target Retirement 2050 Fund (VFIFX). I just contributed 3,000 this month. Is it a bad idea to invest in this fund right now whose NAV is 36.81 USD per share? It seems its value is at an all-time high. What if the price drops? Also, is this an okay fund to contribute to when your at the age of 33?
