Currently, through my employer, I have Voya 401K and 457 plans. 100% of my investments (5% contribution to get the employer match in my 401K and 10% contribution in my 457) are elected to the State Street Target Retirement 2060. So far, I'm getting an okay return, almost 6%. I chose that fund because it seemed to be a good balance of US stocks, international stocks, and bonds, automatically adjusting the percentage balance between the three as I get older.
My goal is, eventually, early retirement/financial independence; I am 25.
Yet there are many, many more options that I want to learn about, but don't understand, e.g. Capital Preservation, Fixed Income, Moderate Allocation, Large Cap Domestic Equity, Mid/Small Cap Domestic Equity, International Equity, and Emerging Markets, with funds under each of them, including, just to name a few, State Street Bond Market Index, Dodge & Cox Stock Portfolio, and T. Rowe Price Mid Cap Value; I have no idea what any of this means.
What is the best way to learn about all of this so I have full control and understanding of my investment options? Is it simply a matter of clicking each fund and reading about them? Should I stick with one fund throughout the course of my working career or should I put a certain percentage into different funds that pertain to my goals? Thank you to anyone who can help!
