So, mero company offers me certain percentage of match on 401K. So, I thought let me open one finally after 3 yrs. While I have been investing on Vanguard Institutional Index-Inst Plus (42.09%), Vanguard Total bond market index Inst (11.26%) and JpMc retirement 2050-C (46.65%). I have no idea what I'm doing and if I am doing it right and how this thing works :(

Any advice would be really appreciated.
