Will Index Funds such as VOO/VTI truly continue to increase forever? I am currently 24, just started investing about 2 months ago. I have like 25,800 into VTI/VXUS right now, with a 90/10 allocation. I am just having trouble understanding that all you really have to do is invest in “safe” ETF’s, and you will increase. The market has gone up today, is it safe to assume that VTI prices will be at around 2000 in 40 years, from 283 today?
