Posted this research to another board I frequent and thought some here might get some use out of it since stocks/equities are a part of everyone's investments on some level (at least I would hope)...
So I found the following link which displays the yearly dividend adjusted S&P500 returns for the last 140 years.:
CAGR of the Stock Market: Annualized Returns of the S&P 500
The link at the bottom shows where the data came from:

Conclusions:
There are a lot of reasons to think that the next 10 years are going to be gloomy... with all that is going on in this country right now. However, historically speaking... the next 10 years 'should' average a 9-13% CAGR above inflation (12-17% actual return) if history really repeats itself... History also shows that the longer this near 0% market return continues (currently we're at about 12 years) the larger the pop on the other side will be. I'm guessing the late teens and early 20's are going to have some very bullish years similar to what we saw in the mid 90s.
I'll look closer at the 5, 7, 15, 20 periods that look similar to the one we're currently in and see if they tell the same kind of story.
