Some fun context...
Equities as a whole have been shown to grow consistently at around 7.1% after inflation (more specifically, 6.8% to 7.3% over all rolling 40 year periods). So we can anchor the DOW to this 7.1% real return mean linear line over a LONG horizon. In 1, 5, 10, 15, or 20 year spurts it can do much different things, but over 40, 60, 75, 100 years it sits at 7.1%...
So how does that project onto the 14,000 DOW from 2007 vs the 25,000 today... $14,000 in November 2007 becomes $16,430 in Nov 2017 dollars.
So in 2017 dollars we see the 2007 DOW as $16,430... now applying this 7.1% LONG term linear line (the regression gravity of our market)... we can say that the 2007 peak of $16,430 (today's dollars) is $32,629 today.
We still have a little ways to go if we're going to get to the exuberance experienced in 2007. 30% more to go in fact. Of course, the market doesn't work so nicely. The bottom can fall out anytime between now and then... or it might fall out after then. If you get that part figured out, please let me know
And we'll dance around it in the mean time. I've spent a great deal of time trying to decipher exactly where that median (100 year) line SHOULD be today... I keep coming up with a number like 18,000. We'll regress eventually... through flat years or pull backs. And spend equal time above and below it in the long run, as it grows at 7.1% every year
I do suspect the 7.1% will continue for the long haul, but I can't say for sure.
Every decade the market tends to double... at least on a LONG horizon. This is why the number 100,000 by 2050 is thrown out there. Makes your eyes pop, huh?
