]Did you look at the article I linked to and see the chart of the inflation-adjusted DJIA? From 1916-1994, the market was NOT linear.
I did look. Here is the chart from that article:
And here's the amount of money the FED printed :
Do these look similar to you?
Neither chart is linear, but the relation of debt to market valuation is linear.
The FED prints money, the markets move up.
Why isn't 1916 to 1970 like the period after it?
Because during that first period the FED wasn't allowed to freely print money. Note how things moved more smoothly before 1970!!!
Because before 1970 their ponzi scheme was not running yet.In addition, I mentioned that the components of the Dow get changed and that also affects things. Poorly-performing companies get dumped from it, good ones get added. I'm not sure how a broader index, i.e., one with way more than 30 stocks, would look as far as your hypothesis goes, but I'd be curious and I think it'd be a better test.
That's not how the Dow works. They don't kick out poorly performing companies due to PRICE, they substitute LOW VOLUME companies.
If GE stocks move 200 billion a day and crash 90%, GE would still be listed.
The Dow represents the stocks that matter the most (in the opinion of the Dow Jones methodology), not the best performing ones. The intention of this index is precisely to show how the American industrial output is doing on the market.
Also, you're saying that the slope of the index (price vs. time) is the % gain. That doesn't seem right simply from a unit analysis [slope = d(price)/d(time)], whereas % gain is p2/(p2-p1)*100 . You'd have to do linear regression to get a curve and then take the derivative of that--and the result isn't the percentage gain. Maybe someone with a stronger background in math could give some input here.
You're overcomplicating things.
My point about the slope is that you mentioned the inflation adjusted chart.
Note that the chart you posted goes back before the time when the FED could freely print money so you clearly have two periods there: from early 1900's when there was real capitalism and then after 1970 when the FED started controlling the markets by freely printing money for their banking pals.
