I've always hear the market returns 10% / year and because of that I have investments that are long the market, but someone brought to my attention that this might not always be true.
1920 the DJIA was @ 110. The year is 2008, so that is 88 years. The rule of 70 is you take 70 / interest rate and you'll get the number of years it'll take for your money to double. So in this case you're money will double 12.5 times.
1) 100
2) 200
3) 400
4) 800
5) 1600
6) 3200
7) 6400
9) 12800
10) 25600
11) 50200
12) 100400
we're not anywhere close to DOW 100400!!
We've actually only doubled 9 times, so if you solve for interest rate you get 7.7%
so is the expected return really only 7.7%??
