While your statistics are not false they don't show a true picture of things. As with all statistics they are meant to generalize things so to give one a clear picture of reality. Lots of times the statistics are true but they show a picture that is not. What you have done is averaged a long term trend with a short term event, the precipitous drop in the market we had in the last few months. You could have done the same thing after the market dropped 25% in 1987. By averaging the long term average with our extreme drop over the last few months it makes it look like there were no gains in forty years. If you had stopped your statistics in 2007 you would have had a completely different picture. You would have a lot different picture if you had statistics from 1966 to 2016. It's like this. If you averaged Bill Gates' and my wealth we would both be billionaires. Unfortunately for me that isn't really a true picture of my financial situation. What's that saying about lies, damn lies, and statistics? Make real sure you know what you are doing with them because they can really confuse you if you don't.
