"1) You can predict the future by running statistical analysis of the past."
Not exactly predict the future, but stocks do have a tendency to repeat paterns.
"2) Stocks have always been out performing bonds, real estate, and cash."
In the long term there is some truth to this. In any given period of 1 day to ten years, your mileage may vary.
"3) You should start investing early in stocks (and mutual funds) rather than paying off your mortgage and loans."
Yeah I'm sure brokers and MF companies are guilty of pushing this. That said, nothing wrong with investing early if you can pay loans off as well.
"4) Timing the market doesn't make much of a difference, investing a fixed percentage of your income for the long term regardless of market condition would guarantee a good return."
Hey - this one bugs me a lot. I think an individual can do both. Especially if you actually invest (BUY!) MORE when the market is down. But steadiness can be a winner. Look who came out the best in this last dive. People who saved a LOT and people who timed OUT before the dive.
"5) No one can beat the market in the long term."
"No one" - that excludes a lot of people!
