Video:Bogleheads® investment philosophy

main article: Bogleheads Investment Philosophy

The Bogleheads follow a small number of simple investment principles that have been shown over time to produce the best results. These ideas come from the investing philosophy of Vanguard-founder Jack Bogle. Some of these ideas are distilled from Nobel prize-winning financial economics research on topics like Modern Portfolio Theory and the Capital Asset Pricing Model. But they are really very easy to understand and to implement, and they work. In fact, the basis of all of these principles is the idea that successful investing is not a complicated process, and can be accomplished by anyone with a small amount of effort.

This wiki introduces these principles with short entertaining video segments to give investors the big picture and an orientation to the more detailed discussions on this wiki site and in the recommended books.
