Myths and legends of asset allocation - A empirical study

Hello my fellow steemians!

For my studies of technical oriented business administration I have to write a paper about the theme "Myths and legends of asset allocation - A empirical study". So I would like to invite you to post here some Myths or legends you know about the asset market and support me with my studies.

I will be posting over the next couple of weeks how the paper develops and maybe we can do away with some myths or confirm them.

Stay tuned.

P.S: Due to the fact that there is no Stock exchange tag, I posted this here, hope you'll forgive me
