What do an investor, a trader and a gambler have in common? Hans Wagner argues that an investor, trader, and gambler are similar because they have rules they operate by. I'd like to say there is a larger similarity, perhaps in the content of the rules, but Wagner is not making that claim as fas as I can see.
Important elements are:
conserving capital / cutting losses
the importance of temperament / personality
finding good trades Fundamentals agree with technicals.
