Difference Between Poker and the Stock Market

[midas]

I think it is a joke that people still think that poker and investing are remotely similar.

Poker is finite game with limited variables to understand, quantify and evaluate.

Investing or trading is an open ended "game" with hundreds if not thousands of quantifiable and psychological variables all with the potential to impact your results. Why do you thik that investment pros rarely beat indexes? It's too difficult - too may variables? Why did the housing/mortgage market recently create such an impact in the financial markets that no one anticipated? Because certain firms panicked together and caused market disruption.

There is no comparison. Most investment pros dont play poker and only few poker players are great investors.
