Is stock trading based more on luck than poker playing? 
I assert not so. Even if we assume a zero sum game (which is highly in doubt); the general stock market curves indicate the average player is so bad that you don't have to be very good to have better that 50/50 averages. One example: UP stock nosedived right after some political mess in Russia two years ago. Buy! Profit: half my money in a month. I knew that nosedive was senseless as UP doesn't have to care much about what goes on in Russia. Rising oil price was a reasonable prediction; however this is good for railroads, and most short-term market trends behave as if it is bad.
