    Central Limit Theorem & Trading

    The more your portfolio is diversified, the closer your return seems to be Normal-shape, I agree. Although return might be NOT good enough in short-term, your return SHOULD be more secure. Furthermore, instead of Normal-shape, it may be Log-Normal, if I heard correctly.

    Anyone in LA, have been in COMMERCE recently?

    Sooner or later, hope to visit LV. But they do not dislose table running info, before we visit there. I heard LV is terribly down in economic crisis. I wonder if they can open Holdem game. However, since I heard even in 911 they open poker table, there might be some game and players in LV too.

    Can anyone show examples of people getting trapped/areas of people losing money?

    Don't forget "stock market is zero-sum". Furthermore, as long as there is tax and commission, the market is minus-sum. If tax+comm takes 5% of all available money in all people, then most will be broke after 20 years. It is well-known that only 5% will be a winner IN THE LONG RUN, specially...

    There are two parts of expense, KRX(in Korea, such as NYSE) + brokerfee. And possibly, your local broker in US charges some fee to you, as well as hidden broker in Korea.

    Is Day Trading Inferior to Swing Trading?

    If I heard correctly, 1) There are more down day than up day. 2) Most increasing happens during the night, instead of during the 9:30 and 4:00. If so, average day trader will more likely lose money, than average swing traders who spend at least a night.
