All stock markets are a plus-sum game.
Authored by: Anonymous on Tuesday, August 21 2012 @ 01:27 PM EDT
>there is a limited amount of coin in the world, all that happens is that it
changes hands. Which is the definition of a zero-sum game.

That's a fundamentally flawed definition of "coin". Corporate debt is,
like country debt, a form of value. The question is--is that value backed by
adequate productivity?

If no, then the value of the money decreases--a negative-sum game for everyone.
If there is more than adequate productivity, the value increases--a positive-sum
game for everyone involved.

The stock markets (and currency exchanges) are just people trying to get out of
the negative-sum games and into the positive-sum games. The markets themselves
are inefficient and fraud-ridden (that is, negative-sum). But are they MORE
negative-sum than NOT having the option of getting out of other games?

It's a kind of insurance, like medical insurance, or homeowner's insurance--or
social security. Inefficient, yes. Fraud-ridden, yes squared. But at its best it
hurts everyone, except the people who are being devastated by something else.

No, the stock market increases in value as the overall value
of the companies increases (they produce products).
Unfortunately, it also increases/decreases due to emotion -
which gives stock bubbles and stock busts. For those who
invest for the long term, and have a broad range of stocks,
it's a positive sum game. For those who actively trade,
it's a zero-sum, and a negative sum when you account for
brokerage fees.

The quickest way to end up with a small fortune day trading
is to start with a large fortune.
