Let’s go back to our bucket. The bucket is full of water, a bunch of people are all waiting with their empty cups to try to scoop out more water than they put in. I am now going to announce that these people are all men. I am not being sexist, just that women are far too sensible to play games like this. Let’s say 75% of the guys are 170cm tall and weigh 160lbs dripping wet and 25% of the guys are 190cm tall and weigh 220lbs a piece. What are the chances that amount of water collected will be even between the smaller and larger guys? The chances are the little guys won’t even get close to the bucket.
Not only that, the little guys have egg-cups, the big guys have pint glasses and the bucket is leaking into the exchanges hands to pay all the costs of the "Financial Services Industry".
Now, before you go slit you wrists, having an egg cup isn't necessarily a bad thing.
That is, as long as you acknowledge one thing:
The markets are competitive. A lot of people chasing after the same money.
I get slated a lot for knocking TEXTBOOK TA on here. One of my major objections is that people think you can read a book, learn that when A and B line up it's time to trade and then print money off it forever. If Trading is really competitive, then an objective book-read approach won't work because in all competitive environments I know, it is your own skill that makes you a winner and not something you got from a book.
So - from me, that is all I have to say on the "Zero Sum" part of the markets but it will come as no shock that I have a bit more to say on the "So how can I benefit from this?" portion.
