Can somebody explain to me howww??
I've read that book, but I forgot he said short term trading is a zero sum game. That is a very dangerous misconception since short term trading involves a lot of buying and selling, which means lots of brokerage costs and slippage. It is a negative sum game. If you end up break even in the very long term (by that I mean 30 or 40+ years, 10 years is not long enough), you are already a winner.
There is also long term trading/speculating which is far superior to short term speculating, IMHO.
Everyone knows value investing is a positive sum game because the company creates value, given that you picked a quality company. And the economy grows, given that you picked a lucky country.
When a company offers a good/service to its customers, it would gain value for each good/service sold, unless of course the company is idiotic that decreases its value each good/service sold. Over time these lemons will go bankrupt or reduce to insignificance. These lemons would be better off closing its factories or stores and return the capital to its shareholders now rather than destroying value.
But just being able to offer value creating goods/services is not enough for investors, since some dishonest insiders will take the value away from the investors to their own pockets. Therefore picking a good company is so important.
I think what I do is borderline of long term investing and long term speculating. Sometimes short term investing if lucky.
