When you say "supposed to happen" well that confuses me because we can not rely on outcomes that have yet to happen. The word "suppose" is a irrelevant term to me because the stock market is a huge unknown event based on emotion where anything could happen.
You may have missed the two words before what you quoted, "think" being the word. We are talking about investor psychology and attitudes. In terms of behavior and how people actually act, reality isn't actually what's important - it's perception i.e. what they think will or should happen.
You're basically arguing gaurantees versus what chances in the stock market - but people don't think like that and consequently, don't act like that (read: investor psychology). When the market goes down, we comment and explain away the results "Manipulation, the whole market is down, people don't understand this yet etc." I'm guilty of it myself. When it goes up, well - Finally, the market has caught on to my genius.
In relation to copper fox, that's why we see the stock price : comment ratio that we see. At least on these boards.
