Maybe it's because we are post all the choo choo times of Nov / Dec...
Personally, I don't find the dynamic particularly adversarial. But I don't take into account the vast majority of posting here. There's a small handful of analysts here that I think provide useful insight on a regular basis. 95% of this forum is trolling etc, and the rest I use to confirm, or compel reassessment of, my position. I wouldn't do that because someone says the price will go up or down; I do it because analysis is compelling -- or because it isn't. Any analysis I post is in the same vein.
I'm of the position that a) very few will take my calls seriously enough to act on them, and b) this forum is too insignificant to matter. But to be fair, even Lucif got burnt and learned this lesson -- surely people attempt to manipulate this way. Still, I think posting positions * here has more to do with the psychological push to be "correct." It's funny -- there have certainly been times when I have posted analysis here and been more excited for it to be correct than I have for the profit to be reaped. Silly, really, but that's ego....
Put another way, I think you would have to be very unintelligent at this point to believe you could move the market by posting on this forum. A few years ago, it was more sensible, but you would have to be quite stupid at this point. Perhaps my mistake is giving too much credit to peoples' basic intelligence.
* drawing a distinction between trolling and analysis
Yeah, didn't mean to be down on this place, and we are supposed to be on a speculation thread.
I think we all suffer from wanting to see affirmation of our desires, and confirmation of our predictions, even the best on here display their ego on occasion.
However, we all take a little from each call and get a feel for the mood through it, placing different weightings according to the respect we have for the poster concerned, in order to factor this in to our own view.
In this respect the thread is an indicator and I am sure it is watched. Sometimes it can even be a contra-indicator (when everyone is most bullish, it is sometimes a bad sign!)
I think almost no-one here believes they can move this market anymore, though - because I doubt any of us really has that power.
