Why fundamentals and opinions don't work in markets? Because the price reaction to 'fundamentals' or 'news' or 'Reuters poll' is never consistent.

And the top traders are always looking at 'fundamentals' because they want to justify their position with 'something' and deny the actual price action. The conversation I heard was on how the Reuters poll estimates of stock figures would come in at 1.93 or 1.95 million tonnes of cpo, which is utterly useless in market price action. It is only a safety blanket to blame losses on and not be accountable to own losses.
