Well, if you have edge, you don't write about it. So only not so interesting stuff is written about, the really interesting stuff is traded.
That's why I like market prices (including prediction markets) more than journalists. I once wanted to bet 100$ with a financial journalist ("analyst") so he has more skin in the game in his "prediction". He did not want to do it - he earns a salary as a journalist regardless of whether the stories he invents in his head are true or not. The real category of financial journalism is "entertainment".
(Here's a chapter from my book about prediction markets: https://juraj.bednar.io/en/blog-en/2021/06/23/prediction-markets-crowdsourcing-information-for-good-decisions/ )
