I wondering do really people belive bad news it's clear that bad news are there to just scare retail traders.
Sadly yes. If it's news that has been verified and tends to be a bad one, why wouldn't they believe it if it's a real thing that has happened? But, as we know in the market, when there is news being spread to give everyone the thought of being scared then it's up to you whether you'll allow them to scare you or you will use that moment so that you can buy. That's how it goes in this market, either you'll be the one to take advantage or you'll be the one that will be taken advantage of due to the news that they cascade down.
