that will depend on what kind of news you are reading . if that news is fake or only created on the forum or on social media sites without giving any information about its source then theres a big posibility that news was fake and shouldnt be an indication of your predictions .
But, people are easily believe those hoaxes as long as it looks promising, they will use it as reference and believe it as a 'right' source and it may lead to something bad.
Also, hoaxes are common thing in the internet so it would take a part on price movement.
