Can someone please ELIF what or who controls the market?

I just can’t make much sense of it. All I see are those sayings seen often

People currently thinking this is a bull trap for X reasons, but then those same people saying “who knows though”.

How is it possible that no one knows what’s going to happen, then those same people say there’s a 10% average? As well as this same people saying “past performance doesn’t equal future performance” etc

Just to summarize, people can point out history, but no one has any idea what’s going to happen?

Then everyone will act as if long term is some savior

If someone invests for 30 years or so then there’s zero risk in that and they’ll retire a millionaire lol

I’m just sort of lost on all this.

So if the economy is doing bad then the market could go up or down? Any good beginner websites?

So many of this makes no sense
