For every market event you are always going to find someone who predicted it. People predict everything at every point in time.

Getting one prediction right doesn't prove anything. Getting a lot of them right also doesn't prove anything. No one has managed to show a streak of accurate predictions unless they silently purge their incorrect ones.

Humans have a tendency to focus on the successes and ignore all the failures. It's in human nature and it's very hard to avoid it.
