Well ok, but how can you prove the correlation ?

  That's the point. Of course the tweet may have been replicated everywhere as important news does. Every newspaper should, in fact, repost it, but was really just the tweet what peaked the stock's values?

  I think you meant prove the causation. I can prove they're correlated: they both happened! You're right that it's always good to be skeptical about extreme claims, but I think in this case it's pretty reasonable to assume that AAPL stock jumping when a famous investor announces "I bought a billion dollars of this stock and it's still undervalued" isn't a coincidence.
