I'm pretty sure that he doesn't, everything that he has tweeted is so obvious that anyone following this thread could post similar tweets and have a very high chance of being correct. I'm sure it's no coincidence that many of his tweets follow the release of data by someone else. It's the same as his "reports", where he just re-writes a news or financial report without sourcing it, and writes it as if he's the source, implying that he has inside information, re-inforced by slapping his name on graphs of other people's data. It does seem to actually fool a lot of people, judging by how many times his tweets have been posted in this thread. Then we have his hardware graphs where instead of using the available range for XB1 shipments (whilst they still gave combined shipments), he used his own methodology to extrapolate an estimate for XB1 sales, then slapped them on a graph as though his own guesses were the actual shipment, and then would just source his own graphs for what actual XB1 shipments were.
The guys a fraud, I'm not sure if I should be surprised or not that so many people have fallen for it.
