This is a simplified version of the truth. There is a lot of information that you can safely share because the number of people that will know where to look for it, know how to implement it, what to even do with it, how not to make any one of 100possible stupid mistakes while implementing it - is very low.

Not exactly. We know the broad strokes. He figures a price for a company by estimating their lifetime earnings and then factoring in the time value of money. He's talked about a mental checklist he goes through when looking at quarterly reports, but he never talks about the exact details of this process. Whether he's lost his edge, that's debatable too. The time since he's beaten the S&P is now entering into the long-term.
