Make sure you read down to that awesome anecdote about "mosaic theory" how large investors profit off of private meetings with executives even though sharing "material information" is illegal.

The analyst paid close attention to the discussion of the chairman’s spa trip and charity polo match, and got a strong and accurate sell signal from that discussion. Surely the most useful information in the meeting came from the guy’s tan. If you describe an executive as “unfeasibly tanned” in a research note, you have definitely decided to sell. Here, that was the right call.
