Super investor ownership

5 of the funds we track reported a position in their latest SEC 13F filing. Largest first:

A word of warning on reading these figures: a 13F reports the market value of a holding, so a fund that traded nothing at all still appears to have sold when the price fell. We found 102 companies where the standard reading gives the opposite answer. Only the share count is honest.
