As Buffett says, "good ideas for investing are like patents and should not be broadcasted" (might not have the exact quote, but close enough). I agree with his approach of only disclosing the largest positions.
So far as Coke and some of the stock prices going sideways, this has happened before. There will always be some stock prices that advance and some that don't in a portfolio within a year.
You make a good point about the quality of the other permanent holdings.
