I'll sell - plenty of other promising fish in the sea !
If you actually owned the stock, you'd know how much it was up since last year's split and you wouldn't even think about selling unless you were devastatingly stupid.
So you are smarter than the vast majority of analysts who call KO one of the single best stocks to own? I own a hefty number of shares in this company and will continue buying. You go after those "other fish." :)
