We, here at The Panelist, really enjoy our "full disclosure" policy. We encourage our writers to disclose everything about their relationships to a company, no matter how remote. Beyond disclosing whether they own a stock, our writers often disclose their use of the company's products, or those of a competitor. They will even go as far as to mention if they would consider buying the stock or if they like the company logo.
Whole Foods (WFMI – $39.00) CEO John Mackey subscribes to the opposite philosophy. According to an article at the Wall Street Journal by David Kesmodel and John Wilke, Mr. Mackey was making comments about competitors and pumping up Whole Food earnings reports on the Yahoo investment forums. Bad boy. You don't have to disclose if you enjoy the hairstyle of the guy bagging your groceries at Whole Foods, but you should disclose that you work for the company, receive options, are privvy to insider information, own stock and are the main decision-maker about acquisitions of other companies. 
Here is a link to what looks like Rebodeb's (John Mackey's secret identity) last entry on Yahoo Finance and all the comments of real people that follow.
I wonder, if the CEO had disclosed his entire relationship with the company and used his real name, if even that would constitute doing anything wrong. I mean, you have this great job being in charge of the world's largest organically, focused and healthy lifestyle food market. You have credibility and a great platform for changing the way people think about their behavior and the planet. What do you do? You throw it all away so you can make secret comments defending yourself. What poor judgement! Apologize and give your job to a CEO with good judgement, Mr. Mackey. Stick around on the board because you do have talent for growing a company and you can give good advice to the new CEO about corporate expansion. Please don't give him/her advice on how to use the Internet.
Disclosure: I do not own WFMI. I have thought about buying the stock several times but it always seemed too expensive relative to its growth rate. Besides, supermarkets always end up having low margins in the long run. Would I buy it now? At a trailing P/E of 28, growing earnings and sector domination, the stock is actually starting to get reasonable. I may buy it if the CEO gets in more trouble and his fall causes a drop in the stock price.
More Disclsoure: Do I shop at Whole Foods? I don't in Manhattan but I do when I'm elsewhere. In Manhattan there are so many other stores with better quality, better service and great produce that are closer and have shorter lines (with the same sky-high prices). Outside Manhattan, Whole Foods stores are great.
Ironic and Snarky Disclosure: Am I on the Yahoo Finance Messages Boards? Yes, I am. Like John Mackey, I also have a Yahoo pseudonym that is hard to figure out and disguises my identity. My secret psydonym is either NeubertDave or DavidNeubert. At least on John Mackey's Whole Foods blog he uses his real name. Though the ultimate irony would be if he had someone else write those blogs for him. Link to the Whole Foods FAQ on Mackay's postings on the yahoo message boards.
