NEW YORK ( TheStreet) -- Whole Foods ( WFM) has been one of those stocks that I have always wanted to fall in love with, but just couldn't. Fundamentally, I value its healthy eating strategy and the company has demonstrated that is has an exceptionally sound business -- one that continues to grow despite severe economic concerns.The challenge for me has been its stock price. I have always considered it expensive. The market, however, has had different ideas. Investors can't seem to get enough and remarkably, the stock has developed the same appeal as Chipotle ( CMG) where valuation metrics have become unimportant. But I think it has now become time to take a more serious look at where things are and where they may be heading.
