TheStreet's Jim Cramer says the stock price for Whole Foods might be as expensive as their food prices. Cramer says its important to understand that huge portfolio managers are looking to comparable store sales and asking what price to earnings multiple to put on the comparable store sales. While investors are paying 15 times earnings for Kroger, Whole Foods is demanding 25 times earnings. Something doesn’t add up. Cramer says Kroger is too cheap and Whole Foods is too expensive and that is why Whole Foods shares were lower after the chain reported quarterly results Wednesday evening. Cramer says Whole Foods is still a great operator and everyone likes to shop there, but the goods and stock price are just too expensive.
