Organic food makes up about 4% of total U.S. food sales, placing it squarely in a niche category that other grocers can exploit, albeit especially Walmart and Target. Organic food products not only compete against other food products for shelf space, but more or less everything from aspirin to the windshield wiper fluid in Wal-Mart and Target.
Separating Safeway, SuperValue, Kroger, and Whole Foods Market from the kings of retail is how much additional floor space can be allocated toward organic foods. Growing sales and or margins will result in relatively greater space dedicated to organic foods until equilibrium is found.
In other words, outsized organic food margins will get squeezed until it's not advantageous for others to encroach further into Whole Foods' space. This is why the company lowered its guidance and will face headwinds moving forward.That said, Whole Foods is positioned to remain the leader in the space, but what shareholders failed to realize before the earnings release is that a stock trading with a price-to-earnings ratio of more than 30 requires top- and bottom-line growth to support a rich valuation. Using a forward P/E of 21 and $1.80 in earnings for 2015, we arrive at a stock valuation of $37.80. If you're buying Whole Foods for more than $38 this week, you're probably paying more than you need to. Whether the company can maintain a P/E more than 30% higher than its next highest valued competitor remains to be seen. As the organic sales leader enjoying fantastic consumer appeal, I believe a P/E is warranted.
