Following a multiyear bull run for restaurant stocks, the operating environment is becoming more challenging. The competition in the restaurant business has always been fierce, but there are other factors at play that may help derail the restaurant bull market.
Given the run-up in beef prices, and other commodity costs, restaurants that have not passed rising costs along to the consumer yet, may ultimately have to do so. It is unclear whether consumers will be willing to pay more. Those chains that hold the line on prices will see profit margins slip, and stock prices may follow.
Pressure on labor costs may also be an issue, given the push for a higher minimum wage. That would hit the restaurant industry hard, given that labor is typically the largest expense.
Add to this the valuation factor -- the average restaurant stock trades for more than 35 times trailing earnings -- and there's ample reason to be cautious.
As for McDonald's, today's earnings shortfall doesn't spell doom for the fast-food giant. The stock trades at less than 16 times 2015 estimates, a small price to pay for 20% profit margins.
If the restaurant run-up is indeed on its last legs, there are plenty of other restaurant stocks that will likely be hit much harder. More on that in a future column.
