The Dogs of the Dow sure were growling this week.

Six companies in the Dow Jones industrial average—Boeing, Pfizer, United Technologies, Visa, American Express and McDonald's—traded in serious correction territory the past few days. All six were down more than 10 percent from their 52-week highs.

Which one, if any, could be a screaming "buy"?

"The one that's getting really beaten up right now that could be really interesting is American Express," said Gina Sanchez, founder of Chantico Global. "American Express is obviously very leveraged to the consumer story. And everything that has had any consumer bent to it has just gotten beaten to death. But if you look at their second-quarter earnings results, they've actually been quite good."

Sanchez, a CNBC contributor, cites growth in the company's billing business as one reason to like American Express. "You're looking at a company that's actually doing quite well despite the fact that a lot of folks in the consumer space have been suffering," she said. Falling unemployment, higher wages and a subsequent increase in disposable income could provide tailwinds ahead for the company's business, according to Sanchez.

"Given the correction we've seen in the price, it does make [American Express] look really interesting," she said.

The technicals on American Express agree with Sanchez, according to Craig Johnson, senior technical analyst at Piper Jaffray. "Even though we've had this correction in the name, it is really just a pullback to the uptrend support line that's been intact for multiple years in here," he said. "Whenever we see these kinds of selloffs and pullbacks to support, I find that a great buying opportunity."

Johnson thinks it's not just American Express that could see some upside ahead. He thinks all six Dow companies that traded in correction territory could see a bounce. "There [are] some pretty good support levels just a little bit lower than where we are with these names," he said. "I think it's going to end up to be a pretty good buying opportunity not only for American Express but for the other 'Dogs' out there. "
