The Foolish bottom line Domino's Pizza is one of the fastest-growing international brands and rising demand has led to great financial performances over the last few years. I believe the current expectations for its second-quarter results are well within reach, but investors will also want to keep an eye on its outlook, margins, expansion, and share repurchase activity. With all of this said, I think Domino's stock is undervalued at current levels, so Foolish investors might want to take a deeper look and consider initiating long-term positions soon.
