The Domino's Pizza share price is up 3% to $18.56. This appears to have been driven by the release of a broker note out of UBS this morning. According to the release, the broker has upgraded the pizza chain operator's shares to a buy rating with a $22.00 price target. It made the move largely on valuation grounds following recent share price weakness. In addition, it notes that the company is aiming to cut costs quicker than expected, which could result in improved store profitability.
