Investing.com -- JPMorgan upgraded International Paper to "Overweight" from "Neutral," arguing that an improving U.S. linerboard pricing cycle and tightening supply-demand dynamics are likely to lift earnings across the corrugated packaging sector, with International Paper offering the most attractive risk-reward profile. The brokerage raised its price target on International Paper to $61 from $51, while increasing its London-listed target to 4,600 pence from 3,200 pence. The upgrade follows reports that Packaging Corp. of America plans to implement a $140-per-ton U.S. kraftliner price increase from Sept. 1. It said Packaging Corp. and International Paper remain the most leveraged to higher linerboard pricing, while International Paper stands to benefit the most from a valuation perspective given its currently depressed earnings base and higher financial leverage.
