As previously reported, BofA Merrill Lynch analyst George Staphos downgraded International Paper (IP) and Packaging Corp. (PKG), each to Neutral from Buy, following "disappointing" March containerboard industry data points reported today. Box shipments were down a "surprising" 3.0% year-over-year and inventories declined 47,000 tons, said Staphos, who believes the industry needs to drop inventories 400-500K tons between February and June to get back into balance. The analyst, who now anticipates an increased likelihood of another price cut during Q2, lowered his price target on International Paper shares to $50 from $53, cut his price target on Packaging Corp. to $107 from $112 and lowered his price target on WestRock (WRK) to $41 from $43.
