Macquarie reels in expectations on containerboard sector

• Macquarie turns cautious on the containerboard sector.
• KapStone Paper & Packaging (KS -5.5%) is cut to Neutral from Outperform. The price target is lowered to $26 from $31.
• Price target reductions on International Paper (IP -3.7%), Packaging Corp. of America (PKG -3%), and RockTenn (RKT -3.7%) were also fired off due to a pricing cut on West Coast containerboard which tips more downside risk.
