Dollar General (DG) gets a downgrade at Deutsche Bank, Lowe's (LOW) gets a downgrade at Canaccord Genuity and Keybanc Capital Markets is bullish on Vince (VNCE). Deutsche Bank says it is lowering its rating on DG to HOLD from BUY even though Dollar General remains one of the best managed retailers around, stiff price competition from the likes of WalMart, Target and Family Dollar are making the environment more challenging. Deutsche says it expects Dollar General to post 3-4% same store sales growth in 2014. Canaccord Genuity is downgrading shares of Lowe's to SELL from HOLD because of slowing housing momentum, management changes and tough competition from Home Depot. Keybanc Capital Markets is making a bullish call on Vince moving to a BUY from HOLD and putting their price target at $31 a share. Keybanc says the move is based on the long term growth prospects for the jeans and casual apparel maker. Ruben Ramirez reports from the New York Stock Exchange.
