Equity Insights May 30th: Research In Motion, Madison Square, Amarin, SLM, Wal-Mart

Research In Motion Limited (NASDAQ:RIMM): Jefferies lowered its price target for Research in Motion shares and reiterates an Underperform rating on the stock after the company preannounced an operating loss in Q1 due to lower handset volumes and selling prices. The firm believes RIM’s hiring of strategic advisors does not indicate a sale is imminent and thinks the company’s Q2 results will be worse than Q1.

Madison Square Garden, Inc. (NASDAQ:MSG): Morgan Stanley raised Madison Square Garden estimates based on stronger Q2 affiliate revenue. The firm remains above Street estimates and maintains its Overweight rating.

Amarin Corporation plc (NASDAQ:AMRN): JPMorgan says yesterday’s District Court ruling upholding the validity of patents for the Lovaza heart medicine and delaying the introduction of generics is a clear positive for Amarin. The firm believes the court ruling clears the way for Amarin’s AMR101 to launch and price without competition from generic Lovaza products. JPMorgan reiterates an Overweight rating on shares of Amarin.

SLM Corporation (NYSE:SLM): Barclays said SLM’s increased $400M buyback announcement was generally unexpected and should be a catalyst for shares. Shares are Overweight rated with a $18 price target.

Wal-Mart Stores Inc. (NYSE:WMT): Barclays has increased confidence in Wal-Mart’s ability to drive top-line momentum, productivity, and leverage. Shares are Overweight rated.
