MOST NOTEWORTHY: Melco PBL Entertainment, Helen of Troy, LHC Group and Oriental Financial were today's noteworthy initiations:

• Jefferies initiated shares of Melco PBL Entertainment (NASDAQ: MPEL) with a Buy rating and $21 target, as they believe the possibility of A-Max, a VIP junket consolidator, moving up to 10 junkets to the Crown Casino could lead to short-term gains and notes that MPEL is the only Macau pure play in the U.S. stock market.
  
• Jefferies also started shares of Helen of Troy (NASDAQ: HELE) with a Hold rating and $21 target, as they sees risks to near-term EPS from soft consumer demand and gross margin pressures.
