MOST NOTEWORTHY: Motorola (MOT) and Lions Gate Films (LGF) top today's modest list of upgrades.

• Matrix USA upgraded Motorola, Inc. (NYSE:MOT) to Strong Buy from Buy as it believes strong demand for handsets is leading to increased market share for the company. Matrix set Motorola's intrinsic value at $34 a share.
• Janco upgraded Lions Gate Entertainment Corp. (NYSE:LGF) to Buy from Accumulate based on the belief that the Street overreacted to the third-quarter earnings miss and underestimated the probable 2008 inflection point in EBITDA.

OTHER UPGRADES:

• C.E. Unterberg upgraded Hurray! Holding (NASDAQ:HRAY). The firm expects Hurray! to report solid third-quarter results and guidance, and said the company is a potential takeover target given its music assets.
• Suntrust Robinson Humphreys upgraded Barnes & Noble, Inc. (NYSE:BKS) to Buy from Neutral based on improved visibility and modest comps.
