In search of Bigfoot
An investor panic over an FDA report that a number of patients taking Amylin Pharmaceuticals' Byetta, a drug it co-markets with Eli Lilly (NYSE:LLY), had died of pancreatitis turned into a rout when the companies announced an additional set of deaths. Yet investors like CAPS member gillet01 are aware of the risks associated with the drug, but also understand the benefits far outweigh the dangers.

Amylin is a bit of a one trick pony, but that pony Byetta (and it's soon to come LAR longer acting version) is a first in class drug treats one of the fastest growing diseases in the world, diabetes, with a major side effect of weight loss... The price has come down due to the reports of a number of deaths of patients on Byetta from pancreatitis. Time will tell whether this increase is directly related to Byetta, or merely a reflection of the patient pool being treated. What is clear is that even if there is an increased risk of pancreatitis, it is far outweighed by the overall decrease in morbidity by taking the drug. What isn't clear is how the hype may negatively effect usage.

Marathon Oil is representative of what may be new thinking that Big Oil has to break itself up into smaller pieces. CAPS member tscheiblich in particular feels that if it concentrates on production, it will ultimately do well even if the trip there is not smooth.

They're a pretty good bargain right now. If they are able to capitalize on the new estimates in North Dakota and the desire to emphasize domestic energy production, it should be a good long term play in the energy industry. It'll be a bumpy ride along the way, though.

Possessing a name synonymous with audio quality, Dolby Labs is expanding into areas outside its traditional format: HDTV and 3-D cinema, for instance. Top-rated All-Star CAPS member ll0o0ll sees this Stock Advisor recommendation as a prodigious producer of profits.

Dolby is a diversified way to play growth of electronic devices without exposure to pricing pressure in the industry. Inflation related covenants will help to increase top line in a high inflation environment we are facing. The company will also benefit from coming transformation of cinema screens to 3-D, adoption of digital TV, growth in game consoles and PCs powered by Vista Premium editions. There are also opportunities outside the traditional sound business (Dolby Contrast, Dolby Volume etc.)
