The Motley Fool (fool.com) has an entertaining contest going on right now, to find the "World's Scariest Stock":
My own vote:
SCARY: Crocs, Fannie Mae/Freddie Mac, Palm, Research in Motion and Sirius XM Radio (Palm and RIM basically because, in the long run, they will not be able to compete with Apple and Google).
SCARY AWESOME: Baidu, First Solar, Goldman Sachs and Pfizer.
It is interesting to note that of last year's top 10 scariest stocks, only Citigroup and First Solar underperformed the market. Starbucks actually returned 80 %, whilst Dendreon (a biotech company) returned nearly 500 %!
