In tonight\'s Cabot Market Letter, we write about the fact that, while not extreme, investor sentiment has finally shown signs of worry ... a good thing for the market. We also write about some interesting parallels between the blast-off in one market sector 10 years ago and the recent action of one of our Watch List stocks today. And, of course, we also review our five Model Portfolio stocks, as well as many names we\'re considering for new buying.
