If I recall correctly she was one of the analysts pumping the internet stocks during the dotcom boom and bust. IIRC (and I might not) she was also advising select clients to sell in the early stages of the bust as she publicly kept issuing strong buy recommendations on the same stocks for general audience. Thus I tend to view her analysis with a lot of salt.
