Richards hadn't yet provided Seeking Alpha with additional information confirming the stock ownership, Moriarty added. In his response to this story mentioned above, Richards doesn't answer any of the stock ownership questions raised about his fund, Williams and Wurlitzer. Efforts to reach Williams and Wurlitzer weren't successful. Wurlitzer has been published in two medical journals, according to a search of the PubMed database. The first, in 2003, was a comment on an article about physician-detectives in 20th century literature. The second Wurlitzer piece, from 2010, commented on an article describing burnout among U.S. surgeons. Last fall, Richards wrote several Seeking Alpha articles claiming Roche ( RHHBY) was in talks to buy Aeterna for "over $4.70 per share." No such deal has been announced. In Tuesday trading, Keryx shares were dwon 16% to $4.13 while Aeterna shares were down 15% to $1.83. --Written by Adam Feuerstein in Boston. >To contact the writer of this article, click here: Adam Feuerstein. >To follow the writer on Twitter, go to http://twitter.com/adamfeuerstein. >To submit a news tip, send an email to: firstname.lastname@example.org.
