Investors continue to keep a close eye on the progress of companies involved in developing medicines targeting the central nervous system and, in the main, their reaction has been generally positive. The BioWorld Neurological Diseases index, a price-weighted index of public biopharmaceutical companies that are focused on developing therapies to treat neurological diseases, closed the year up over 16% and after, a dip in January, is now tracking up more than 12% by market close on Friday Feb. 21, well ahead of the general markets for the same period.

The BioWorld Cancer index, which includes 21 representative companies developing therapies targeting various cancers, entered the new year on a high note, after posting a 22.5% gain for the year. Unfortunately, the group hit a speed bump and the index took a beating in January, dropping almost 9% as a result.
