Advance-Decline data

[Jim Johnson <jejohn@xxxxxxxxxxxxxxxx>]

Hello omega-list,

  I read McMillan's article in TASC last night about the junk that's
  included in the Advancing and Delcining issues data stream.  It
  seems a fairly compelling case (many issues are closed end bond
  funds that may change price by only 1 cent based on interest rate
  changes).  In addition, the 1 cent trade increment has cheapened the
  definition of an advance or a decline.  He does suggest that because
  these "bastard" issues (my term) have low volume, that advancing/
  declining volume may be a better alternative.

  As they say, this issue seems non-trivial.

  I appears that Neoticker's NeoBreadth product may attempt to create
  custom A-D indices.  Is that what it does, has anyone tried it?
  other thoughts on this data cancer problem amongst us?
