Question ambiguity

Hubdub has had a few questions appearing such as, "Will Dow Jones be up on February 8,2008?" The problem with this is the phrasing "be up". It is open to multiple interpretations depending on the reading and could result in a settlement different to a users belief in what the question asked. Better questions are "Will the Dow Jones Close up on Feb 8?" This can be very reasonably settled as whether the Dow rose or fell that day.
