In theory, what you say is quite sensible. But there is one interesting counter example I am aware of.The fragment tool compound that eventually gave rise to the clinical compound indeglitazar ( http://www.pnas.org/content/106/1/262.full.pdf) gives a negative shift by DSF (in our hands):

Hello, I am working on DSF to verify if some compounds bind to my protein. I see a negative shift of about 3-4 degrees upon ligand addition (dose-response) in comparison to the protein alone. I assume that this might be due to the binding of compound to the unfolded stated rather than folded
