Thanks. I'm going to maintain the UKB data resources pages into the future. I want to do a delisted stocks study at some time myself so I'm on the case. At the moment I filter the stocks with negative returns and use them for a barometer test on how my bull systems handle adverse conditions (and vice versa). My theory is that this is an adequate, if not superior test, but I would still like to take some notes on the behaviour of 'delisted' stocks to make certain. brian_z --- In [email protected], "haders2003" <[EMAIL PROTECTED]> wrote: > > > Hi Brian > > Had a reply back from Premiun Data today: > > We've gone through a longer-than-expected testing process but should > be in a position to provide this database in the coming few weeks.
