A number of companies announce news after hours or before hours. I am not all that certain it matters when it comes out. Under the HOT! tag in the navigation bar there is a link in the drop box for "Recent news." You could do a comparison looking at companies that put out news before or after close versus during the trading day but I don't know if it would indicate anything in particular.
jkl - I think news being released after or right after the close is a sign of strength. Especially if it is positive news that would normally spike a PINKy. To me it says they are above the fray of the normal news driven pps game, and they are into slow moderate growth, ie strength.
