Shiny Pokemon used to have a higher IV count. This was as I recall changed, and now Shiny Pokemon are no different from regular Pokemon other than the color.
As a general rule, no. The IVs/ stats of a shiny Pokemon are random (after Gen II) just like a normal Pokemon. It can be stronger than a normal Pokemon, or it can have the same usefulness as a cauliflower.
The only thing special about a shiny is its colour.
