I don't think there is a magic number, but I imagine anything between about 20 and 60 is easily defensible, given your time, financial resources, knowledge, etc. I'm up to 26 positions, after 6 years of diligently building my portfolio. I will continue to add opportunistically. I probably would not even think about capping the number -- on principle alone -- until I'm around or above 40 positions.
