Just wondering, how concentrated are the forum members normally?
I run a 15-25 stock portfolio. During the 2008-2009 downturn there were many more names because lots of things were cheap, and I thought a basket approach would minimize risk. Currently though, I'm much more concentrated, with 22% of the portfolio in one stock and large 8% or so positions in others.
I think if you run a 5 stock portfolio, it places a large premium on being right, whereas a diversified portfolio composed of value picks will likely work out on an actuarial basis.
