the experts say you should look for core holdings
you can get that return from a cash ISA with nil risk
then even if it multibags it will only move your overal portfolio 1 or 2 %
if you have a small holding, say 1 or 2% of portfolio
certainly time to be watching carefully
that means i have lots not worth having!
the 'experts' say if a holding is less than 10% of the portfolio, then its not worth having
