Indeed always opportunities and although I missed PAZ, I'm happy with PLX in my portfolio.
Must say the assumption that one would stick with one company for 10 yrs as a viable strategy is a bit suspect IMHO. ATM has so far been my longest investment at 5 yrs, and while I may well still hold some in 5 yrs, it is more likely that I'll have considerably reduced my holding and re-invested elsewhere.
It might be interesting to see what actual NZ companies investors have stuck with for the last 10 yrs and who has done best?
