Hi bambam074
PTB - approx 1% of my portfolio. For comparison, at present the highest % I have on one Co. is approx. 8% - WES (purchased at much lower prices in the GFC and price appreciation has increased WES as a % of my portfolio - approx 11 % if I add back COL that was split off to WES shareholders).
As you stated above - not investment advice.
