RE: HEE,X,P,F weighting Because these Horizon EFT's hold a basket of stocks I don't mind if my weighting in each is above my 'no more then 10%' rule. As for determining the n.a.v. good luck!, these are actively traded funds with covered call action on the side. There is no way anyone outside these funds could calculate n.a.v.. Instead follow the sector index for each fund daily/weekly to get a sense of direction. Use seasonality to determine which fund to be light or heavy weighted in.
