Bond questions | General financial discussion | Discussion forum

I understand the net bond yields decrease or increase when their NAV changes. Example a $100 coupon with a 5% yield would decrease in relation to its NAV to 4.5% if the NAV increased to $110.

1. Is the same so for bond ETF's? Example: NYSE: JNK shows a yield of 5.41% @ a NAV of 109.60 USD. If the NAV jumped to 150 USD, how would the yield change? Would the net yield drop to 3.95%?

2. Is there a way for me to see the underlining portfolio of JNK bond ETF showing me all the bonds it holds to see their real yields?
