I would be very careful with RML shares. The increase in price has been on the back of KRY getting closer to a settlement with VZ based on the legal decisions. Nobody really believes VZ will allow Citgo to be auctioned off. When a settlement is reached and the legal action to auction off Citgo dropped all the groups trying to piggy back on KRY will be back to square one.
It wouldn't shock me to see people pushing RML higher to dump their shares to uninformed buyers. It's possible RML could be in settlement talks as well but given VZ's record of delaying it is risky to bank on that.
Just my opinion.
