HF will most certainly rebound. The only question is when, not if. You only need to look at the performance in the PBT for the last quarter of year 2012 to see what the performance for 2013 is likely to be, other things held constant.
As long as it remains below 20, methinks it is a steal. Of course it was even better at 15 but couldn't get enough. I am taking the opportunity to add more while it is out of favour.
