all the markets are very thin at the moment and stocks are being marked down on very thin volumes, HRR is also prone to move on very little volume at the best of times, so today's markdown on a sale of 8000 shouldn't be a surprise.
I'm obviously not over the moon by the lack of upward movement of these, but I never bought them as a short term hold. If they are causing you undue stress and worry then sell them, your health and well being is far more important than any short term losses you may incur.
