Noble group, its bonds and more

I wrote a few times about Noble Group, but nothing recently. I was interested in the case because of the strange valuation of its holding in Yancoal. That valuation seemed way of the mark (needless to say, DCF was used, the weapon of choice for these kind of occasions). The logical follow-up question would be, if the same would apply to some of its other assets?

Its share price has since come down quite a bit, and more worrisome (recently) the price of its bonds.

"The Macro Tourist" wrote an interesting article about Noble "Was Noble the silver seller?".

It describes a possible involvement of Noble with silver. It is a speculative assumption, but it does show a few nice charts.
