Hi Winston,
You bring up a few interesting points. I am happy to share my thoughts.
1) It is true that a substantial portion of Noble earnings is derived from disposal of its assets and other one off gains made during acquisitions (eg Gloucester). This is why as an investor, I compiled a date on Noble's operating profit to see whether is there any upward trend to match the growth of its net profits.
1997: 486 2003: 68,525
1998: -7,663 2004: 314,719
1999: 6,629 2005: 253,626
2000: 24,961 2006: 487,527
2001: 27,186 2007: 823,685
2002: 33,012 2008: 1,347,598
2) Commodity prices affect the revenue while the volume of goods following through its supply chain affect its bottomline. This is why Noble Group consistently highlights tonnage growth while keeping silent on prices except to mention its risk-management and hedging of its inventories.
Personally, I am under the impression that a plunge or rise in commodity price is immaterial to a supply chain manager (if its due to currency flux and not physical demand). Most of the gain in futures price is due to ppl shorting the USD by using the weak USD to buy high yield assets in the hope of making a capital and forex gain.
However Noble Group is in the physical trading of items to real-life industries. What matters is demand and tonnage carried within the supply chain. The only time where price mattered is during times of great volatility since futures contracts can incur losses. Actually, besides the loss of market share through a decrease in tonnage, volatile prices are Noble massive threat.
If future prices rises furiously due to speculators on the trading floor but few industries are buying steel as there is little demand for goods, Noble will be hammered!
Last year after 3Q 2008, Noble Group CFO Steve Marzo explains how commodity prices HAS NO EFFECT in Noble Group as it profits is derived from the supply chain. Moreover, lower commodity prices, will help commodity firms de-leverage since less money is required for working capital.

4) Yes supply chain managers have razor thin margins averaging between 1-3%. Its very difficult to push the selling price up when your competitor is selling the exact same thing - coal, metals, oil etc.
5) BDI will affect its logistics business.
Despite the slump in commodity prices and the BDI, Noble net profit excluding one-off gains is in line with 2008 at $371 mil USD.
