Resources, mining services, gold – they have all had a great run this year. Be careful to lump them into the same basket though. While I think gold has potential upside (see my previous post), I can see dangers signs in other parts of the commodities sector. The big Australian, BHP, is one stock which I think needs to be treated with some care here and you may be surprised at where the charts suggest it can fall to. I’ll explain what I am now seeing.
