I agree it is crazy. There is no reason for the miners to get pulled down. Somebody is working hard to shake everyone else out of the miners. Don't let go of your shares. Gold had a relatively minor correction today given its recent runup. The miners have barely gone up at all. Somebody is out there shaking down the miners every time gold falls a little.
This is caused by redemptions and margin call triggers. When a client wants his money they have to sell something. Also when margin calls come calling they have to sell something. Usually finding large buyers is hard unless you are selling gold stocks or quality stocks. This is what is pulling it down not any issue with the company themselves.
