You have to understand that gold and silver are hated in the good ole USA. They prefer you put your money into the scam corporations (stocks) who can steal your money. If you buy gold or silver bullion, they can't take it from you. Therefore, they manipulate the prices and the silver & gold mining stocks follow the metals closely. The manipulation can only go on so long before it blows up. The physical demand is growing and the paper market will collapse at some point.
Spot Silver market likely will always drive the mining stock prices. But, for me the stock is easier to do TA on, Maybe the overseas trading like chemaes noted makes it harder to do fib extensions and even TLs on than the stock SPOT just dropped again .. 22.10ish
