by Peter Schiff, Schiff Gold:

The Comex report for last month correctly identified a potential big move in silver while the same report two months ago preceded a massive up move for the price of gold. The data this month is not as obvious or compelling, but it is clear the stress on the Comex continues to build.

The CME Comex is the Exchange where futures are traded for gold, silver, and other commodities. The CME also allows futures buyers to turn their contracts into physical metal through delivery. You can find more detail on the CME here (e.g., vault types, major/minor months, delivery explanation, historical data, etc.).
