Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of Paramount Gold and Silver (AMEX: PZG) fell nearly 13% on big volume in early trading, continuing a weeklong slide that has seen the stock lose more than 18% of its value over the past five days.

So what: Paramount is suffering not just from falling gold prices but also the Jim Cramer Effect. He slammed the stock during Friday's episode of Mad Money, saying the whole gold sector was heading south over the short term and that Paramount was not his "favorite" to own.

Now what: I'm not a gold analyst so I can't tell you whether the fall in Paramount is justified. Cramer may be right. Analysts aren't expecting the company to record profits during the foreseeable future.

Even so, when it comes to situations like these I'd rather get advice from a gold expert like fellow Fool Christopher Barker. When asked which gold stocks he liked most entering 2011, Paramount didn't make the list and it still doesn't. (Click here to see his top pick right now.)
