A sputtering economy, implosions at financial institutions, or just plain bad management -- on any given day, investors can name a number of reasons to sell a stock. Yet, while panic is never beneficial to investors, it's good practice to play devil's advocate with investments from time to time.

In Motley Fool CAPS, more than 125,000 members have weighed in on nearly 5,400 stocks, sharing bullish and bearish opinions alike.

When looking at metal miner Goldcorp (NYSE:GG), a total of 1,897 members have weighed in on its chances of success. I've already plucked out some of the bullish rationale backing Goldcorp today, so here are three counterpoints to consider, courtesy of CAPS.

Too far, too fast. While a high P/E may be a strong buy signal for many investing strategies, some CAPS members feel Goldcorp is overpriced at current levels. Goldcorp and other commodities producers like Newmont Mining (NYSE:NEM), Yamana Gold (NYSE:AUY), and Freeport-McMoRan (NYSE:FCX) had a huge run-up in share price over the past several months, which some investors think was overdone, leaving them sitting on the sidelines waiting for cheaper share prices.

Strengthening dollar. A weak dollar generally pushes gold and precious metals prices higher. But the dollar has been seeing some recent strength, which could be bad news for many companies, including miners. There's also one camp that continues to see the U.S. dollar as a stable currency throughout the recession, which deflates one positive pressure behind gold prices.

Flat 2009. Metals and mining companies around the world like Rio Tinto (NYSE:RTP), Anglo American (NASDAQ:AAUK), and Vale (NYSE:RIO) have cut production for 2009 because of the economy. Goldcorp missed Wall Street's production expectations in its latest issued guidance, and it’s expecting a flat 2009. Coupled with the concerns about the stock's valuation stated above, some investors see little reason to be invested in Goldcorp at this point.

Of course, Goldcorp has survived and thrived over the long term, despite volatile markets. But the question about whether the company's future is as bright as the past is why CAPS is such a great resource to augment your own analysis.
