NEW YORK (TheStreet) -- Pan American Silver Corp.  (PAAS - Get Report) stock closed down by 6.08% to $10.20 on Wednesday, after the company was downgraded to "hold" from "buy" at Deutsche Bank on Wednesday. 

Deutsche Bank predicts that the commodity price rally so far this year will not continue, the firm said. Silver prices have risen about 10% so far this year. 

"We are of the view that material supply cuts are still needed in most commodities and therefore do not anticipate prices continuing upward trend," the firm said. "We remain concerned that supply cuts may now take longer, with improving options for marginal producers in the last three-months, and capacity reductions grind slower-than-expected on competing stakeholder interests and high barriers to exit."

Additionally, declining silver prices are affecting silver mining companies such as Pan American. Silver for May delivery is falling by 3.87% to $15.30 per ounce on the COMEX this afternoon.

Based in Vancouver, Pan American develops and explores for silver, gold, zinc, lead, and copper.

Separately, recently, TheStreet Ratings objectively rated this stock according to its "risk-adjusted" total return prospect over a 12-month investment horizon. Not based on the news in any given day, the rating may differ from Jim Cramer's view or that of this articles's author.

TheStreet Ratings rates this stock as a "sell" with a ratings score of D+. This is driven by several weaknesses, which we believe should have a greater impact than any strengths, and could make it more difficult for investors to achieve positive results compared to most of the stocks we cover. The area that we feel has been the company's primary weakness has been its disappointing return on equity.
