NEW YORK ( TheStreet) -- The markets closed lower on Friday, snapping a six-week win streak.On CNBC's "Fast Money" TV show, Guy Adami said that Iron Mountain ( IRM) could be worth a look after it held its lows from 2012, despite the IRS scrutinizing the company's REIT eligibility. Brian Kelly said he isn't the biggest fan of Alcoa ( AA), but the chart is setting up nicely and the news of Russia looking to stockpile aluminum bodes well for the company. Walter Energy ( WLT) and Cliffs Natural Resources ( CLF) are breaking out, according to Tim Seymour. He said that if iron ore goes higher, so will these two stocks. Josh Brown said there is a fundamental shift towards global growth, and international PMI data seems to confirm that. He thinks the Vanguard Materials ETF ( VAW) is the best way to play, as long as the market doesn't give out. Kelly said to go with the gold miners, since a bottom may be in the for the yellow metal. He added that traders could look to the Market Vectors Gold Miners ETF ( GDX) or to the SPDR Gold Trust ETF ( GLD) to play a rise in gold prices. American Eagle Outfitters ( AEO) was the first stock on the show's "Pop & Drops" segment, which was down 16% for the week. Adami said traders could look to take the long side with a very tight stop. Potash ( POT) was up 4% on the week and Seymour said the stock will continue to go higher. Brown said First Solar ( FSLR) has finally given investors a pullback to buy, after an okay quarter. Sony ( SNE) was down 7% for the week and Kelly said to avoid it because the Japanese stock market looks like it has more downside ahead. Cisco Systems ( CSCO) reports earnings Wednesday. Seymour said the Street will be expecting an increase to the dividend and strong sales. He added that the company had two good quarters in a row, but has seen resistance at $27. Adami said buyers could look to get into BlackBerry ( BBRY) to squeeze the shorts, but the stock never seems to find a true bottom. Priceline.com ( PCLN) popped after beating on top- and bottom-line earnings estimates. Brown said the stock will probably hit $1,000 per share soon, but he prefers Google ( GOOG).
