CNBC's Stock Pops & Drops From December 8

In a segment of CNBC's Fast Money called "Stock Pops & Drops", Tim Seymour commented on a 11.32 percent move lower by Yandex NV YNDX. He sees this as a devastating blow on a company that he has been bullish. The Russian company is struggling because the weakness in ruble is bringing down its revenues. Seymour likes the stock, but he doesn't think that traders should buy it immediately after the decline. Best Buy Co Inc BBY spiked 2.69 percent and closed at $36.59 on Monday, but Dan Nathan believes that this stock is heading to $30 in January or February. Guy Adami thinks that a decline in crude oil price is working against the rails, but he is prepared to buy the dip in Canadian Pacific Railway Limited (USA) CP, because he sees a support at $180. Pete Najarian explained that TASER International, Inc. TASR dropped 6.04 percent on Monday on a downgrade. He thinks that there is more room on the downside for this stock.
