第9名：NII 控股公司

????交易代碼: NIHD

????年初至今股票表現: -55%

????市值: 35億美元

????財富500強排名: 406

????NII控股公司專門在拉美市場提供Nextel品牌對講移動設備。這家公司今年的表現可謂高開低走。第一季度業績強勁，營收和凈利潤同比增長了26%。

????接下來的第二季度業績也同樣強勁，NII決定將全年營收指導值從66億美元調高至71億美元，但后來證明這是個錯誤的決定——由于銷售額下降，匯率和稅項因素導致費用上升，第三季度業績沒有達到預期。NII隨后將指導值恢復到了第一季度的水平。

????“我們預計市場會對公司業績的作出消極反應，”摩根大通（J.P. Morgan）在10月份的報告中警告稱。2012年NII必須更努力，才能讓投資者重新相信它能在抵御競爭升級的同時，在巴西、阿根廷和秘魯擴大用戶規模。

NII Holdings

????Ticker: NIHD

????YTD stock performance: -55%

????Market cap: $3.5 billion

????Fortune 500 rank: 406

????It's been an up-and-down year for NII Holdings, which specializes in push-to-talk mobile communications in Latin America under the Nextel brand. The company posted strong results for the first quarter of 2011, with revenue and earnings up 26% year to year.

????With a second strong quarter in the books as well, NII decided to raise its guidance on annual revenue to $7.1 billion from $6.6 billion. But the move proved a mistake as third-quarter results missed projections due to lower sales and higher expenses related to currency exchange and taxes. The company reverted to its guidance from the first quarter.

????"We expect a negative reaction to the results," J.P. Morgan warned in an October note. NII will have to work hard in 2012 to restore investor confidence in its ability to increase subscribers in Brazil, Argentina, and Peru, while fending off growing competition.
