新鲜多汁的“苹果”

Nice juicy Apple

尽管卡尔·伊坎仍在陷入困境的电脑生产商戴尔公司搅和，他已经抽出了时间力争另一家科技巨头。8月13日，这位积极的投资老手透露他已经持有苹果的股份，但是具体持有多少则避而不谈。然而，伊坎先生的意图很明确：他想要这家消费电子产品巨头扩张计划，将1470亿美元市值里的部分资金以现金和有价证券的形式返还给股东。文档来自于网络搜索

ALTHOUGH he is still stirring things up at Dell, an ailing computer-m aker, Carl Icahn has found time to tilt at another tech titan. On Aug ust 13th the veteran shareholder activist revealed that he had built u p a stake in Apple, though he stayed mum about exactly how many share s he had bought. Mr Icahn’s intentions, however, are crystal clear: he wants the consumer-electronics behemoth to expand plans to return some of its whopping $147 billion of cash and marketable securities t o shareholders.文档来自于网络搜索

伊坎先生也仍在从戴尔公司争取更多的钱，他正在游说股东反对一起收购。这项收购计划是由戴尔的创始人迈克尔·戴尔和一家私募股权公司银湖发起的。来自伊坎先生的压力已经使收购方提高了3.5亿美元的价格，使得收购价达到了248亿美元。他已经将斗争带到了法庭，通过投标争取得到更多的钱。文档来自于网络搜索

其他的科技公司也吸引了不少积极投资者的注意。今年早些时候，一个投资基金ValueAct Capital表示其持有了微软公司20亿美元的股份。加拿大银行捷豹金融也鼓励陷入危机的黑莓创新思维。今年8月12日，黑莓公司表示其正在探索战略选择，包括结盟和出售公司。一家对冲基金艾略特管理公司游说数据存储公司NetApp做出改变，该公司认为NetApp能做出更多来提高股东的收益。文档来自于网络搜索

And Elliott Management, a hedge fund, has been lobbying for change at NetApp, a data-storage firm that it thinks could do more to improve returns to shareholders.文档来自于网络搜索

积极投资人瞄准科技公司的一个原因是，很多科技公司跟苹果一样在经济衰退时拥有很大的现金流，但是资金利用不足。金融家希望他们放松自己的财政，放出更多的现金。伊坎先生想要苹果增加并加速其股份回购计划。现在该计划是截止到2015年末，苹果公司返还600亿美元给股东。文档来自于网络搜索

积极投资者瞄准科技公司的另一个原因就是科技的日新月异甚至会搞垮行业巨头。看一看微软的例子，在个人电脑时期成垄断之势，而在平板电脑智能手机时代则处于苦苦挣扎的境地。投资者希望通过推动公司做出更快改变适应市场变化来挣得更多利润。文档来自于网络搜索

报酬是实质性的。在活跃对冲基金第三点公司的怂恿之下，雅虎在2012年7月任命梅丽莎梅耶为新CEO。上个月她任职一年，这家陷入危机的互联网巨头股价上升了70%。7月，这家对冲基金回卖了一大笔股票给雅虎。伊坎先生认为苹果如果听从他关于回购的意见的话，其股价也能大涨。8月14日苹果的股价为每股499美元。这周他发推表示他跟苹果老板蒂姆库克有一个很愉快的对话，尽管

A recent study found that men consume an (3)__________ 433 calories (equivalent to a McDonald's double cheeseburger) on days they drink a moderate amount of alcohol.

Research bolstering the role of moderate drinking in helping to c ontrol weight gain was published in 2004 in the journal Obesity Resea rch. That study followed nearly 50,000 women over eight years. An ear lier study, published in the American Journal of Epidemiology in 1994, followed more than 7,000 people for 10 years and found that moderate drinkers gained less weight than nondrinkers.
