当有人需要苹果时候,你在市场购买一箱苹果,马上给他,从中获取差价,就是套利。不是换个市场卖那么简单,毕竟苹果有时效性,换个市场卖没卖完会坏掉。
例子,有个运营商要推出冲200话费送200商城指定购物券活动(假设活动可以每人每次冲200可参与两次),那么你是A,你去找个B,由B领头带领朋友同事去参与,而他们哪些同事朋友不需要购物卡,需话费作为前提。假设C在B带领下冲了200得到200商城指定购物券,你作为A给了C200冲话费,因为这200是你出的,参与了第二次活动,所以,第一次活动送的200加上第二次活动送的200,当前你出了200现金得到了400商城指定购物券,为了对BC有好处,你需要给BC各10元辛苦费,所以消费220现金得到400商城指定购物券。作为商城指定购物券,购买的东西必定达不到400的,但是也会比220现金高出一部分,这部分就是套利所得。
楼上大哥们说的是金融市场总的套利行为,需要大额资金和丰富经验才能参与。

什么是套汇和套利?有什么形式?
(1)套汇
所谓套汇,就是利用两个或三个不同外汇市场之间某种货币的汇率差异,分别在这几个外汇市场上一面买进一面卖出这种货币,从中赚取汇率差额利益的外汇交易形式。套汇的主要形式有直接套汇与间接套汇两种。
①直接套汇。直接套汇又称两地套汇,是指当两个不同地点外汇市场上某种货币汇率出现差异时,外汇交易者同时在这两个市场买贱卖贵,从中赚取差价利润的交易行为。
②间接套汇。间接套汇又称三地套汇,是指套汇者利用三个以上不同地点的外汇市场在同一时间内存在的货币汇率差异,同时在这些市场上买贱卖贵,套取汇率差额收益的交易行为。
(2)套利
套利活动主要有两种形式:
①“不抛补的套利”。主要是指利用两国市场的利率差异,把短期资金从利率较低的市场调至利率较高的市场进行投资,以谋取利息差额收入。
②“抛补的套利”。是指套利者在把资金从甲地调往乙地以获取较高利息的同时,还在外汇市场上卖出远期的乙国货币以防止风险。
套利活动的机会在外汇市场上往往转瞬即逝,套利机会一旦出现,大银行大公司便会迅速投入大量资金,从而使两国的利差与两国货币掉期率(即远期汇率与即期汇率之间的差额)之间的不一致迅速消除。所以从这个意义上讲,套利活动客观上加强了国际金融市场的一体化,使两国之间的短期利率趋于均衡并由此形成一个世界性的利率网络。同时,套利活动也使各国货币的利率和汇率之间形成了一种有机的联系,两者相互影响,相互牵制。从这一点上看套利活动实际上是促进国际金融一体化的一种重要力量。

你知道什么是套利吗?
2、arbitrage pricing theory
首先看看,套利定价理论(Arbitrage Pricing Theory)房器名农友困短毛校息,中的Arbit增脚代快的优rage翻译为套利,是指粒景还局但言轴装本门占在一个市场购进股票, 而在另一市场卖出, 以赚取价格的差额。
再看看,套利定价理论的模型,E志形否场乱汽缺春(R)=Rf+b1入1+b2入2+...
套利定价模型的基本理论认为:同一个风险因素所要求的风险收益率对于所有不同的文食叶改资产来说都是相同的,因此每个“入”的大小对于半不同的资产都有同害找界件住夜艺导样的数值。否则,如果某个风险因素对不同的资 产提供了不同的收益,投资者就可以通过适当调整手中资产组合中的资产种类和比例(即通过买卖股票等“套利”活动),在不增加风险的情况下获得额外的收益。而这种套利活动的结果,就会使得这些额外的收益逐渐变小,以致最后消除,达到市场均衡。
