跑赢大盘的方式有几百万种，而iBillionaire选择的方式我猜比任何一种都不差。

    iBillionaire最开始只是一款iOS应用软件(iBillionaire)加一个网站(iBillionaire.me)，去年10月底，它摇身一变，成了一个交易型开放式指数基金(ETF)，为投资者提供一个30只股票的投资组合，复制沃伦•巴菲特、乔治•索罗斯和卡尔•伊坎等21位亿万富翁投资者的投资策略。

    下面是iBillionaire的宣传词：

    “我们对20多位亿万富翁持有和管理的2500多亿美元资产进行分析。每个季度我们会查看约1,500项投资，其中93%是股票，7%是其他资产类型。我们的软件处理SEC申报文件已有10年多，确保iBillionaire指数是一个由优质公司组成的多元化投资组合。”

    There are a million ways to try to beat the market, and the one iBillionaire has chosen is as good as any, I suppose.

    What started as an iOS app (iBillionaire) and website (iBillionaire.me) morphed at the end of October into an exchange-traded fund (ETF) that offers investors a portfolio of 30 stocks selected to mirror to the investment strategies of 21 billionaire investors -- people like Warren Buffett, George Soros and Carl Icahn.

    Here's the iBillionaire pitch:

    "We analyze more than 250 billion dollars in assets held and managed by a pool of over 20 billionaires. Each quarter, we look at roughly 1,500 investments, 93% in equities and 7% belonging to other asset classes. Our software has processed over a decade of SEC filings to ensure that the iBillionaire Index is a diversified portfolio of high-quality companies. "

    它的目标很简单：跑赢标普500。

    实际表现如何？

    迄今为止，还不错。10月31日以来，iBillionaire基金的涨幅为7.3%，高于标普500指数的4.8%。我想，可能出现的一个问题是，如果事态快速发展，iBillionaire可能总是比真正的亿万富翁慢一拍。

    The goal is simple: Beat the S&P 500.

    And how's that working?

    So far so good. Since Oct. 31, the iBillionaire fund is up 7.3% compared with 4.8% for the S&P 500. The catch, I suppose, is that when events unfold quickly iBillionaire will always be a beat behind the real billionaires.

    Note that in both cases, Apple (AAPL) is the No. 1 security, although it is weighted more than three times as heavily in the iBillionaire fund than in the broader index.
