做美股交易的朋友一般都知道QQQQ这支股票,它是跟踪那斯达克100指数的ETF指数基金。ETF的英文全称是Exchange Traded Funds,它在中国大陆被译为“交易所交易基金”,在香港被译为“交易所买卖基金”,在台湾被译为“指数股票型基金”。
QQQQ,SPY和DIA等ETF指数基金已经成为机构投资者和个人投资者的宠儿,ETF指数基金每天的交易量达到美国股市总成交量的一半以上。它们之所以大受欢迎是因为投资大盘指数比买卖个股的风险低很多,也比投资共同基金的整体回报高(70%以上的共同基金的年回报率都比不上大盘指数)。很多股民热衷于个股交易,不喜欢ETF,觉得ETF回报不高、不够刺激。
但是,你知道吗?目前市场上正在流行的双倍回报的ETF指数基金已经完全可以满足投资者对低风险和高回报的需求。我们这里所说的双倍回报的ETF是ProFunds公司发行的Ultra ProShares系列和UltraShort ProShares系列股票型指数基金,包括大盘看涨时买入双倍回报的QLD,SSO,DDM或UWM等指数基金,大盘看跌时买入反向双倍回报的QID,SDS,DXD或TWM等指数基金。
举例来说,如果那斯达克100指数在一天之内上涨1%,QQQQ也会同期上涨1%,但QLD会上涨2%,是QQQQ的两倍。而如果那斯达克100指数在某一天下跌1%,QLD则下跌2%,但QID将上涨2%,是指数的反向双倍回报,因此QID适合于大盘看跌时买入(注意是买入,而不是卖空,因为UltraShort ProShares系列的ETF其走势与大盘相反)。你如果想了解更多关于这些双倍回报ETF的情况,请访问这个网址:www.proshares.com
请注意,这种双倍回报的ETF指数基金并不能保证可丁可卯的“双倍”回报,持仓时间越长,就越不可能达到双倍回报。例如,你可能会发现,买入QLD之后的三个月,那斯达克100指数上涨了5%,而QLD只涨了9%,并非10%。但是,嘿,谁又会在意这些呢?只要能高出大盘的回报,哪怕只高出一个百分点,那也比买入QQQQ强,对不对?
有了这些双倍回报的ETF指数基金,业余炒股的普通百姓就完全没有必要花时间研究个股,试图抓一支“大黑马”,能比大盘跑得更快一些。你现在只需要看准大势,跟住大盘,用这些双倍回报的ETF指数基金就能以较低的风险获取较高的回报。

“A security that tracks an index, a commodity or a basket of assets like an index fund, but trades like a stock on an exchange, thus experiencing price changes throughout the day as it is bought and sold.
Because it trades like a stock whose price fluctuates daily, an ETF does not have its net asset value (NAV) calculated every day like a mutual fund does. By owning an ETF, you get the diversification of an index fund as well as the ability to sell short, buy on margin and purchase as little as one share. Another advantage is that the expense ratios for most ETFs are lower than those of the average mutual fund. When buying and selling ETFs, you have to pay the same commission to your broker that you'd pay on any regular order. One of the most widely known ETFs is called the SPDR (Spider), which tracks the S&P 500 index and trades under the symbol SPY. “ |
