There is only one Qubes fund, and it was one of three largest funds available. This fund tracks the NASDAQ-100. Like the other major ETFs, this fund is referred to by its brand name. A join venture of NASDAQ and AMEX issues shares of Qubes.
The NASDAQ-100 includes the 100 largest, non-financial, companies traded at the NASDAQ.
Shares of Qubes are traded at the AMEX and their ticker symbol is QQQQ. Their asset value is calculated this way: One dollar times one-fortieth of the NASDAQ-100. For example, if the NASDAQ-100 is at 800 points, the asset value of a share of Qubes is 20 dollars.
By the end of 2007, trading volume on Qubes had reached more than 70-120 million shares a day. This fact places Qubes as the most heavily traded ETF on the market, alongside Spiders and Diamonds.
