QQQQ改變了遊戲規則

QQQQ改變了遊戲規則

伴隨著SP500采取以流通市值計算的方法代替總市值，QQQQ也改變了遊戲規則。並且，QQQQ100的計算權重被視作Nasdaq committee的property，不再免費公開,subscriber fee is $10K annually.所以無法計算其影響。

根據：

http://www.nasdaq.com/asp/indexshares.asp?symbol=QQQQ

增加了QCOM/AAPL/EBAY/SBUX 的權重，降低了MSFT/CSCO/GOOG/AMGN/INTC/ORCL的權重。其目的顯然是要保持和增強QQQQ的活躍幅度。

Naz隻玩20股的策略不變，但跟蹤對象的偏重要相應變化。所以要在每個quarter末，check top 10 update:
