PowerShares QQQ has benefitted from the Nasdaq-100 Index’s outperformance versus main stock benchmarks recently, but its route is closely linked to tech giant Apple Inc., which includes one-fifth with the exchange-traded fund’s assets.
The Nasdaq-100 was in a position to escape its summer time buying and selling array during September’s rally, unlike the S&P 500 Index (SPX 1,161, +23.72, +2.09%) and the Dow Jones Industrial Average (DJIA 10,945, +193.45, +1.80%) . Stocks jumped Tuesday after the Bank of Japan announced plans to dampen the yen’s rise, and the Nasdaq basket again led the way.
