Technology exchange traded funds are once again receiving a boost from Apple (NasdaqGS: AAPL) shares, which broke through $500 on Monday.

The technology sector represents innovation and economic growth for investors, and has been able to outpace the S&P 500 in 2012. As the momentum continues, leading tech company Apple has investors focused on the sector aggressively.
