NEW YORK (TheStreet) -- Volatility among the 30 components of the PHLX Semiconductor Index, also known as the SOX, creates investment opportunities in the stocks that are outperforming the index.

The biggest year-to-date winners are Avago Technologies  (AVGO) - Get Report and Skyworks Solutions (SWKS) - Get Report. Those stocks were also the largest gainers of 2014 as the two companies benefited from supplying computer chips for Apple (AAPL) - Get Report products. Entering the list of year-to-date winners are Marvel Technology (MRVL) - Get Report, Nvidia (NVDA) - Get Report and Texas Instruments (TXN) - Get Report. This post will look at those five stocks, plus Intel (INTC) - Get Report and Micron Technology (MU) - Get Report, which are two widely held semiconductor stocks.

Let's take a look at the daily and weekly charts for the SOX first.
