What are the new indexes?

The PHLX Semiconductor 20% Daily Covered Call Index (SOX20DCI) tracks the performance of a systematic at-the-money 20% partial coverage short call strategy. The strategy aims to provide specific coverage to the underlying PHLX Semiconductor Sector Total Return Index (XSOX) using Nasdaq-100 Index® (NDX®) short call options, typically with one day to expiration.

The strategy measures the performance of only the short call portion of the PHLX Semiconductor 20% Daily Covered Call Index (SOX20DCI). The Call Only Index includes a cash account but does not include a long underlying PHLX Semiconductor Sector Total Return Index position.
