Mini-SPX Index Options
The Chicago Board Options Exchange (CBOE) introduced Mini-SPX index options (XSP), based on the Standard & Poor's 500 Stock Index, beginning October 25, 2005.
Mini-SPX options are 1/10th the value of CBOE's S&P 500 Index options (SPX), so if the S&P 500 Index is at 1400.00, the Mini-SPX would have a value of 140.0, and notional value covered by the Mini-SPX options (with a $100 multiplier) would be $14,000.
CBOE announced on October 29, 2013 that it plans to list a Mini-SPX Index options (options symbol: XSP) contract with a new PM-settlement feature on Tuesday, November 5.
The XSP Index hit an all-time daily closing high of 176.21 on October 28, 2013.
CBOE Mini-SPX Options Overview

The member must report information as to whether such position is hedged and, if so, a description of the hedge employed. A report must be filed when an account initially meets the aforementioned applicable threshold. Thereafter, a report must be filed for each incremental increase of 25,000 contracts. Reductions in an options position do not need to be reported. However, any significant change to the hedge must be reported.
