 Key features of the Mini-SPX options include —

 CONTRACT SIZE AND ADDED FLEXIBILITY   Mini-SPX options have 1/10th the value of the S&P 500® (SPX) Index options. On Nov. 14 the S&P 500 closed at 1790.62, and the Mini-SPX Index closed at 179.06, its all-time record high daily close (see chart below). The notional value covered by the Mini-SPX options (with a $100 multiplier) was $17,906.   At 1/10th the size of SPX options, Mini-SPX options provide added flexibility. For example, if an investor is looking to hedge $18,000 to $150,000 of broad U.S. stock market exposure, Mini-SPX options may be helpful to investors as they work to achieve a specific desired exposure.

 PM-SETTLEMENT   XSP options now have PM settlement.  PM settlement aligns with single-stock options and ETF options.  PM settlement is preferred by many investors, including those with end-of-day reporting needs.  PM settlement gives investors the ability to trade in and out of positions on the third Fridays.   The last trading day for the standard XSP options generally is on the third Friday of the expiration month.


 ·         Like SPX and most other index options, and unlike SPY and other ETF options

·         No risk of early assignment and loss of dividends, no portfolio disruption on assignment,

·         CBOE Circulars (RG99-09 and RG00-171) allow SPX options to be written on a “covered” basis against SPY or IVV ETF shares in a margin account, provided the investor’s brokerage firm has such policies in place.


As shown below, the XSP Index has marched upward over the past year.
