The Mini-SPX Index, based on 1/10th the value of the Standard & Poor's 500 Index (SPX). The Standard & Poor's 500 Index is a capitalization-weighted index of 500 stocks from a broad range of industries. The component stocks are weighted according to the total market value of their outstanding "free float" shares.
Strike Price Intervals:
Generally, $1 or greater where the strike price is $200 or less and $5.00 or greater where the strike price is greater than $200.
Strike (Exercise) Prices:
In-, at- and out-of-the-money strike prices are initially listed. New strikes can be added as the index moves up or down.
Stated in decimals. One point equals $100. The minimum tick for XSP options is 0.01 ($1.00) for all series, including LEAPS.
European - Mini-SPX Index options generally may be exercised only on the expiration date.
Last Trading Days:
Trading in "standard" (i.e., 3rd Friday) XSP options will ordinarily cease on the business day (usually a Friday) preceding the expiration date. Trading in all other XSP options will ordinarily cease on the expiration date.
The third Friday of the expiration month.
CBOE may list up to six expiration months of XSP options at one time. End-of-Week (i.e., "Weekly") options and LEAPS may also be listed.
Settlement of Option Exercise:
Exercise will result in delivery of cash on the business day following expiration. The exercise settlement value, XSP, is one-tenth (1/10th) the official closing price of the S&P 500 Index as reported by Standard & Poor's on the last trading day of the expiring series. The exercise settlement amount is equal to the difference between the exercise-settlement value and the exercise price of the option, multiplied by $100.
No position and exercise limits are in effect. Each Trading Permit Holder (other than a market-maker) or TPH organization that maintains an end of day aggregate position in excess of 100,000 contracts in SPX and Mini-SPX (i.e., XSP and XSPam; 10 Mini-SPX options equal 1 SPX full value contract) for its proprietary account or for the account of a customer, shall report certain information to the Department of Market Regulation. The TPH must report information as to whether such position is hedged and, if so, a description of the hedge employed e.g. stock portfolio current market value, other stock index option positions, stock index futures positions, options on stock index futures; and for customer accounts, provide the account name, account number and tax ID or social security number. Thereafter, if the position is maintained at or above the reporting threshold, a subsequent report is required on Monday following expiration and when any change to the hedge results in the position being either unhedged or only partially hedged. Reductions below these thresholds do not need to be reported.
Purchases of puts or calls with 9 months or less until expiration must be paid for in full. Writers of uncovered puts or calls must deposit / maintain 100% of the option proceeds* plus 15% of the aggregate contract value (current index level x $100) minus the amount by which the option is out-of-the-money, if any, subject to a minimum for calls of option proceeds* plus 10% of the aggregate contract value and a minimum for puts of option proceeds* plus 10% of the aggregate exercise price amount. (*For calculating maintenance margin, use option current market value instead of option proceeds.) Additional margin may be required pursuant to Exchange Rule 12.10.
