It is a subset of the Russell 3000® Index and includes approximately 1000 of the largest securities based on a combination of their market cap and current index membership. The Russell 1000 represents approximately 92% of the U.S. market. The Russell 1000 Index is constructed to provide a comprehensive and unbiased barometer for the large-cap segment and is completely reconstituted annually to ensure new and growing equities are reflected.
Premium Quotation
Stated in points, one point equals $100. Minimum tick for series trading below $3 is 0.05 ($5.00); above $3 is 0.10 ($10.00).
Strike (Exercise) Prices
In-, at- and out-of-the-money strike prices are initially listed. New strikes can be added as the underlying trades through the highest and lowest strike price available.
Strike Price Intervals
Strike prices may be listed with a minimum interval of 2.5 points if the strike price is less than 200. When the strike price is 200 or above, strike price intervals will be no less than 5 points.
Expiration Months
Up to 6 near-term months. In addition, the Exchange may list up to 10 RUI LEAPS expiration months that expire from 12 to 60 months from date of issuance.
Expiration Date
The third Friday of the expiration month.
Exercise Style
European and A.M.-settled - RUI options generally may be exercised only on the Expiration Date.
Last Trading Day
Trading in expiring RUI options will ordinarily cease on the business day (usually a Thursday) preceding the day on which the exercise-settlement value is calculated.
Settlement of Option Exercise
Exercise will result in delivery of cash on the business day following expiration. The exercise settlement value (RIR) is calculated using the first (opening) reported sales price in the primary market of each component security on the expiration date (usually a Friday). The exercise-settlement amount is equal to the difference between the exercise-settlement value and the exercise price of the option, multiplied by $100.
Position and Exercise Limits
The position limit is 50,000 contracts on the same side of the market, with no more than 30,000 contracts in the near term expiration month and the exercise limit is 30,000 contracts.
Customer Strategy -Based Margin
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 Rules 12.3(h) and 12.10.
Customer Portfolio Margin
RUI options are eligible for a portfolio margin account. RUI options are accommodated in the High-Capitalization Broad-Based Index Product Group (9), with a 90% offset with the other classes contained in that Product Group. The magnitude of the valuation point range under Cboe Rule 12.4 (Portfolio Margin) for RUI options held in a portfolio margin account is -8%/+6%. The current (spot or cash) RUI index value will be used to calculate theoretical gains and losses for RUI options. Additional margin may be required pursuant to Exchange Rule 12.10.
