Underlying Futures Contract: CBOT 30-year US Treasury Bond (US)
Depth: Continuous Futures Contract #1 (US1)
Roll Date: Roll on First Day of Delivery Month. Contracts roll on the first day of the delivery month of the expiring or front contract. If the front contract expires before the first day of the deliverty month, then contracts roll on the expiry date instead.
Price Adjustment: Calendar Weighted Method. The price gap between consecutive contracts is smoothed by following a weighted-average process. The continuous contract gradually shifts from representing 100% front and 0% back weighting, to 0% front and 100% back weighting, over a period of 5 days. This price adjustment corresponds to a mechanical roll strategy wherein the trader rolls 20% of the position every day, for 4 days before the roll date.
Methodology: To read more about the Stevens roll date and price adjustment methodology, see the Documentation tab on the Stevens Continuous Futures database home page.
Contract Size: One U.S. Treasury bond having a face value at maturity of $100,000.
Deliverable Good: U.S. Treasury bonds that, if callable, are not callable for at least 15 years from the first day of the delivery month or, if not callable, have a remaining term to maturity of at least 15 years from the first day of the delivery month. Note: Beginning with the March 2011 expiry, the deliverable grade for T-Bond futures will be bonds with remaining maturity of at least 15 years, but less than 25 years, from the first day of the delivery month. The invoice price equals the futures settlement price times a conversion factor, plus accrued interest. The conversion factor is the price of the delivered bond ($1 par value) to yield 6 percent.
