| Exchange circuit breaker rules for domestic stock index futures call for a quarterly re-assessment of price limits based on prevailing market prices. Limits are calculated quarterly at the close of business on the day preceding the commencement of a new calendar quarter. Thus, new limits became effective on Monday, April 1st. (Actually, the revisions went into force on Sunday March 31st with the commencement of Electronic Trading Hours [ETH] for trades dated April 1st.) The revised limits shall be applicable throughout the 2nd calendar quarter.

Exchange rules call for the limits to be re-calculated quarterly at the close of business on the day preceding the commencement of a new calendar quarter. Note that stock index price limits are generally revised downwards from the limits that were in force during the previous calendar quarter. The Exchange�s circuit breakers are re-assessed quarterly rather than established at fixed levels insofar as fixed limits are not responsive to on-going market fluctuations. CME Rules are designed to coordinate with circuit breaker provisions as applied by the New York Stock Exchange (NYSE). Please contact Brett Vietemer at (312) 930-3394, if you have any questions. |
