A concise weekly overview of the U.S. equities and derivatives markets

Last week (August 16 – August 20), each of the major U.S. equity indices was lower, as “reopening” companies (airlines, leisure, etc.) underperformed the “stay at home” stocks. European and Chinese equities sold off harder than U.S. stocks. In terms of sector performance, Energy continues to lag and the Energy Select Index fell 7.25%. Materials declined by 3.3%. Health Care was higher by 1.9% and Utilities climbed 1.7%. In short, defensive stocks held up, while more cyclical names came under pressure. The Dollar Index was strong last week on the heels of the Federal Open Market Committee (FOMC) meeting minutes release.

The S&P 500 Index lost approximately 3% relative to its high water mark, but ended the week less than 2% off highs. 

Cboe’s Quote Depletion Protection (QDP) is a patent-pending, optional instruction that market participants can use in conjunction with Midpoint Discretionary Orders (MDOs) on Cboe’s EDGX® and EDGA® Equities Exchanges. When activated, QDP disables an MDO’s discretionary range for a short period when the exchange’s quote indicates the price may move in a manner that could result in a more aggressive execution price. Since Cboe launched QDP in June 2020, our North American Equities Execution Consulting Team has monitored how market participants appear to use it and has continued to evaluate potential enhancements. Cboe believes QDP remains a beneficial tool for market participants, especially those using certain strategies.
