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

Last week (September 6 – September 10), major U.S. equity markets retreated during the Labor Day shortened week. The Nasdaq 100 fell 1.36% and the small-cap Russell 2000 Index declined 2.4%. In terms of S&P 500 Index sector performance, Heath Care lagged, declining 2.4% week-over-week. Industrials declined 2.0% and Consumer Discretionary eked out small gains. Amazon and Tesla are the two largest constituents in the sector, and they were relative standouts. Markets have had a more defensive tone for the better part of two months, which is best illustrated by the relative strength in Utilities. Growth proxies like Oil and Copper are both about 10% off 2021 highs.

Economists have scaled back expectations for third quarter growth. Slumping consumer sentiment, which has been reflected in retail sales data and supply chain issues, is considered the culprit. The S&P 500 Index is now nearly a year removed from the last 5% peak-to-trough decline. Implied volatility levels for the index popped significantly last week, despite realized volatility levels remaining muted. Time will tell whether the options market is correct in anticipating some turbulence or if the current fears will quickly subside.
