Index Insights: September 2024

September 2024 index performance was generally positive for broad-based U.S. indices. The S&P 500 lifted 2% to close at all-time highs of 5,762.48, which is nearly 992 points, or 20.7%, above the 2023 closing level of 4769.83. Small caps underperformed, with the Russell 2000 Index up about eight points, or less than half a percent to close at 2,229.97, putting the index up nearly 10% year-to-date (YTD). Notably, implied volatility was higher this month, with the Cboe Volatility Index^® (VIX Index^®) lifting from 15 to 16.72 as premiums increased a bit on geopolitical concerns and the looming U.S. election. The slight lift for equities led to gains in both call-write and put-write indices on the S&P 500, Russell 2000, MSCI and fixed income segments, which perform well in sideways markets with relatively muted realized volatility.

The Cboe VIX Tail Hedge Index (VXTH) tracks the performance of a hypothetical portfolio that:

• Buys and holds the performance of the S&P 500 index (the total return index, with dividends reinvested), and
• Buys one-month 30-delta call options on the Cboe Volatility Index (VIX). New VIX calls are purchased monthly, a procedure known as the "roll." The weight of the VIX calls in the portfolio varies at each roll and depends on the forward value of VIX, an indicator for the perceived probability of a "swan event."
• The weights are determined according to this schedule and the weights applied at a particular roll date can be seen by opening the VXTH Monthly Roll Spreadsheet.
