The S&P 500 has exhibited elevated volatility through Q1 2026, declining over 7% from early-January peaks near 6,900 to 6,369 on March 27 amid hawkish Federal Reserve signals from the March 17-18 FOMC meeting, persistent inflation pressures via hot PPI prints, and Middle East tensions fueling oil price surges. The index's largest single-day gain remains +2.00% on February 6, while the steepest loss hit -2.07% on January 20; recent trading saw -1.74% on March 26 and -1.67% on March 27, extending a five-week losing streak to six-month lows. With just two trading days left until Q1 closes on March 31, quarter-end rebalancing, any geopolitical flares, and heightened VIX near 27 signal potential for amplified daily swings influencing peak gain or loss outcomes.

The percentage change in the S&P 500 Index (SPX) on a given trading day will be calculated by comparing the official closing price for the S&P 500 Index (SPX) on that day to the official closing price for the S&P 500 Index (SPX) on the previous trading day, as reported by the Wall Street Journal. The previous day’s closing price will be subtracted from the current day’s closing price, and then that difference will be divided by the previous day’s closing price. If the daily percentage change is negative, it will be considered a loss of that percentage in absolute terms.
Daily percentage changes will be rounded to two decimal places away from zero (e.g. a daily percentage gain of 1.995% would be considered 2.00%, and a daily percentage gain of 1.993% would be considered 1.99%)
If any relevant trading day is shortened (for example, due to a market-holiday schedule), the official closing price published for that shortened session will still be used for resolution.
If no official closing price is published for a relevant trading day (for example, due to a trading halt into the close, system issue, or other disruption), this market will use the most recent official price published by the specified resolution source as the effective closing price.
The resolution source for this market will be the Wall Street Journal, specifically the daily CLOSE prices for the S&P 500 Index (SPX) published on the S&P 500 Index (SPX) historical prices page (https://www.wsj.com/market-data/quotes/index/SPX/historical-prices).
