Trader sentiment for S&P 500 single-day percentage gains and losses in the first quarter reflects low prevailing volatility, with the VIX index hovering around 13-15 amid steady economic expansion and anticipated Federal Reserve rate cuts. Recent sessions have seen modest swings—largest Q1 gain near 1.5% following softer-than-expected January CPI data, offset by a 1.2% drop on hawkish FOMC minutes—pricing in limited tail risks absent major shocks. Key drivers include monthly nonfarm payrolls (next March 7), CPI releases (March 12), and the March 18-19 FOMC meeting, where dot plot updates could spark 2%+ moves if inflation reacceleration or labor strength alters rate cut odds from four to two in 2025. Earnings from megacap tech firms closing Q4 reports also loom as catalysts.

This market will resolve to “Yes” if the price of the S&P 500 Index (SPX) increases by at least the listed percentage on any single trading day between January 14 and March 31, 2026. Otherwise, this market will resolve to “No”.
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).This market will resolve to “Yes” if the price of the S&P 500 Index (SPX) increases by at least the listed percentage on any single trading day between January 14 and March 31, 2026.

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 loss of 1.995% would be considered 2.00%, and a daily percentage loss 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).This market will resolve to “Yes” if the price of the S&P 500 Index (SPX) decreases by at least the listed percentage on any single trading day between January 14 and March 31, 2026. Otherwise, this market will resolve to “No”.

0x65070BE91...Trader sentiment for S&P 500 single-day percentage gains and losses in the first quarter reflects low prevailing volatility, with the VIX index hovering around 13-15 amid steady economic expansion and anticipated Federal Reserve rate cuts. Recent sessions have seen modest swings—largest Q1 gain near 1.5% following softer-than-expected January CPI data, offset by a 1.2% drop on hawkish FOMC minutes—pricing in limited tail risks absent major shocks. Key drivers include monthly nonfarm payrolls (next March 7), CPI releases (March 12), and the March 18-19 FOMC meeting, where dot plot updates could spark 2%+ moves if inflation reacceleration or labor strength alters rate cut odds from four to two in 2025. Earnings from megacap tech firms closing Q4 reports also loom as catalysts.
