Rising Treasury yields, with the 10-year note reaching its highest level in a year, combined with tech-sector weakness and elevated oil prices amid Middle East tensions, pressured the S&P 500 and SPY during the week of May 18. The benchmark index traded near 7,400–7,450 while SPY fluctuated between roughly 733 and 749, closing the period around 7,440–7,450 after mixed daily moves that included a Monday dip below 7,405. Strong first-quarter earnings beats and resilient corporate margins supported the broader advance to fresh highs earlier in May, yet forward-looking concerns over inflation persistence and monetary policy kept implied volatility elevated. Key upcoming releases, including FOMC minutes and additional inflation data, could further shape near-term equity pricing.

Only prices achieved during the regular trading hours of the primary exchange on which the listed security trades (typically 9:30 AM – 4:00 PM ET) will be considered. Prices occurring during pre-market or after-hours trading will not qualify.
Prices will be used exactly as published by Pyth, without rounding.
In the event of a stock split, reverse stock split, or similar corporate action affecting the listed company during the listed time frame, this market will resolve based on split-adjusted prices as displayed on Pyth.
The target price will be adjusted proportionally to reflect any stock splits. Resolution will be based on the historical price data as shown on Pyth after any adjustments have been applied.
The resolution source for this market is Pyth — specifically, the S&P 500 (SPY) "High" prices available at https://pythdata.app/explore/Equity.US.SPY%2FUSD, with the chart settings configured for 1-minute candles.
Historical 1-minute candles may be accessed by appending a Unix timestamp (seconds) to the Pyth chart URL using the "t=" parameter. Any timestamp within the listed market time frame may be used to view the relevant candle data (e.g., https://pythdata.app/explore/Equity.US.SPY%2FUSD?t=1773432000)
If the relevant Pyth data is unavailable due to a system outage, data failure, or other technical disruption that prevents verification of the required 1-minute candle data, the official daily high price published by the primary exchange on which the listed security trades will be used to determine whether the listed price was reached during the applicable trading session.
