Tech stocks and broader market indices often moving in different directions. Which index will show better performance on July 15?

Market Dates

• Market Closing: The market closes on July 15, 2025, at 9:30 AM EDT
• Measurement Period: July 15, 2025 (daily performance)
• Resolution Time: July 15, 2025, 4:00 PM EDT (after market close)

Resolution Criteria

The market resolves to:

• S&P 500 if the S&P 500's percentage change for the day is higher than the Nasdaq's percentage change
• Nasdaq if the Nasdaq's percentage change for the day is higher than the S&P 500's percentage change

Performance will be calculated as:

• Percentage change = ((Closing price - Previous day's closing price) / Previous day's closing price) × 100
• The index with the higher percentage change (or smaller loss) will be considered the winner
• In case of exactly equal performance, the market will be canceled

Resolution

The outcome will be determined using the official closing prices from Investing.com, comparing the percentage change of both indices. The calculation will use the standard closing prices for both indices.

Data will be sourced from:

• S&P 500: https://www.investing.com/indices/us-spx-500-historical-data
• Nasdaq: https://www.investing.com/indices/nasdaq-composite-historical-data

Cancellation Conditions

The market will be canceled if:

• Trading is suspended or interrupted for either index
• The official data source is unavailable or shows conflicting information
• A major market disruption affects the normal trading or closing prices
• Technical issues prevent accurate calculation of the performance
• Both indices show exactly the same percentage change

In the event of cancellation, participants may claim their stakes at the market value of their open positions at the time of cancellation. This could result in a profit or a loss, depending on the price of their outstanding shares.
