What to Watch Tomorrow — August 13, 2026
- Economic Data: Watch for any scheduled releases of jobless claims, PPI, or retail sales data that may hit the tape before the open. The 10-year Treasury yield at 4.68% will be a key level to monitor for further moves.
- Earnings: With the AI complex in focus, any late-day reports from technology or AI-infrastructure names could drive extended-hours volatility. Monitor NBIS, CRWV, and QNT for continued momentum.
- Commodities: Gold's 2.43% surge to $4,489.60 is a major move; watch whether that bid continues or fades. WTI crude at $82.25 will also be watched for supply headlines.
- Index Levels: The S&P 500 at 7,748.50 and the Nasdaq at 26,588.49 are near record territory. The Russell 2000's 21.42% YTD gain suggests continued small-cap leadership; watch for any rotation out of technology into lagging sectors.
