On August 21, Nasdaq rose 3.03% in regular trading, trading at $99.215/share, with turnover of $65.54 million.

On the news front, Nasdaq formally announced the launch of its 23-hour continuous trading system on December 6, following SEC approval. Under the new regime, U.S. equity markets will only close for one hour daily (8:00 PM to 9:00 PM Eastern Time) for system clearing and data processing, with trading open the remaining 23 hours. The initiative is expected to significantly expand Nasdaq's trading service revenue and propel U.S. equity markets toward a near-round-the-clock trading model.

The broader Financial Exchanges & Data sector posted strong gains, with Cboe Global Markets up 5.50%, CME Group up 2.25%, Intercontinental Exchange up 1.84%, and S&P Global up 1.12%, reflecting broad-based optimism toward exchange operators benefiting from expanded trading hours and higher anticipated volumes.
