How would 24-hour trading impact Nasdaq’s revenue?

Extended hours could boost transaction-based revenue and attract more listings from global companies seeking to trade during their local daytime, directly lifting Nasdaq’s top line.

Is Nasdaq prepared for round-the-clock operations?

Nasdaq has been investing in technology infrastructure and already offers pre-market and after-hours sessions, making a full 24-hour model a incremental step rather than a complete overhaul.

CBOE

Bullish 🤖 83%

📅 Short-term 🌍 US · Explicit

Cboe Global Markets, a key derivatives and equities exchange, would benefit from increased trading activity during extended hours, particularly in its options and futures products tied to equities.

Catalysts

▲ SEC roundtable in September on 24-hour trading
▲ Cboe’s own efforts to provide near-24-hour trading

Risk Factors

▼ Uncertain regulatory outcome from the roundtable
▼ Intensifying competition from other exchanges

▼ Show FAQ (2) ▲ Hide FAQ

Why is Cboe especially well-positioned for 24-hour trading?

Cboe already operates robust after-hours sessions and has a diverse product suite including options and futures, which could see correlated activity increases if underlying equities trade continuously.

What risks does Cboe face from this initiative?

If the SEC imposes burdensome requirements or if liquidity remains thin, Cboe might incur high costs without proportionate revenue gains. Competitive pressures from Nasdaq and other venues also pose a threat.

LSEG

Bullish 🤖 78%

📅 Short-term 🌍 UK · Explicit

London Stock Exchange Group is actively pursuing longer trading hours to attract international business. A US move to 24-hour trading could accelerate LSEG’s own plans and enhance its global competitiveness.

Catalysts

▲ SEC roundtable may set precedent for global 24-hour trading
▲ LSEG’s existing push to extend trading hours

Risk Factors

▼ Post-Brexit regulatory divergence between UK and EU markets
▼ Lower volumes in Asian time zones limiting the benefit

▼ Show FAQ (2) ▲ Hide FAQ

How does the SEC roundtable affect the London Stock Exchange?

As a global exchange operator, LSEG could see increased investor interest and trading volumes if US markets move to 24-hour trading, pressuring European venues to follow suit and creating a more integrated global trading cycle.

Is LSEG already prepared for 24-hour trading?

LSEG has been investing in technology and market structure reforms; it already offers extended hours for some instruments, and a US shift would likely accelerate its own migration to continuous trading.

A move to 24-hour trading would likely increase overall market liquidity and broaden international participation, modestly supporting the S&P 500 by enhancing price discovery and reducing overnight gaps.

Catalysts

• SEC roundtable in September on 24-hour trading
• Growing exchange initiatives to extend hours

Risk Factors

• Regulatory pushback or delayed implementation
• Fragmented liquidity could increase volatility

▼ Show FAQ (2) ▲ Hide FAQ

Would 24-hour trading boost the S&P 500?

The direct impact is likely neutral to slightly positive, as improved access and liquidity can support valuations long-term, but immediate index movements depend more on corporate earnings and macro data.

How would extended hours affect S&P 500 volatility?

Extended trading could reduce overnight gaps by allowing continuous price adjustment, but thin volumes outside regular hours might temporarily raise volatility during certain periods.

NDX

📅 Short-term 🌍 US ✨ Inferred

The Nasdaq-100, heavily weighted toward tech stocks popular with retail traders, could see increased trading activity in extended hours, marginally improving liquidity and price efficiency.

Catalysts

• SEC roundtable discussing 24-hour equity trading
• Nasdaq’s push for longer hours

Risk Factors

• Tech sector sensitivity to macroeconomic shifts could overshadow extended-hours effect
• Retail participation may concentrate in early extended hours, leaving gaps

▼ Show FAQ (2) ▲ Hide FAQ

Will 24-hour trading benefit the Nasdaq-100 more than other indices?

The Nasdaq-100 may see a slight advantage due to its tech-heavy composition and higher retail interest, but the effect is broadly similar across major US indices.

How does extended hours affect Nasdaq-100 listed companies?

The change directly impacts the trading of shares, not company operations. Indirectly, greater liquidity might lower the cost of capital for Nasdaq-listed firms.
