Understanding extended trading

What is extended trading?

Extended trading, also known as pre-market and after-hours trading, takes place beyond the typical trading hours of major stock exchanges like the New York Stock Exchange (NYSE). while the regular trading hours run from 9:30 a.m. to 4:00 p.m. EST, pre-market trading spans from 4:00 a.m. to 9:30 a.m. EST, and after-hours trading operates between 4:00 p.m. and 8:00 p.m. EST.

How extended trading works

Extended trading has been revolutionized by Electronic Communication Networks (ECNs), computerized systems that automatically match buy and sell orders for securities. It allows investors to act swiftly on breaking news and events, even when the exchange is closed. The most active extended trading times are typically between 8:00 a.m. and 9:30 a.m. EST, with some trading continuing until 8:00 p.m. However, not all securities are eligible for extended trading, with limitations on specific types like Reg NMS securities.

Broker rules and market variations

The rules governing extended trading sessions are set by brokerage firms, and these rules can significantly differ from those applied during regular trading hours. The eligibility of securities for extended trading also varies, with over-the-counter securities, certain funds, select options, and other markets sometimes excluded from extended hours.

Extended trading risks

Challenges in extended trading

Extended trading presents several unique risks, as highlighted by the U.S. Securities and Exchange Commission (SEC):
Limited liquidity: Extended hours often witness lower trading volumes compared to regular hours, which can make executing trades challenging. Some stocks may not trade at all during extended hours.
Large spreads: Reduced trading volumes often translate into wider bid-ask spreads, which can adversely affect market prices and make it harder to execute orders at favorable prices.
Increased volatility: Lower trading volumes can lead to greater price volatility, resulting in wider bid-ask spreads. Prices may experience significant fluctuations in a short time.
Uncertain prices: Prices during extended hours may not closely align with those during regular trading hours, leading to uncertainty for investors.
Professional competition: Extended trading often attracts large institutional investors, such as mutual funds, which may have access to more resources and information.

Example of extended trading

To illustrate extended trading’s dynamics, let’s examine an example:
[Insert example or charts if necessary]
After 4:00 p.m., trading volume typically decreases, resulting in price bars that may appear as dots due to minimal transactions. Gaps between these dots can occur as prices change without actual transactions. The last transaction of the evening may happen around 7:55 p.m., with trading resuming at 7:28 a.m. the following day.

When can investors benefit from extended trading?

Investors and traders can benefit from extended trading by capitalizing on immediate reactions to news and events outside of regular exchange hours. For instance, if a company reports disappointing earnings after hours, traders can exit positions before the market reopens.

Where can investors trade during extended hours?

Extended trading takes place on alternative trading systems operated by broker-dealers, exchanges, and other trading centers. However, it’s crucial to note that not all markets or securities are available for extended hours trading.

Understanding unlinked markets

An important consideration is that extended hours trading systems are not linked. The price of a stock displayed on one trading system may differ from the price displayed on another system, potentially leading to price disparities and trading complexities.

The bottom line

Extended trading allows investors to participate in electronic marketplaces outside regular exchange hours, which typically run from 9:30 a.m. to 4:00 p.m. EST. While it offers opportunities, it also comes with risks, including price volatility and wider quote spreads. Most brokers require traders to enter limit orders during extended trading sessions, ensuring control over execution prices.
