What is After-hours Trading and How to Trade After Hours?

What is after-hours trading?

After-hours trading refers to the extended trading session that takes place after the official closing of a stock exchange. After-hours trading sessions vary by exchange, but they typically extend for a few hours following the official market closing time.

After-hours trading provides market participants with the flexibility to react to news events, corporate earnings reports, and other developments that may affect asset prices after the closing bell. Learn more about pre-market trading and how it works.

Regular trading hours, on the other hand, are the standard, officially designated hours during which a given exchange is open for trading. These hours typically encompass the primary trading session when the majority of trading activity occurs.

The pre-market and after-hours trading sessions are often referred to collectively as the “extended” trading sessions. Together, they allow market participants to buy and sell securities before the official market opening and after the closing bell.

At tastytrade, you have the flexibility of trading before and after standard market hours with stock & ETF orders. tastytrade's extended hours session is 1.5 hours before the open, and four hours after the market closes each trading day. Click here for more information.

How does after-hours trading work?

After-hours trading is essentially an extension of the regular trading hours and provides investors and traders with the opportunity to buy and sell financial instruments outside of the official market operating hours.

Additional details on after-hours trading - and how it works - are highlighted below:

  • Time Period: After-hours trading occurs after the official market closing time and extends for a few hours. The exact duration of after-hours trading can vary depending on the exchange and platform. It typically starts shortly after the market closes and continues for several hours.

  • Participation: After-hours trading is available to certain market participants, including institutional investors, retail traders with access to pre-market trading platforms, and market makers. 

  • Eligible Securities: Not all securities are necessarily available for after-hours trading, and eligibility criteria may vary by exchange or brokerage platform. Generally, stocks with significant trading volumes and liquidity are more likely to be available for after-hours trading.

  • Price Discovery: Prices during after-hours trading are determined by the interaction of buy and sell orders, much like in regular trading hours. However, because of lower trading volume, bid-ask spreads can be wider, and price movements may be more volatile.

  • News Impact: After-hours trading is often driven by news events, such as corporate earnings reports, economic data releases, or geopolitical developments. Traders should stay informed about these events, as they can impact asset prices during after-hours sessions.

  • Liquidity: Liquidity in the after-hours market is generally lower than during regular trading hours. That often there may be fewer participants, and it can be more challenging to execute large orders without significantly impacting prices.

  • Order Types: Traders can typically use various order types during the after-hours session, including market orders and limit orders. However, they should be aware that not all order types available in regular trading hours may be offered in the after-hours market. 

  • Trading Platforms: To participate in the after-hours market, traders often need access to specialized trading platforms or brokerage accounts that support pre-market orders. At tastytrade, you have the flexibility of trading before and after standard market hours with stock & ETF orders. tastytrade's extended hours session is 1.5 hours before the open, and four hours after the market closes each trading day.

  • Extended Hours Trading Risks: The after-hours session carries specific risks, including lower liquidity, potentially wider spreads, and the potential for larger price gaps due to news events. Traders should therefore exercise caution and be aware of these risks when participating in the after-hours market. 

It's important to note that the rules and regulations governing after-hours trading can vary by exchange and region. Traders interested in participating in after-hours trading should check with their brokerage firm, or the specific exchange, for details on available securities, trading hours, and any additional requirements or restrictions.

After-hours trading hours: when does after-hours trading start and end?

The after-hours trading session typically begins shortly after the official market closing time. Most U.S. stock exchanges ring the closing bell at 4:00 PM Eastern Time (ET). After-hours trading can commence within minutes or shortly after the regular market closes, allowing investors and traders to continue trading beyond the official closing bell.

The exact start time of the after-hours session can vary slightly between different exchanges and trading platforms. While some platforms may begin after-hours trading immediately at 4:00 PM ET, others may start a bit later, usually within the next half-hour or so.

The timing for the after-hours sessions at the New York Stock Exchange and the Nasdaq Stock Market are highlighted below:

How to trade after-hours

Trading during the extended sessions (pre-market or after-hours) can differ from the regular trading session in several notable ways. One significant difference is the lower liquidity observed during extended hours. With fewer market participants engaged, trading volumes tend to be lower, resulting in wider bid-ask spreads and reduced order flow. This can make it more challenging to execute large orders without impacting prices significantly.

Another key distinction is the increased volatility that often characterizes extended trading hours. Price swings can be more pronounced during this time, especially in response to breaking news or significant events that occur outside regular hours. Traders should be prepared for rapid fluctuations and the potential for abrupt changes in market sentiment.

Additionally, not all securities are available for trading during extended hours, as eligibility criteria may vary by exchange or platform. This means that traders need to check which specific stocks, ETFs, or options contracts are accessible during these sessions. Moreover, some order types commonly used in regular trading hours may not be available during extended hours, limiting traders to using market orders and limit orders.

Extended trading sessions also tend to attract a different set of participants, including more experienced traders and institutional investors. Retail investors may therefore find themselves trading alongside professional traders who are more active during these hours, potentially altering the overall trading dynamic. Investors and traders should be aware of these differences and adapt their strategies, risk management, and expectations as necessary when participating in extended trading hours.

Some of the key considerations for pre-market and after-hours trading sessions are detailed below: 

  • Stay Informed: Be well-informed about news and events that could impact the stocks or securities you plan to trade. Earnings reports, economic data releases, and company announcements can have a significant effect on prices.

  • Understand the Risks: Recognize that pre-market and after-hours trading can be riskier due to reduced liquidity. Prices can be more erratic, and spreads wider. Only trade during these sessions if you have a clear strategy and risk management plan in place.

  • Consider Using Limit Orders: In illiquid markets, use limit orders to specify the price at which you are willing to buy or sell. Avoid market orders, which can result in unfavorable fills due to price gaps.

  • Monitor Market Depth: Keep an eye on the order book and market depth to gauge demand and supply levels. This information can help you anticipate potential price movements.

  • Consider Setting Stop-Loss Orders: Implement stop-loss orders to limit potential losses. Determine your risk tolerance and set stop-loss levels accordingly.

  • Watch for Overnight Gaps: Overnight gaps, where the price at the open differs significantly from the previous day's close, are common in extended trading sessions. Be prepared for such gaps and have a plan in place to manage them.

  • Consider Starting with Smaller Positions: If you are new to pre-market and after-hours trading, consider starting with smaller positions until you gain experience and confidence.

  • Focus on High Liquidity Listings: Focus on stocks or securities that are actively traded during extended hours. Highly liquid assets tend to have narrower spreads and are generally easier to trade.

  • Consider Paper Trading: If you are unsure about your pre-market and after-hours trading approach, consider paper trading (e.g. simulated trading without real money) to practice and develop your strategies.

  • Review and Learn: After each extended trading session, review your trades and assess what worked and what didn't. Learn from your experiences to improve your approach. 

Some of the common strategies utilized during the extended trading sessions are highlighted below: 

  • Gap Trading: Taking advantage of price gaps caused by overnight news or events.

  • Earnings Plays: Trading based on earnings reports released before the market opens, or after the market closes. 

  • News Breakouts/Momentum: Identifying and trading stocks that react strongly to breaking news during the pre-market and/or after-hours sessions. 

  • Scalping: Scalping opportunities may sometimes present themselves during the extended trading sessions. 

Benefits and risks of trading in the extended sessions

Extended trading sessions, which include both pre-market and after-hours trading, offer both benefits and risks to market participants that are active during these periods. 

Some of the key benefits and risks associated with the extended trading sessions are highlighted below.

Benefits of after-hours trading

  • React to News: Extended trading hours allow market participants to react to breaking news and corporate earnings reports that are released outside regular trading hours. This can provide an opportunity to adjust positions and capitalize on price movements driven by significant events.

  • Flexibility: Extended hours trading provides flexibility for traders with different schedules. Those who cannot participate in regular trading hours due to work or other commitments can engage in extended sessions to manage their portfolios.

  • Global Trading: Extended trading allows market participants to respond to events and developments that occur in international markets while their local markets are closed. This global perspective can be valuable for international investors.

  • Opportunity for Gap Moves: Price gaps can occur between the previous day's closing price and the opening price of the next regular session. Traders can take advantage of these gaps by participating in extended sessions to capture potential profits.

Risks of after-hours trading

  • Lower Liquidity: Extended trading sessions typically have lower trading volumes and reduced liquidity compared to regular hours. This can result in wider bid-ask spreads and make it more challenging to execute large orders without impacting prices.

  • Higher Volatility: The reduced number of market participants during extended hours can lead to increased volatility, particularly in response to news events. Rapid and unpredictable price movements can pose risks to traders.

  • Limited Securities: Not all securities are available for trading during extended hours, and eligibility criteria may vary by exchange or platform. Traders need to be aware of which assets are accessible.

  • Limited Order Types: Some order types that are commonly used during regular hours may not be available during extended hours. Traders may be restricted to using market orders and limit orders.

  • Professional Traders: Extended hours often attract more experienced traders and institutions, potentially altering the overall trading dynamic. Retail investors may find themselves trading alongside professional traders with a different level of expertise.

  • Gap Moves: Price gaps can occur between extended trading sessions and regular trading sessions. These gaps may represent an increased risk for market participants that are active during the extended sessions.

After-hours trading summed up

After-hours trading refers to the extended trading session that takes place after the official closing of a stock exchange. After-hours trading sessions vary by exchange, but they typically extend for a few hours following the official market closing time.

After-hours trading provides market participants with the flexibility to react to news events, corporate earnings reports, and other developments that may affect asset prices after the closing bell.

The after-hours trading session typically begins shortly after the official market closing time. Most U.S. stock exchanges ring the closing bell at 4:00 PM Eastern Time (ET).

During after-hours trading, liquidity tends to be lower, and trading volumes reduced as compared to regular hours. This can result in wider bid-ask spreads and limited order flow, making it important for traders to use limit orders and exercise caution when executing trades. The lower liquidity can also lead to increased price volatility, especially in response to news events, making risk management a critical aspect of pre-market trading.

Not all securities are available for trading during after-hours sessions, and eligibility criteria may vary by exchange or platform. Traders should check which specific assets are accessible during these sessions. Additionally, some order types commonly used during regular hours may not be available during pre-market trading, which further emphasizes the need for traders to adapt their strategies.

  • Gap Trading: Taking advantage of price gaps caused by overnight news or events.

  • Earnings Plays: Trading based on earnings reports released before the market opens, or after the market closes. 

  • News Breakouts/Momentum: Identifying and trading stocks that react strongly to breaking news during the pre-market session.

  • Scalping: Identifying and profiting from small price movements in assets over a very brief time frame. Scalping opportunities may sometimes present themselves during the extended trading sessions. 

In general, after-hours trading sessions offer a window of opportunity for those seeking to stay informed and nimble in the face of financial developments that occur outside of regular trading hours. These sessions cater to investors and traders looking to react to news, earnings reports, and global events, while also allowing for a more flexible trading schedule. 

But investors and traders active in the after-hours sessions should be mindful of the lower liquidity, heightened volatility, and potential cost implications that come with trading in the extended sessions, and should prepare their strategic approach and risk management plan before joining these sessions.
