How to Trade Stocks After Hours

Trading stocks outside standard market hours, known as after-hours trading, allows investors to execute transactions when major financial markets are typically closed. This provides a window for investors to react to news and events that unfold beyond the regular trading day.

Fundamentals of After-Hours Trading

Extended hours trading includes pre-market and after-market sessions, occurring outside the typical 9:30 a.m. to 4:00 p.m. ET trading window for major U.S. stock exchanges like the NYSE and Nasdaq. Pre-market trading usually begins at 4:00 a.m. ET and extends until market open. After-hours trading typically starts at 4:00 p.m. ET and can continue until around 8:00 p.m. ET, though specific times vary by brokerage.

Trading during extended sessions primarily occurs through Electronic Communication Networks (ECNs). ECNs are computerized systems that automatically match buy and sell orders directly between market participants, bypassing traditional market makers. They display bid and ask quotes, facilitating rapid execution by connecting buyers and sellers. ECNs operate by internally matching limit orders and often charge a small per-share transaction fee.

After-hours trading has distinct market characteristics compared to regular trading hours. Lower liquidity is a notable feature, meaning fewer buyers and sellers are active. This reduced participation can make trades challenging, as a counterparty might not be readily available. Lower liquidity often results in wider bid-ask spreads, the difference between the highest price a buyer will pay and the lowest price a seller will accept.

Wider spreads can influence the execution price, potentially leading to less favorable outcomes. Limited trading volume during extended hours contributes to increased price volatility. News announcements, such as earnings reports released after market close, can cause significant price swings with fewer participants to absorb the impact. This environment can result in rapid price movements for securities.

Brokerage Access and Requirements

Engaging in after-hours trading requires a standard brokerage account. Investors must confirm their chosen brokerage firm offers extended hours trading capabilities, as not all platforms provide this service. Many prominent brokerages facilitate after-hours access, but specific rules and features can differ.

To enable extended hours trading, investors often need to activate specific settings or agree to additional terms within their brokerage account. This process involves acknowledging the unique characteristics and implications of trading outside regular market hours. Brokerages are generally required by FINRA to provide risk disclosure statements to customers engaging in extended hours trading. These disclosures outline considerations such as lower liquidity, higher volatility, and wider spreads.

Extended hours trading functionality is typically available across various platform types, including desktop, web, and mobile apps. When selecting a platform, investors should look for clear indicators of extended hours pricing and the ability to easily toggle on this feature. Some platforms may also offer specialized tools or watchlists to identify eligible securities.

Before attempting an after-hours trade, investors should ensure their account settings are configured correctly. This might involve reviewing or signing an extended hours trading agreement to confirm understanding of the terms. Accessing real-time quotes for extended hours is also practical, as these quotes reflect prices available through the specific ECNs the brokerage utilizes.

Placing After-Hours Orders

Once a brokerage account is configured for extended hours, placing an after-hours order generally begins by navigating to the trading interface within the platform. This interface is often similar to the one used for regular market hours, but with specific options for extended sessions. Investors then search for and select the stock or asset they intend to trade.

The type of order placed is crucial for after-hours trading. Due to lower liquidity and increased volatility in extended sessions, limit orders are typically the only viable or recommended order type. A limit order instructs the brokerage to buy or sell a security at a specified price or better, providing control over the execution price. This contrasts with market orders, which aim for immediate execution at the current market price but can result in unexpected prices during volatile periods.

To place a limit order, investors select “Limit Order” from the available order types and input the precise price at which they are willing to buy or sell shares. For a buy limit order, this means the order will only execute at the specified price or lower, while a sell limit order will execute at the specified price or higher. This mechanism helps to mitigate the impact of wider bid-ask spreads and potential price fluctuations common in after-hours environments.

Another important consideration is the Time-in-Force (TIF) option, which dictates how long an order remains active. Common TIF options relevant to extended hours include “Good Till Cancelled (GTC)” or “Extended Hours (EXT)”. An EXT order is valid only for the specific extended hours session and will expire if not filled. A GTC order can remain active for a longer period, sometimes up to 180 days, unless executed or manually canceled.

After selecting the desired TIF, investors review all order details—including the stock, quantity, limit price, and TIF—before submitting the order. Following submission, the platform typically provides a confirmation message, and investors can monitor the order’s status to track its execution.
