How to Buy Stocks After Hours

Extended hours trading allows individuals to buy and sell stocks outside the standard market schedule. This provides a way to react quickly to significant news or events that often occur when regular exchanges are closed. It also offers convenience for those whose schedules do not align with traditional trading times. Understanding the mechanics and characteristics of this market segment is important for anyone considering engaging in such activities.

Understanding Extended Hours Trading

Extended hours trading encompasses any stock trading activity beyond the official hours of major stock exchanges, typically 9:30 AM to 4:00 PM Eastern Time (ET). This period is divided into pre-market trading (usually 4:00 AM to 9:30 AM ET) and after-market trading (typically 4:00 PM to 8:00 PM ET). Specific timeframes can vary slightly by brokerage firm.

Electronic Communication Networks (ECNs) make these non-traditional trading periods possible. ECNs are automated systems that directly match buy and sell orders from various market participants, bypassing traditional exchange floors and market makers. This direct matching allows for continuous trading, providing a platform for investors to respond to information as it emerges. The evolution of ECNs has democratized access to extended hours trading, which was once primarily available only to institutional investors.

Preparing for After-Hours Trading

To participate in extended hours trading, an individual must have an active brokerage account. Confirm your chosen brokerage firm offers extended hours trading capabilities, as not all platforms provide this service or the same extended windows. Many brokers also require clients to acknowledge specific risks associated with after-hours trading before enabling access. This ensures individuals are aware of the unique dynamics and potential challenges involved.

Extended hours trading typically only accepts limit orders. A limit order instructs the broker to buy or sell a security at a specified price or better, ensuring the trade will not execute at a less favorable price than intended. This contrasts with a market order, which executes immediately at the best available price but could result in an undesirable price during volatile extended hours. Limit orders help protect investors from unexpected price swings common outside regular trading hours.

Placing an Extended Hours Order

Placing an extended hours trade involves a specific process. First, log into your brokerage account and navigate to the trade entry screen, similar to placing a regular market order. Select the specific stock or exchange-traded fund (ETF) you wish to trade, indicate whether to buy or sell, and accurately enter the quantity of shares.

Next, select “Limit Order” as the order type, specifying a precise price at which the trade should execute or improve upon. Then, select the appropriate “Time-in-Force” option, which tells the broker how long the order should remain active and in which trading sessions. Common selections include “Extended Hours,” “Day + Extended,” or “Good Till Cancelled (GTC) Extended.” After all details are entered and the time-in-force is correctly set, review the order carefully before confirming and submitting it.

Important Considerations for Extended Hours Trading

Extended hours trading has lower liquidity. Fewer participants are active during these periods compared to regular market hours, which can make it more challenging to find a buyer or seller for a desired number of shares. This reduced liquidity can result in orders being only partially executed or not executed at all.

Lower liquidity directly contributes to higher volatility in extended hours trading. With fewer trades occurring, even a small number of orders can cause larger price swings than would be seen during regular market hours. This environment can lead to wider bid-ask spreads, meaning there is a greater difference between the highest price a buyer is willing to pay and the lowest price a seller is willing to accept. Wider spreads can result in trades executed at less favorable prices for the investor.

News announcements frequently impact extended hours trading. Many companies release earnings reports or other significant corporate news after the regular market closes or before it opens. These announcements can trigger rapid and substantial price movements during extended sessions. Even with a limit order, there is no guarantee of execution, as the price may move away from the specified limit before the order can be filled. Individual investors often compete with professional and institutional traders who have advanced tools and resources, potentially creating a disadvantage for less experienced participants.
