All over after hours trading
Online brokers have made entering the stock market a lot easier. Investing is no longer something for old rich men with privileges. In fact, investing is becoming more accessible every day and new opportunities are constantly emerging. After hours trading is one such possibility. You then have access to the stock exchange, while it is actually closed. This may raise a lot of questions, because how does this work exactly? You can read all about it in the article below.
After hours trading: what is it?
As the English term ‘after hours trading’ suggests, it is the possibility to trade in shares outside the current opening hours of the stock exchange . What those opening hours are exactly depends on the stock exchange you are talking about. For example, the Dutch stock exchange ( Euronext Amsterdam ) is open from 9:00 to 17:30 on trading days. Exceptions may occur on public holidays.
When you start trading after the stock market has officially closed, you will probably notice that the price in the graph is no longer moving live. However, you can see at what speed trading is taking place, which means that the prices of shares can still move along. You simply indicate for what amount you want to buy shares. If the specific shares are sold at that price by someone else, your order will be executed.
Since there are fewer trading movements after the market closes, it is conceivable that the amount you set will not be matched. This happens when no one sells their shares for that specific amount. As a result, your order will be destroyed when the market opens again according to regular trading hours.
Only for professional investors?
After-hours trading has been possible for decades. Initially, these possibilities were only available to professional parties that made large-scale investments. However, the arrival of online brokers has caused a change. After the first online brokers came into existence, after-hours trading was no longer reserved for professional traders; private individuals were also given the opportunity to trade outside of stock exchange hours.
Not all brokers automatically offer after-hours trading options. If you find this an important functionality, you will have to specifically select your broker. Many brokers work with a derivative variant, where it is possible to trade before and after the market during extended opening hours.
What is the use of after hours trading?
Although it may seem somewhat absurd at first glance to trade outside the opening hours of the stock exchange, after hours trading has one very big advantage. This has everything to do with the fact that investors act, among other things, on the basis of the information available at the time. If the circumstances regarding a certain share change, you can choose to buy or sell it immediately. However, there is a limit to this: the opening hours of the stock exchange. This limit is removed by the possibility of after hours trading.
A practical example is the situation in which a company presents quarterly figures. These figures conceal a great deal about the financial situation of the company in question. As an investor, you want to be able to act quickly when the quarterly figures give reason to do so. These figures are usually presented before or after the market closes, which is why after-hours trading can offer a solution.
In addition to quarterly figures, there are many other situations that require quick action. For example, developments within the company itself or steps taken by the competition. Political, social and societal factors can also create the desire for after-hours trading options. After all, global developments do not stop when the stock exchange closes.

The pros and cons
The ability to trade before or after hours can be nice. However, there are also disadvantages. Below you will find the most relevant advantages and disadvantages associated with after hours trading.
Advantages
- Anticipating new information. If there are relevant developments before or after the market opens, most investors will only respond to them when the market opens. With after-hours trading, you get the opportunity to be one of the first to take a position. In this way, you respond to new information before the crowd does.
- Ease of use and peace of mind. The possibility of after-hours trading offers additional ease of use. On the contrary, it can cause inconvenience if you actually want to open a position outside the opening hours of the stock exchange. In addition, it gives peace of mind that you are always able to trade if something happens. This way you keep control over your portfolio.
- Cheaper. In some cases you can trade ‘cheaper’ outside the opening hours of the stock exchange. This is the case when the price opens higher than it closed the previous day and you have opened a position between these times.
Disadvantages
- Low liquidity and slow order execution. Most traders stop trading when the market closes. There are plenty of traders who trade after hours, but not enough to ensure high liquidity . Every time you want to buy stocks, someone has to sell them at the price you want. Sometimes it takes a long time to find someone, which means your order will not be executed quickly – or not at all.
- Volatility. Precisely because there are so few investors active after hours, the price can show quite large movements. This can bring with it a certain degree of unpredictability that you as a private investor can do little with.
- Backlog in expertise. Although it can be nice to be able to trade after hours, you should realize that you are then playing with the larger investors. These are often professional traders who trade before or after the market. These traders often have more knowledge, money and experience. This can be a disadvantage if you are not a professional trader.
Tips for after hours trading
If you are used to trading during stock market opening hours, it may take some time to get used to trading before or after market hours. In order to prevent excessive losses as much as possible, it is therefore wise to read up on the subject. Below you will find a number of tips that can help you when investing outside stock market opening hours.
1. Follow the developments
It is no secret that many investors speculate on stock prices by (trying to) recognize trends. Before you start trading outside opening hours, it is wise to keep an eye on the stock in question for a while. If you know that a certain stock almost never opens in the plus, then it may be less obvious to take a position before or after market hours. In addition, it is always relevant to keep an eye on developments in the news.
2. Know the opening hours
After hours trading: fun, but what are the ‘hours’? If you plan to trade outside the opening hours of the stock exchange, you will first need to know what these opening hours are exactly. Converted to Dutch time, the NASDAQ is open from 15:30 to 22:00. The Euronext Amsterdam is open from 09:00 to 17:30. Take weekends and holidays into account. For each stock exchange you can find on which (special) days it is and is not open.
3. Think about the spread
Because there are fewer traders active when the stock exchange is closed, liquidity will be relatively low after the stock exchange closes. There are then few investors who sell shares. In practice, this often leads to a high spread . This is the difference between the bid and ask price. If the difference is too high, this can lead to increased risks.
Conclusion
After hours trading is a special concept offered by many modern brokers. It gives you the opportunity to trade in shares even after the stock market closes. This gives you a certain degree of flexibility and gives you the chance to beat the crowd, so to speak. However, pre- and after-hours trading is largely the territory of professional traders who can easily beat you to it. Due to the low liquidity, after hours trading is a ‘different matter’ than trading during regular stock market hours. This is why it is wise to read up on it first.
