Killing transactions refer to transactions in stocks, futures and other trading markets that are so large that they cause large price fluctuations or continuous declines. This kind of transaction is usually carried out by large investors, fund managers or important market institutions with the purpose of obtaining huge profits or overwhelming market position. Once the kill order is implemented, it will cause significant fluctuations in the entire market and will also have a great impact on other investors. Therefore, it is sometimes regarded as irresponsible trading behavior.

Although selling may bring huge profits, it also involves great risks. Because once the market reacts quickly and prices fall excessively, investors may face risks and suffer heavy losses. At the same time, killing orders can easily cause market chaos or investor panic. Although large institutions will consider selling as a strategic decision, after all, it does not always succeed in entering the market.

The concept of selling is usually only used in trading markets such as stocks and futures. However, some people have extended it to other fields, such as media. In the media field, there are sometimes hype articles and investor behaviors such as publishing false information. At this time, once it is subject to what we call "killing", the company's stock may fall sharply in a short period of time. Therefore, no matter which field they are in, investors should understand the impact and risks of selling and make responsible decisions.
