Leek cutting is a kind of market behavior, which means that some people or institutions use their information advantages, skills and experience to gain benefits from ignorant or self-righteous small investors in a malicious way, so that the interests of small investors are repeatedly damaged and the victims are unable to defend their rights, just like cutting leeks one by one and constantly exploiting them.

Specifically, the act of cutting leeks may use some means or skills, such as manipulating the market manually, using funds to allocate a large number of stocks to form a so-called "banker's market" to create short-term gains, and then selling them when the stock price reaches a high level, thus making a profit. At the same time, leek cutting may also appear in other financial products, such as some internet financial products, virtual currency games and so on.

Cutting leek is very unfavorable to small investors, because it will seriously affect the fair and transparent order of the market, lead to high fluctuation and instability of the stock market, and increase the risks and losses of small investors. Therefore, the regulatory authorities should strengthen the supervision and crackdown on leek cutting, maintain the fairness and transparency of the market, and protect the rights and interests of small and medium investors. In addition, small investors should protect themselves, be wary of short-term speculation and high-risk investment, improve basic financial knowledge and risk awareness, and choose standardized, legal and transparent investment channels to avoid becoming victims of leek cutting.
