脚注 - 大于文本宽度

Question

我在使用 \footnote{...} 时遇到了一些问题。我已定义文档的边距和文本宽度。但是，每次我添加脚注时，它都会拉伸，直到文档的边距变得比实际文本宽度大得多。我尝试将边距更改为实际文本宽度，但无法做到。

谁能帮我？

下面是一个虚拟示例：

\section{Introduction}


Some random text here. A stock option is a contract between two people that gives the holder the right, but not the obligation, to buy or sell outstanding stocks at a specific price and at a specific date. Options are purchased when it is believed that the price of a stock will go up or down (depending on the option type). For example, if a stock currently trades at 40 and you believe the price will rise to 50 next month, you would buy a call option today so that next month you can buy the stock for 40, sell it for 50, and make a profit of 10. Stock options trade on a securities exchange, just like stocks.

A stock warrant is just like a stock option because it gives you the right to purchase a company's stock at a specific price and at a specific date. However, a stock warrant differs from an option in two key ways:

A stock warrant is issued by the company itself New shares are issued by the company for the transaction. Unlike a stock option, a stock warrant is issued directly by the company. When a stock option is exercised, the shares usually are received or given by one investor to another; when a stock warrant is exercised, the shares that fulfill the obligation are not received from another investor, but directly from the company. \footnote{footnote off margins}
