Anthony Elgindy was a man who did some very bad things. He used to buy and sell stocks in companies, which means he would try to make money by buying stocks for a low price and then selling them when the price went up. But instead of doing it in a fair and honest way, Anthony cheated and lied.
He called himself a "short seller," which means he would bet against the stock market. So if he thought a company's stock was going to go down, he would sell it right away, hoping to make money when the price dropped. He would also try to convince other people to sell their stocks too, so he could make even more money when the price went down.
But sometimes, Anthony would do more than just sell stocks – he would actually spread lies and rumors about the companies he was betting against. He would make up false information, like saying that the company was going to go bankrupt, or that they were doing something illegal. This would make other people nervous and sell their stocks too, making the price go even lower.
Anthony thought he was really smart and could get away with this, but eventually he got caught. He was arrested by the FBI and charged with many crimes, including extortion, fraud, and making threats. He was found guilty and went to jail for a long time.
So basically, Anthony Elgindy was a dishonest and greedy man who cheated and lied in order to make money in the stock market. But he got caught and went to jail, so hopefully other people will learn from his mistakes and do things the honest way instead of trying to cheat and steal.
