A lot of people might not know this but insider trading is illegal at least in the US, well the United States has the largest stock markets in the world, the new York Wall Street markets is estimated to trade billions of dollars in stocks. Insider trading means the trading of a public or private companies stock based on material information provided by the employee of the company or know associate of the company. With the US market so global, what are your thoughts about insider trading, do you think these companies do insider trading??. In my honest opinion I think a huge part of them trade based on insider information.
