To talk about some special topics, we need learn some special words.
Take stocks as an example. I don't think many of us have stocks of US and Canadian companies, because we have been here not for a long time. If you are learning English as I do, you may browse some financial news on the Internet or in the newspaper. You will frequently see a word---scoop. By scoop people mean some information from the inside, or inside information. If you have some scoop, you can take a lot of advantages in buying and selling the stocks. Every year, some big figures in the USA are put behind the bar because they utilized the scoop.
