In light of recent events... So when the news says that the DOW is up 400 so-and-so points, what exactly does it mean? What are "points" and what is it "up" in relation to, the beginning of the day? Stocks seem very interesting to my and a working knowledge of them may come in handy to me if I ever wish to invest, does anyone recommend a resource I can use to learn everything I need to know? Danke.
