It’s easy to watch financial shows on television and feel like a fool for missing opportunities to pick up “screaming buys,” in “beaten-down markets,” but at a time when home values are in the gutter and people are worried about where their next paycheck is coming from, it’s more important than ever to understand what’s involved before you play the Wall Street game. In our nest report Nicole takes us on a tour of the New York Stock Exchange. The NYSE was founded in 1792 and today billions of dollars exchange hands there everyday. More than 2,000 companies trade their stock there. Owning stock is like owning a stake in a company, if the company does well you can make money, if it does badly you can lose money.
