The stock market is a weird one to me. One day something can be up high in price, and the next it falls. What happens if something in the stock market just drops down to next to nothing in worth? What happens in those cases? Does the stock ever rebound? I don't know a whole lot on stocks, but I imagine if a stock rises to a big amount, and then drops, it's not good for that company right? Has a stock ever just blown up because of this?
