Stock MArket
The rapid growth of the stock market was partially because of an increase of people investing in the stock market. When people buy on margin they are basically putting down a really small down payment on stocks. When stock prices continue to rise for a long time it is called bull market. That makes bear market the opposite where prices for stock keep going down for a long period of time. When the stock market is booming it is improving and when it's in a recession it's deteriorating. Many investors speculated that the market would continue to increase, but when the market began running out of new customers, prices began to plummet. When investors speculated that the market was in trouble they began selling their holdings. The crash of the stock market was due to lower investment and prices.
