Based on what you've learned about the stock market crash of 1929, which of the following might help you spot another stock market crisis? Check all of the boxes that apply.

Widespread buying on margin is risky because investors borrow money to buy stocks and may be forced to sell if prices fall. A one-day drop of 20% is also a strong warning sign; a small rise in prices over a few days, by itself, does not indicate a crisis.
