What were the two trading terms that Flora Baumbach had learned, and what do they mean?

In The Westing Game, Flora Baumbach learns two trading terms used in relation to the stock market. The first of these is "bullish." This refers to a situation when investors are in a confident mood. They tend to buy more stock, and so a bull market is one where the overall price of stocks increases. Flora notices this herself when the stock market rises three points in the morning.
The other trading term Flora learns is "bearish." A bear market is one where investors tend to be quite pessimistic. For one reason or another, they start selling their stocks and the price falls accordingly. Flora notices that having risen three points in the morning, the stock market falls five points in the afternoon.
