A bear market refers to a financial market in which prices are falling or are expected to fall. The term is typically used to describe a stock market, but it can also refer to other markets such as the bond market or the real estate market.
A bear market is characterized by decreased investor confidence and pessimism, as well as a high level of selling activity. This results in falling prices for securities, such as stocks and bonds, and decreased trading volume. The opposite is a bull market, which is characterized by rising prices and a high level of investor confidence.

Bear markets can last for varying lengths of time, and they are often driven by factors such as economic recession, high unemployment, and high inflation. However, it can also be triggered by external events such as natural disasters or geopolitical crises.
During a bear market, it's generally a good time for investors to focus on preserving capital rather than generating returns. It is also important to note that they are not always negative and it can be an opportunity for investors to buy stocks at a lower price.
It's important for investors to have a long-term perspective and not to make decisions based on short-term market fluctuations. A diversified portfolio and a solid investment strategy can help investors weather a bear market and take advantage of opportunities that may arise during these challenging times.
