Causes of a bear market
The usual cause of a bear market is investor fear or uncertainty, but there are a multitude of possible causes. While the global COVID-19 pandemic caused the 2020 bear market, other historical causes have included widespread investor speculation, irresponsible lending, oil price movements, over-leveraged investing, and more.
Bear vs. bull
A bull market is essentially the opposite of a bear market. Bull markets occur when there is a sustained rise in stock prices, and they are typically accompanied by elevated consumer confidence, low unemployment, and strong economic growth.
