A market is said to be bullish if there is a rise in the prices of securities. This means that the investors are optimistic about the market conditions and are buying stocks and other securities, which leads to an increase in their prices. A bullish market is generally seen as a sign of a strong and healthy economy, as investors are confident about the future prospects of the companies whose stocks they are buying. When the market is bullish, people are more likely to invest and take risks, as they believe that the prices of securities will continue to rise, resulting in profits for them.
