The correct answer to this open question is the following.
A bull market is when there's a rise or expected rise in stock prices across the entire stock market.
In financial and banking terms, a bull market means the time when prices rise permanently. It could be months or even years. This is that securities in the stock market are rising or are predicted to do so. This phenomenon can better be seen when the economy of the country is strong when companies have good profits and unemployment rates are low.
