Rally in the Stock Market

What is a Rally in the Stock Market?
A rally can be described as a sudden rise in stock prices, especially after a period of falling ones. [For example, if the stock market drops in the morning and investors rush in to buy companies at the cheaper prices, the stock market has rallied.]
If the increase in stock prices holds up, journalists and financial professionals refer to it as a sustained rally. If it continues for several weeks or months, it is referred to as a bull market.
