Bull

A particular kind of investor who purchases shares in the expectation that the market price of that company's share will increase.

S/he sells her/his stock at a higher price and pockets the profit. Simply put, the bulls buy at a lower price and sell at a higher price.

For instance, if a bull buys a company's share at Rs 100, s/he would prefer selling the same stock at Rs 120 or any price higher than Rs 100 to make a profit.

Usually, a bull buys first at a lower price and sells later at a price higher than her/his cost of purchase.

Bulls are happy when the markets (the Sensex and Nifty) move upwards. A falling market takes bulls into hibernation.
