Bear

Bull's counterpart is the bear.

A bear sells stocks first that s/he owns or borrows from, say a friend, and then purchases the same quantity of shares at a lower price.

If a bear sells first, say 100 shares of Ranbaxy at Rs 400, and later purchases the same number of shares at Rs 375, then her/his profit is Rs 25 (400-375) per share.

This way s/he has got back the 100 shares of Ranbaxy and simultaneously made a profit of Rs 2500. The shares can later be returned to the bear's friend if s/he had borrowed the same from a friend.

There are bears in the market that sell shares first without actually owning them unlike in the above example. Such selling is called naked short selling or going short on a stock.

Bears are happy in a falling market.

While individual investors can engage in selling first and buying later (also referred to as short selling), mutual funds and foreign institutional investors are not allowed this luxury in India yet.
