Investor sentiment is the view of the market by investors. This is the combined view of all investors at any one time. Since this is not static, but rather always changing, investor sentiment is usually seen in three general categories: extremely optimistic (bullish); extremely pessimistic (bearish); and neutral or equal in number of optimists and pessimists. The view of investor participants can be based on either fundamental or technical reasons. Investor sentiment is seen as moving the main indices, which will push individual stocks in its wake. For example, a company might not be a great stock, but if the investor sentiment for the overall index is extremely bullish, this optimism will push up the price of most, if not all, stocks. Many view extreme market sentiment readings as a contrary indicator; when most people are bullish (optimistic), the market is close to a short-term top and vice versa.
