Related to support level: Resistance level
In technical analysis, a price that a security does not or only rarely falls below. Technical analysts identify a support level by looking at past performance. It is seen as an indication to buy the security, which will increase the demand, causing the security's price to move above the support level. The demand comes from investors who fail to buy the security at the support price, and resolve to do so if it reaches that price again. If buyers are not forthcoming, however, the security falls below the support level. When this occurs, the price of the security will likely continue to drop until it finds another support level. See also: Price floor, Resistance (Resistance level).
A price at which a security or the market will receive considerable buying pressure. Technical analysts believe demand at the support level will tend to keep a stock's price from falling below the support-level price. A support level develops as investors miss purchasing a stock just before a price rise and resolve to buy the stock if it again reaches that level. Compare resistance level.
