Filter

A rule that stipulates when a security should be bought or sold according to its price action.

Filter Rule

In technical analysis, an arbitrarily set percentage of increase or decline in a stock's price that the analyst sees as an indicator to buy or sell the stock. For example, the analyst may set his/her own filter rule at 15%. If the stock rises 15%, the analyst recommends buying; if it falls 15%, he/she recommends selling. While the particular percentage is subjective, one arrives at it by observing the stock's historical trends. The filter rule exists to help the investor avoid buying or selling at insignificant or anomalous changes in price. However, many analysts do not believe that the filter rule consistently produces profits for the investor.

Figure 4 shows changes in the subtracted intensity of the infrared band at 1728 [cm.sup.-1] for amine-cured epoxy specimens exposed under a bandpass filter with center wavelength 326 nm and neutral density filters. The superposition of all intensity levels on the same master curve when plotted as a function of dosage is once again indicative that reciprocity is obeyed.
