1. A method for classifying assets into business sectors, said method comprising:
- (a) utilizing a computer to execute computer-executable process steps that include steps to;
(i) calculate, for each of plural exogenous variables, a measure of a tendency for a value of an asset to change as a result of a change in a data value for said each exogenous variable;
(ii) repeat step (i) for each of plural different assets; and
(iii) group said plural different assets into plural different sectors based on similarities of said measures of tendency to change across said plural exogenous variables;
(b) assessing at least one of;
(I) how statistics for at least one of the groups formed in step (iii) vary over time; and
(II) how one asset in a group formed in step (iii) compares to other assets in the same group; and
(c) purchasing or selling an asset based on the assessment made in step (b).

Abstract
Provided is a technique for classifying stocks into business sectors by calculating, for each of multiple exogenous variables, a measure of a tendency for a value of a stock to change as a result of a change in a data value for each such exogenous variable. The foregoing step is then repeated for each of several different stocks. Finally, the different stocks are grouped into different sectors based on similarities of such measures of tendency to change.
