Cluster analysis,

Definition of Cluster analysis:

1. Cluster analysis is a technique used to group sets of objects that share similar characteristics. It is common in statistics.

Stocks that exhibit high correlations in returns fall into one basket, those slightly less correlated in another, and so on, until each stock is placed into a category.

Diversification remains one of the central tenants of investing and cluster analysis is just one channel to achieving it. .

Statistical classification technique in which cases, data, or objects (events, people, things, etc.) are sub-divided into groups (clusters) such that the items in a cluster are very similar (but not identical) to one another and very different from the items in other clusters.
