Definitions needed
As the article stands, it uses so many undefined terms that it is incomprehensible. For example,
- financial network Is this a computer network? A "buddy" network of inside traders? Something else?
- the last decade Wikipedia articles should not be written to be ephemeral.
- distance between the stocks undefined
- Methods Methods for doing what? Without knowing this, it is impossible to make sense of the section.
- correlation between each pair of stock[s] undefined
- time series Maybe price history. In any case, it needs to be stated.
