If we want to look at how the assets are correlated, one way is to created an adjacency graph that maps the interrelations between assets that are correlated at some specified level (0.5 of higher, in this illustration).Obviously the choice of correlation threshold is somewhat arbitrary, and it is easy to evaluate the results dynamically, across a wide range of different threshold parameters, say in the range from 0.3 to 0.75: The choice of parameter (and time frame) may be dependent on the purpose of the analysis: to construct a portfolio we might select a lower threshold value; but if the purpose is to identify pairs for possible statistical arbitrage strategies, one will typically be looking for much higher levels of correlation.Reverting to the original graph, there is a core group of highly inter-correlated stocks that we can easily identify more clearly using the Mathematica function Find Clique to specify graph nodes that have multiple connections: We might, for example, explore the relative performance of members of this sub-group over time and perhaps investigate the question as to whether relative out-performance or under-performance is likely to persist, or, given the correlation characteristics of this group, reverse over time to give a mean-reversion effect. More data in a graph. When you have few data, the graph theory is not useful, or at least, you do not take advantage of all its power. Now we take the S&P500 index and its components.
