How many stories is the one world trade center have. Very large datasets – comprising voluminous numbers of symbols – present challenges for the analyst, not least of which is the difficulty of visualizing relationships between the individual component assets.Absent the visual clues that are often highlighted by graphical images, it is easy for the analyst to overlook important changes in relationships.One means of tackling the problem is with the use of graph theory.In this example I have selected a universe of the Dow 30 stocks, together with a sample of commodities and bonds and compiled a database of daily returns over the period from Jan 2012 to Dec 2013.

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. We will use the graph theory to show how the relationship between the components has changed through years.Network Theory in Finance Applications to Financial Contagion Analysis and Portfolio Optimization DOCTORAL THESIS. of the precision matrix as a network opens the possibility to implement investment strategies based on network indicators.
