Minimum Spanning Trees and Planar Maximally Filtered Graphs are generated from correlations between $300$ most capitalized $NYSE$ stocks' daily returns, computed dynamically over moving windows of sizes between $1$ and $12$ months, in the period from $2001$ to $2003$. We study how different economic sectors differently populate the various regions of these graphs. We find that the financial sec...
