This page contains two analytical tools: one for correlations and one for factors.

The correlation tool will help you find the most and least correlated ETFs with the your specified security. Use it for trade idea generation and to identify effective substitutes and complements for your portfolio holdings.

The factor tool runs a multiple regression on a selected list of ETFs ("factors") and helps you identify the driving forces behind the specified security. The coefficients represent the sensitivity to each of the factors, whilst R-squared shows how successful the overall model is. The regression is unrestricted, thus the coefficients can take any positive or negative values.

Simply input a ticker recognized by Yahoo! Finance and choose a group of ETFs to be used for analysis. We have included in the lists only ETFs with at least $1 billion in assets and 5 years of trading history. The lists are updated on a quarterly basis.
