Tracking Correlations: Risk, Trailing correlations, correlation coefficients and Trading decisions
Agnes recently did a lot of work in putting together a short course on correlations from a risk and trading point of view. Unlike the boring text book stuff, there are some interesting lessons and applications here if you want to track correlations over a period of time as a trader or risk manager. This is the same methodology we use to track crude oil, precious metals (gold, silver) and currencies as part of our own internal analysis. Given the number of queries we get on our methodology I thought this post should put a lot of questions to rest.
Enjoy the course.
Next raw data time series line graphs such as price trends and derived data graphs such as volatility trend lines including the methodology for constructing line graphs in EXCEL.
Scatter plots, a visual representation of the correlation coefficient tackled a little bit later on the course.
The trailing correlations graph, a graphical representation of how correlations have changed over a period of time.
Finally, we look at an additional way of viewing the time series data of two factors- the relative price graph and its various uses:
