I am still definitely in the proof of concept stage, but as I progress I get more excited about the prospects of combining d3.js with R and Axys through Bryan Lewis’ really nice R websockets package (even nicer now that he has added the daemonize fun...

When I saw the answer to this Stack Overflow question, I immediately remembered working on my old post Clustering with Currencies and Fidelity Funds and just had to try to apply this technique.  As I should have guessed, it worked with only a mini...

US investors were spoiled by US Treasuries which acted as a near perfect hedge to stocks during the 2008-2009 crisis.  However, in real crisis, bonds rarely offer any comfort, and asset allocation fails (see post Death Spiral of a Country and IMF ...

In Crazy RUT, I started to explore why the moving average strategy has failed for the last 2 decades on the Russell 2000.  I still do not have an answer, but I thought looking at skewness and kurtosis might help explain some of the challenge of be...

Like many, I have been in awe of the d3.js and cubism.js visualization packages created by Mike Bostock. Mike Bostock @ Square talks about Time Series Visualization from Librato on Vimeo. The charts are beautiful and extraordinarily functional, so I th...
