Quantitative financial analysis successfully applied to portfolio management.

Can historical data on securities be used to determine if any given rule-based plan for active investment management is well-drawn or not, so that existing programs can be improved and new and better ones developed?

    The charts of this page show outcomes of a new form of active asset management that has been pioneered by Mike O'Connor. It is highly effective at reducing market risk— without reducing returns. The strategy and the evidence that it works are presented in detail in the working paper Repurposed “Shrinkage Estimator” Deftly Allocates to Risky Assets, which is downloadable below. It explains the strategy in plain language and it also fully discloses the details of the algorithm.
