I am looking for references that are specific to quantitative trading strategies that exploit low-frequency dislocations in markets, which lend themselves as overlays for a strategic asset allocation of a multi-asset portfolio (equities, high-yield credit, bonds, precious metals) that improve the overall portfolio performance statistics. Instruments used could be quite flexible, for example futures, options or CDS.
One reference that I already found is Advanced Futures Trading Strategies by Robert Carver, but only a few strategies covered would come close to the description above.
