This article explores the advantages of 130/30 funds over traditional long-only products. It starts with the basics of how a 130/30 portfolio is constructed. While simple in theory, there are many more moving parts for 130/30 products that both builders and investors must consider. Second, the article uses the Fundamental Law of Active Management to demonstrate mathematically why 130/30 products can be superior to traditional long-only products. It then applies the Calculus of Active Management and demonstrates in a series of graphical presentations how 130/30 products can outperform traditionally managed portfolios. Last, as a reminder of some of the problems with traditional active portfolios, is a snapshot of an existing long-only product and a clear insight into why these products often produce inferior results.}, URL = {https://guides.pm-research.com/content/2008/1/16}, eprint = {https://guides.pm-research.com/content/2008/1/16.full.pdf}, journal = {Special Issues} }
