New research from Scientific Beta has suggested institutional investors leverage ‘completion portfolios’ to mitigate any gaps in their portfolio exposures due to changing market conditions.

The index solutions provider said completion portfolios can be used to “address unintended misalignments that can develop between their desired market positioning and actual portfolio composition” by realigning overall exposures with the strategic investment goals put in place.

The research paper, The Power of Completion: How Completion Portfolios Enhance Alignment, Efficiency, and Flexibility, written by Index Director and Deputy CEO Daniel Aguet, the group’s Head of Investment Solutions for Australia and New Zealand, Warwick Schneller, and Senior Quantitative Analyst, Saba Sinaee, found certain gaps have emerged as US growth stocks – such as the highly popular ‘Magnificent Seven’ – have consistently outperformed value stocks.

This has seen several market cap-weighted portfolios develop “unintended growth tilts”, alongside “regional imbalances” caused by the rise of multi-manager global equity portfolios.

“The fundamental value of completion portfolios lies in their ability to bridge the gap between strategic intent and actual portfolio composition,” the research said.

“Completion is not a replacement mechanism—it’s a precision tool.

“Completion portfolios represent a solution to the persistent challenge of portfolio management: ensuring that investment allocations consistently reflect an investor’s core objective.”
