Traditional factor models suffer from structural decay
The guest argued that traditional quantitative factors like cheapness to the market have decayed, requiring managers to construct customized, non-traditional peer groups to identify true valuation anomalies.
The argument
Historically, value managers relied on static rubrics like price-to-earnings or price-to-book relative to the broad market. The guest argued that because businesses change and some structurally trade at premiums, grouping companies by symbiotic relationships (e.g., Union Pacific and Prologis) or actual business models (e.g., Sherwin Williams with home improvement rather than commodity chemicals) is necessary to find mean-reverting distributions.
The thesis, stress-tested
✓ What validates it
- ✓Outperformance of customized peer-group portfolios relative to traditional GICS-based value benchmarks
▸ Risks discussed
- ▸Custom peer groups rely on subjective classifications of 'symbiotic' relationships
- ▸Historical factor decay may not be fully solved by new grouping methods
Hear it yourself
"I think, well, the way that I try to tackle this challenge with factor decay, because I still believed in wanting to focus on low valuation or a whole client base. That's what we've done, and we also had an income focus."
