The Fama and French (1992 and 1993 etc.) factor ranking approach is very popular among quantitative fund managers. However, this approach suffers from hidden factor view, loss of information, etc. issues. Based on the Black-Litterman model (Black and Litterman, 1992; as explained in Cheung, 2009A), we design a technique that endogenises the ranking process and elegantly resolves these issues. This model explicitly seeks forward-looking factor views and smoothly blends them to deliver robust allocation to securities. Our numerical experiments show this is an intuitive and practical framework for factor-based portfolio construction, and beyond.

The paper is featured by:
- A new and unified framework for strategy combination, factor mimicking and security-specific bets
- An elegant and ranking-free approach to factor style construction
- Worked examples based on the FTSE EUROTOP 100 universe
- Insight into the classic issue of confidence parameter setting
- An implementation guidance in the appendix
