Do Active Asset Managers
Create Value?
January 2016
Key Findings
‘Unrefined’ amLeague rankings show a clear ability from active asset-managers to add
value compared to benchmark’s performance.
However, this added value may be questioned because of several biases. In the following
study, amLeague addresses in depth these biases.
The ‘average’ active portfolio manager brings a yearly outperformance. Yet, this
outperformance depends on the market trend: it is enhanced in case of bear markets; it
is weakened but not annihilated in case of bull markets.
In (unfavourable) case of stagnant equity markets, this added value amounts to
1.6% per year (Europe equity mandate). This magnitude has been confirmed
through different simulations, proving by the way that the survivor bias can be efficiently
prevented.
This 1.6% annual outperformance derives from a ‘all Asset Managers included’ approach.
Much more attractive figures are achievable when adding ‘selection value’ to ‘basic asset-
managers value’.
With a purely quantitative selection methodology, it is possible to build an active asset-
management index, amLeague_Europe 75©
, fully adapted to professional replication:
75 lines only, quarterly reshuffling, 5 days notice before implementation.
Since July 5, 2012, amLeague_Europe 75 provided a 4.8% annualized spread vs
passive STOXX®
Europe 600 benchmark, with a 100% one year outperformances’
frequency and a 100% 2 year outperformances’ frequency.
Yes, active asset-managers do create value; and this value can be significantly
enhanced and operationally replicated
