The best way to do this is to create your own Managed SIMs and then
add those to a portfolio of SIMs. Why would you simply place the alpha
in the SIM when it means you will assume the manager will out perform
the chosen index each and every year?
The alpha input is there for those planners looking to show the
effects of a positive alpha and a negative alpha. Since Active
Managers do not outperform their benchmarks consistently over long
periods, return the the mean would dictate that a manager will
underperform in the future.
this being said, if you are going to show positive alpha for active
managers, you should always show negative alphas. Run 2 different
Retirement Plan Audits.
