MOTAD and Target MOTAD procedures are alternatives to mean-variance quadratic programming analysis and employ linear programming procedures to derive efficient portfolios. Target MOTAD hasseveral advantages over MOTAD. A very important one is that allows for estimation not only at the average but also at the tails of the distribution, where the worst conditions occur. In Target MOTAD theexpected returns below the target equal the negative deviations from MOTAD analyze (Table1).

TargetMOTAD

Conclusions are: i) as risk increases, mean annual growth increases, as well; ii) Target MOTAD generates higher values for the same growth rates. Thus, minimizing only the negativedeviations leads to more efficient portfolios. The model incorporates a safety level of growth and also allows negative deviations from that safety level. Target MOTAD measures risk from a difference point...
