The cardinality-constrained mean–variance portfolio optimization model with and without short selling and risk-neutral interest rate is studied and an improved model is presented, where instead of determining the term of the short rebate according to the proportion of the total funds invested, it is determinedaccording to the return.

An improved variant using absolute returns instead of the returns to include short selling in the model is presented and some numerical results are provided using the data set of the S&P 500 index, Information Technology, and the MIBTEL index in terms of returns and Sharpe ratios.

This study incorporates the short-rebate gain in the minimum variance model by analyzing several constraints that aptly consider the different practical settings of a short sale transaction by imposing bounds on 1- and 2-norm that respectively generate sparse and diversified portfolios.

It is argued that simplifications of portfolio selection may no longer be necessary, based on computational advancements of portfolio theory and powerful computers, and some speedy results support removing the simplification.

It is shown that under certain conditions, the classic graphical technique for deriving the efficient portfolio frontier is incorrect and the most important implication derived from these characteristics, the separation theorem, is stated and proved in the context of a mutual fund theorem.
