The statement that if some security were not part of the efficient portfolio, then every investor would want to own it and demand for this security would increase causing its expected return to fall until it is no longer an attractive investment is false. If a security is not part of the efficient portfolio, it means that it is either inefficient or redundant, and no rational investor would want to hold it. Therefore, its expected return would not fall due to increased demand.
