Investment model (portfolio model)
If not defined otherwise, this term refers to purely logically based advice to an investor on how to set up his portfolio in the most favorable way. The instructions, which are usually highly mathematized (mathematically-modeled), generally neglect the crucial tax saving aspects that are extremely important in the decision-making process and are often the only decisive factors. Therefore, such models are of limited help to investors in their decision making. – See investment risk, behavioral finance, expectation theory, new, financial engineering, financial mathematics, financial psychology, financial theory, formulas, financial mathematical, portfolio optimization.
