Portfolio (finance) compresses multiple socialscienceshumanitiesarts details into a stable diagnostic relation. The source shows both the central mechanism—this is an example of a multi-objective optimization problem: many efficient solutions are available and the preferred solution must be selected by considering a tradeoff between risk and return.—and the practical consequence—it is a generally accepted principle that a portfolio is designed according to the investor's risk tolerance, time frame.
Abstract Reasoning¶
- Type the carrier. Identify the socialscienceshumanitiesarts entities to which the claim applies.
- State the relation. Use the source-grounded identity: In finance, a portfolio is a collection of investments.
- Check operation and conditions. In particular, a portfolio A is dominated by another portfolio A' if A' has a greater expected gain and a lesser risk than A.
- Demand recognition evidence. One traditional method is using quarterly or monthly money-weighted returns; however, the true time-weighted method is a method preferred by many investors in financial markets.
