Mr. Anton Liliwaton is considering building a portfolio containing two assets: Asset Sy and asset Nah. Asset Sy will represent 60% of the peso value of the portfolio and asset Nah will account 40%. The expected returns over the next 5 years, 2021 to 2025 for each of these assets are as follows:

	Expected returns
Year	Asset Sy	Asset Nah
2021	19%	12%
2022	17%	14%
2023	16%	16%
2024	15%	18%
