Final answer:
All of the options mentioned can be present in a well-diversified portfolio.
Step-by-step explanation:
In a well-diversified portfolio, all of the options mentioned can be present.
A well-diversified portfolio typically includes a mix of different asset classes such as stocks, bonds, and precious metals like gold or silver.
The purpose of diversification is to spread out the risk across different investments, so if one asset class underperforms, the others may provide stability or even growth.
For example, during times of economic uncertainty, gold or silver may act as a hedge against market volatility.
