Measuring Risk in a Portfolio
Importance of Diversification
Diversification is a critical risk management tool in portfolio management. However, over-diversification can be counterproductive. When a portfolio contains too many securities, it may be challenging to achieve superior performance. Moreover, the accounting, research, and valuation functions may become unnecessarily complicated.
Limiting Losses: Strategic Approaches
Portfolio managers employ various strategies to limit losses on individual securities or a portfolio as a whole, most involving the use of derivatives. Here are some common strategies:
- Put Options: These are used on individual equities or investments such as gold, silver, and currencies.
- Portfolio Hedging: This involves using derivatives on stock indexes, bonds, or interest rates to hedge an entire portfolio.
Applications of Derivatives
Put Options
Put options give the holder the right, but not the obligation, to sell a specified amount of an underlying asset at a set price within a specified period. They are often used to hedge against potential declines in the price of the underlying assets.
