The assignment content discusses the concept of market efficiency and how it affects investment decisions in an asset management company. In an efficient market, investors can earn better returns by investing in companies that perform better than others. The strategy used is simple trading and evaluating positive and negative information about a company. However, diversification is also important to hedge against risk. An asset management company takes money from clients and invests it in different investment options such as mutual funds, pension plans, and hedge funds. Diversification is the main investment philosophy of these companies, which allows them to earn higher returns and hedge against market risks.
