is a procedure of allocating resources, generally money, in order to get some benefit in the future.
In finance, the benefit from an investment is called a return. The return may consist of a gain (or loss) realised from the sale of a property or an investment, unrealised capital appreciation (or depreciation), or investment income such as dividends, interest, rental income etc., or a combination of capital gain and income. The return may also include currency gains or losses due to changes in the foreign currency exchange rates.
Investors generally expect higher returns from riskier their investments. When a low risk investment is made, the return is also generally low. Similarly, high risk comes with high returns.
Investors, particularly novices, are often advised to adopt a particular investment strategy and diversify their portfolio. Diversification has the statistical effect of reducing overall risk.
Types of Investments
Investors famous for their success include Warren Buffett. In the March 2013 edition of Forbes magazine, Warren Buffett ranked number 2 in their Forbes 400 list. Buffett has advised in numerous articles and interviews that a good investment strategy is long-term and due diligence is the key to investing in the right assets. Edward O. Thorp was a highly successful hedge fund manager in the 1970s and 1980s who spoke of a similar approach. The investment principles of both of these investors have points in common with the Kelly criterion for money management. Numerous interactive calculators which use the Kelly criterion can be found online.
