做之前，先明白风险是什么：
Risk is commonly thought of as the probability of a loss. In investment terms, it is the probability that you might part or all of your investment. Generally speaking, investment with lower risk have a higher probability of getting positive return and vice verse, investment with higher risk have a lower probability of getting positive return. For example, a government bond is very low risk. At the start, you can calculate how much income you will receive during the investment period and how much capital you’ll receive back at the end of the investment period.
In comparison, a share investment can be moderate higher risk in the short term. For example, purchase shares in CSR. You can estimate the amount of dividend you may receive through past history, but each dividend will depends on the company’s strategy at the time. Capital growth of CSR are also much more unpredictable as changes in economic, government decision, company profitability, competition environment, business cycle and even season can effect the company’s share price.
However, risk is dependant on time frame and risk generally decreases with time. So a long term investment (say 10 years or more) could have a high likelihood of giving you the average return you expect after 10 years, even through in any one year the return may be unpredictable. Thus invest in CSR shares will have a low risk of capital loss over 10 years even it may have a higher risk over any one year.
Now you might ask the question why should we choice higher risk investment products if we have alternatively, lower risk investment products. The answer is because return on investment varies. |
