1. What is expected return?
Expected return refers to the average expected return of an investor within a specific period of time, calculated based on a probability distribution. It takes into account all possible outcomes and their probability of occurrence and is a weighted average. The formula is as follows:
Expected return = Σ (yield × probability)
For example, a certain stock has three possible rates of return and their probabilities are as follows:
| Yield | Probability |
|---|---|
| 10% | 30% |
| 5% | 50% |
| -2% | 20% |
Expected return = (10% × 30%) + (5% × 50%) + (-2% × 20%) = 4.6%

1.Diversification: By combining different assets, the risk of a single asset is reduced and the overall expected return is increased.
2.risk assessment: Expected returns need to be analyzed together with risks (such as variance). For example:
| investment options | expected return | Risk (standard deviation) |
|---|---|---|
| Stock A | 8% | 15% |
| Bond B | 4% | 5% |
3.Dynamic adjustment: Update the probability distribution and revise the expected return based on market hot spots (such as recent artificial intelligence concept stocks).
4. Precautions
- Historical data does not equal future performance, and probabilities need to be combined with the latest information (such as policy changes).
- High expected returns may be accompanied by high risks, which need to be selected based on personal risk preference.
-Regular review and correction of assumptions in the calculation model.
