Beside above, how do you calculate attribution? How to Calculate Performance Attribution

1. Locate Sector Weights and Returns of the Portfolio.
2. Multiply Sector Weights by Differences in Returns.
3. Calculate Aggregate Estimate for Pure Sector Allocation.
4. Calculate Sector Weights by Differences in Returns.
5. Calculate Aggregate Estimate for Returns.
6. Multiply Benchmark Weight by Difference in Returns.

In this manner, what is the difference between contribution and attribution?

Attribution” is the idea that a change is solely due to your intervention. “Contribution” is the idea that your influence is just one of many factors which contribute to a change.

What is interaction effect in attribution?

### What is the allocation effect?

1. Allocation Effect. Measuring ability of an investment manager to allocate the assets of a portfolio to different segments. The allocation effect determines whether the overweighting or under weighting of sectors relative to a benchmark contributes negatively or positively to an account's overall return.

It analyses the effect of the internal and the external factors in the contribution. It estimates the direct variable costs and the selling price of a range of products.

### How do you calculate alpha?

Alpha is an index which is used for determining the highest possible return with respect to the least amount of the risk and according to the formula, alpha is calculated by subtracting the risk-free rate of the return from the market return and multiplying the resultant with the systematic risk of the portfolio

### How are contributions to returns calculated?

The contribution calculation is done by multiplying each sector's weight by its return, and then summing the results.

1. The overall benchmark (or "notional portfolio").
2. The sector that the security forms part of, within the benchmark.

### What is Sharpe ratio in mutual fund?
