## Usage
### Empyrial Engine
```py
from empyrial import empyrial, Engineportfolio = Engine(
start_date = "2018-08-01",
portfolio = ["BABA", "PDD", "KO", "AMD","^IXIC"],
weights = [0.2, 0.2, 0.2, 0.2, 0.2], # equal weighting is set by default
benchmark = ["SPY"] # SPY is set by default
)empyrial(portfolio)
```### Use custom data
See doc [here](https://empyrial.gitbook.io/empyrial/using-custom-data) to learn how to do this.### Calendar Rebalancing
A portfolio can be rebalanced for either a specific time period or for specific dates using the ```rebalance``` option.#### Rebalance for Time Period
Time periods available for rebalancing are
```2y```, ```1y```, ```6mo```, ```quarterly```, ```monthly``````py
from empyrial import empyrial, Engineportfolio = Engine(
start_date = "2018-08-01",
portfolio = ["BABA", "PDD", "KO", "AMD","^IXIC"],
weights = [0.2, 0.2, 0.2, 0.2, 0.2], # equal weighting is set by default
benchmark = ["SPY"], # SPY is set by default
rebalance = "1y"
)empyrial(portfolio)
```#### Rebalance for Custom Dates
You can rebalance a portfolio by specifying a list of custom dates.
⚠️ When using custom dates, the first date of the list must correspond with the ```start_date``` and the last element should correspond to the ```end_date``` which is **today's date** by default.```py
from empyrial import empyrial, Engineportfolio = Engine(
start_date = "2018-08-01",
portfolio = ["BABA", "PDD", "KO", "AMD","^IXIC"],
weights = [0.2, 0.2, 0.2, 0.2, 0.2], # equal weighting is set by default
benchmark = ["SPY"], # SPY is set by default
rebalance = ["2018-06-09", "2019-01-01", "2020-01-01", "2021-01-01"]
)empyrial(portfolio)
```### Optimizer
The default optimizer is **equal weighting**. You can specify custom weights, if desired.```py
from empyrial import empyrial, Engineportfolio = Engine(
start_date = "2018-08-01",
portfolio = ["BABA", "PDD", "KO", "AMD","^IXIC"],
weights = [0.1, 0.3, 0.15, 0.25, 0.2], # custom weights
rebalance = "1y" # rebalance every year
)empyrial(portfolio)
```You can also use the **built-in optimizers**. There are 4 optimizers available:
- ```"EF"```: **Global Efficient Frontier** [Example](https://empyrial.gitbook.io/empyrial/optimization/global-efficient-frontier)
- ```"MEANVAR"```: **Mean-Variance** [Example](https://empyrial.gitbook.io/empyrial/optimization/mean-variance)
- ```"HRP"```: **Hierarchical Risk Parity** [Example](https://empyrial.gitbook.io/empyrial/optimization/hierarchical-risk-parity)
- ```"MINVAR"```: **Minimum-Variance** [Example](https://empyrial.gitbook.io/empyrial/optimization/minimum-variance)```py
from empyrial import empyrial, Engineportfolio = Engine(
start_date = "2018-08-01",
portfolio = ["BABA", "PDD", "KO", "AMD","^IXIC"],
optimizer = "EF",
rebalance = "1y" # rebalance every year
)portfolio.weights
```> Output:
```
[0.0, 0.0, 0.0348, 0.9652, 0.0]
```
We can see that the allocation has been optimized.### Risk Manager
3 Risk Managers are available:- **Max Drawdown**: ```{"Max Drawdown" : -0.3}``` [Example](https://empyrial.gitbook.io/empyrial/risk-management/max-drawdown)
- **Take Profit**: ```{"Take Profit" : 0.4}``` [Example](https://empyrial.gitbook.io/empyrial/risk-management/take-profit)
- **Stop Loss**: ```{"Stop Loss" : -0.2}``` [Example](https://empyrial.gitbook.io/empyrial/risk-management/stop-loss)```py
from empyrial import empyrial, Engineportfolio = Engine(
start_date = "2018-08-01",
portfolio= ["BABA", "PDD", "KO", "AMD","^IXIC"],
optimizer = "EF",
rebalance = "1y", # rebalance every year
risk_manager = {"Max Drawdown" : -0.2} # Stop the investment when the drawdown becomes superior to -20%
)empyrial(portfolio)
