Efficient Frontier

This tutorial uses the MeanRisk optimization to find an ensemble of portfolios belonging to the Mean-Variance efficient frontier (pareto font).

Data

We load the S&P 500 dataset composed of the daily prices of 20 assets from the S&P 500 Index composition starting from 1990-01-02 up to 2022-12-28:

import numpy as np
from plotly.io import show
from sklearn.model_selection import train_test_split

from skfolio import PerfMeasure, RatioMeasure, RiskMeasure
from skfolio.datasets import load_sp500_dataset
from skfolio.optimization import MeanRisk
from skfolio.preprocessing import prices_to_returns

prices = load_sp500_dataset()

X = prices_to_returns(prices)
X_train, X_test = train_test_split(X, test_size=0.33, shuffle=False)

Model

We create the Mean-Variance model and then fit it on the training set. The parameter efficient_frontier_size=30 is used to find 30 portfolios on the entire efficient frontier:

model = MeanRisk(
    risk_measure=RiskMeasure.VARIANCE,
    efficient_frontier_size=30,
    portfolio_params=dict(name="Variance"),
)
model.fit(X_train)
print(model.weights_.shape)

(30, 20)

Prediction

We predict this model on both the training set and the test set. The predict method returns the Population of 30 Portfolio:

population_train = model.predict(X_train)
population_test = model.predict(X_test)

Analysis

For improved analysis, we add a “Train” and “Test” tag to the portfolios and concatenate the training and the test populations:

population_train.set_portfolio_params(tag="Train")
population_test.set_portfolio_params(tag="Test")

population = population_train + population_test

fig = population.plot_measures(
    x=RiskMeasure.ANNUALIZED_VARIANCE,
    y=PerfMeasure.ANNUALIZED_MEAN,
    color_scale=RatioMeasure.ANNUALIZED_SHARPE_RATIO,
    hover_measures=[RiskMeasure.MAX_DRAWDOWN, RatioMeasure.ANNUALIZED_SORTINO_RATIO],
)
show(fig)

Let’s plot the composition of the 30 portfolios:

population_train.plot_composition()

Let’s print the Sharpe Ratio of the 30 portfolios on the test set:

population_test.measures(measure=RatioMeasure.ANNUALIZED_SHARPE_RATIO)

array([0.91785162, 0.93000375, 0.9401232 , 0.95027284, 0.96861483,
       0.98463685, 0.9983657 , 1.00992555, 1.01943433, 1.02702131,
       1.032813  , 1.03704654, 1.03993049, 1.04204356, 1.0430764 ,
       1.04289017, 1.04158213, 1.03774863, 1.02943678, 1.02092595,

       0.78090544, 0.68550154, 0.59858003, 0.53398775, 0.55455742])

Finally, we can show a full summary of the 30 portfolios evaluated on the test set:

Instead of providing efficient_frontier_size=30, you can also provide an array of lower bounds for the expected returns using min_return. In the below example, we find the 5 portfolios that minimize the variance under a minimum return constraint of 15%, 20%, 25%, 30% and 35% (annualized):

model = MeanRisk(
    risk_measure=RiskMeasure.VARIANCE,
    min_return=np.array([0.15, 0.20, 0.25, 0.30, 0.35]) / 252,
    portfolio_params=dict(name="Variance"),
)

population = model.fit_predict(X_train)

population.plot_measures(
    x=RiskMeasure.ANNUALIZED_VARIANCE,
    y=PerfMeasure.ANNUALIZED_MEAN,
    color_scale=RatioMeasure.ANNUALIZED_SHARPE_RATIO,
    hover_measures=[RiskMeasure.MAX_DRAWDOWN, RatioMeasure.ANNUALIZED_SORTINO_RATIO],
)
