Report

The Report class contains the methods for computing common metrics and storing them to files. The class is initialized with a list of portfolio values. These values should always start with the initial value of 1, otherwise the class will raise an error.

from areport import Report

report = Report([1.0, 1.1, 1.2])

ReportComparison

The ReportComparison class contains the methods for comparing multiple reports. The class is initialized with one Report that is treated as the portfolio, and a dictionary of other Report instances that are treated as benchmarks.

from areport import ReportComparison

report_comparison = ReportComparison(report, {'benchmark1': report1, 'benchmark2': report2})

Metrics

The common metrics can be retrieved using the following methods:

from areport import Report

report = Report([1.0, 1.1, 1.2])
report.get_metrics()

The same is also possible for the ReportComparison class:

from areport import ReportComparison

report_comparison = ReportComparison(report, {'benchmark1': report1, 'benchmark2': report2})
report_comparison.get_metrics()

If you want to save the metrics to a file, you can use the metrics_to_{format} method:

from areport import Report

report = Report([1.0, 1.1, 1.2])
report.metrics_to_csv('report.csv')
report.metrics_to_json('report.json')

The same is also possible for the ReportComparison class:

from areport import ReportComparison

report_comparison = ReportComparison(report, {'benchmark1': report1, 'benchmark2': report2})
report_comparison.metrics_to_csv('report_comparison.csv')
report_comparison.metrics_to_json('report_comparison.json')

Using with aplotly

This package can be combined with the aplotly package to create interactive plots. The aplotly package is a wrapper around the plotly package that simplifies the creation of plots. The useful attrbutes of the Report class are pf_values and dt_pf_values. Here is an example of how to use the aplotly package with the Report class to create the performance chart.

from aplotly.plots import plot_performance
from areport import Report

report = Report([1.0, 1.1, 1.2])

fig = plot_performance(
    report.performance_to_pct(report.dt_pf_values - 1)  # performance in percentage
    report.drawdown_to_pct(report.drawdown, report.dt_pf_values.index)  # drawdown in percentage
    performance_label="Test",
    drawdown_label="Test",
    xlabel="X",
)
fig.show()
