QuantStats: Portfolio analytics for quants

QuantStats Python library that performs portfolio profiling, allowing quants and portfolio managers to understand their performance better by providing them with in-depth analytics and risk metrics.

Changelog »

QuantStats is comprised of 3 main modules:

  1. quantstats.stats - for calculating various performance metrics, like Sharpe ratio, Win rate, Volatility, etc.

  2. quantstats.plots - for visualizing performance, drawdowns, rolling statistics, monthly returns, etc.

  3. quantstats.reports - for generating metrics reports, batch plotting, and creating tear sheets that can be saved as an HTML file.

Here’s an example of a simple tear sheet analyzing a strategy:

Quick Start

%matplotlib inline
import quantstats as qs

# extend pandas functionality with metrics, etc.
qs.extend_pandas()

# fetch the daily returns for a stock
stock = qs.utils.download_returns('FB')

# show sharpe ratio
qs.stats.sharpe(stock)

# or using extend_pandas() :)
stock.sharpe()

Output:

0.8135304438803402

Visualize stock performance

qs.plots.snapshot(stock, title='Facebook Performance')

# can also be called via:
# stock.plot_snapshot(title='Facebook Performance')

Output:

Snapshot plot

Creating a report

You can create 7 different report tearsheets:

  1. qs.reports.metrics(mode='basic|full", ...) - shows basic/full metrics

  2. qs.reports.plots(mode='basic|full", ...) - shows basic/full plots

  3. qs.reports.basic(...) - shows basic metrics and plots

  4. qs.reports.full(...) - shows full metrics and plots

  5. qs.reports.html(...) - generates a complete report as html

Let’ create an html tearsheet

(benchmark can be a pandas Series or ticker)
qs.reports.html(stock, "SPY")

Output will generate something like this:

HTML tearsheet

*** Full documenttion coming soon ***

In the meantime, you can get insights as to optional parameters for each method, by using Python’s help method:

help(qs.stats.conditional_value_at_risk)
Help on function conditional_value_at_risk in module quantstats.stats:

conditional_value_at_risk(returns, sigma=1, confidence=0.99)
    calculats the conditional daily value-at-risk (aka expected shortfall)
    quantifies the amount of tail risk an investment

Installation

Install using pip:

$ pip install quantstats --upgrade --no-cache-dir

Install using conda:

$ conda install -c ranaroussi quantstats

Requirements

Questions?

This is a new library… If you find a bug, please open an issue in this repository.

If you’d like to contribute, a great place to look is the issues marked with help-wanted.

Known Issues

For some reason, I couldn’t find a way to tell seaborn not to return the monthly returns heatmap when instructed to save - so even if you save the plot (by passing savefig={...}) it will still show the plot.

P.S.

Please drop me a note with any feedback you have.
