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 » <./CHANGELOG.rst>`__

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
===========

.. code:: python

    %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('META')

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

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

Output:

.. code:: text

    0.8135304438803402


Visualize stock performance
~~~~~~~~~~~~~~~~~~~~~~~~~~~

.. code:: python

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

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

Output:

.. image:: https://github.com/ranaroussi/quantstats/blob/main/docs/snapshot.jpg?raw=true
    :alt: 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

.. code:: python

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

Output will generate something like this:

.. image:: https://github.com/ranaroussi/quantstats/blob/main/docs/report.jpg?raw=true
    :alt: 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:

.. code:: python

    help(qs.stats.conditional_value_at_risk)

.. code:: text

	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

Questions?
----------

This is a new library... If you find a bug, please
`open an issue <https://github.com/ranaroussi/quantstats/issues>`_
in this repository.

If you'd like to contribute, a great place to look is the
`issues marked with help-wanted <https://github.com/ranaroussi/quantstats/issues?q=is%3Aopen+is%3Aissue+label%3A%22help+wanted%22>`_.


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.
