# 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.md)

### 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.

---

### **NEW! Monte Carlo Simulations**

<img src="https://raw.githubusercontent.com/ranaroussi/pandas-montecarlo/master/demo.png" alt="Monte Carlo Simulation" width="640">

Run probabilistic risk analysis with built-in Monte Carlo simulations:

```python
mc = qs.stats.montecarlo(returns, sims=1000, bust=-0.20, goal=0.50)
print(f"Bust probability: {mc.bust_probability:.1%}")
print(f"Goal probability: {mc.goal_probability:.1%}")
mc.plot()
```

[Full Monte Carlo documentation »](./docs/montecarlo.md)

---

## Quick Start

```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:

```
0.7604779884378278
```

### Visualize stock performance

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

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

Output:

![Snapshot plot](https://github.com/ranaroussi/quantstats/blob/main/docs/snapshot.webp?raw=true)

### 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's create an html tearsheet:

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

Output will generate something like this:

![HTML tearsheet](https://github.com/ranaroussi/quantstats/blob/main/docs/report.webp?raw=true)

### Important: Period-Based vs Trade-Based Metrics

QuantStats analyzes **return series** (daily, weekly, monthly returns), not discrete trade data. This means:

- **Win Rate** = percentage of periods with positive returns
- **Consecutive Wins/Losses** = consecutive positive/negative return periods
- **Payoff Ratio** = average winning period return / average losing period return
- **Profit Factor** = sum of positive returns / sum of negative returns

These metrics are **valid and useful** for:
- Systematic/algorithmic strategies with regular rebalancing
- Analyzing return-series behavior over time
- Comparing strategies on a period-by-period basis

For **discretionary traders** with multi-day trades, these period-based metrics may differ from trade-level statistics. A single 5-day trade might span 3 positive days and 2 negative days - QuantStats would count these as 3 "wins" and 2 "losses" at the daily level.

This is consistent with how all return-based analytics work (Sharpe ratio, Sortino ratio, drawdown analysis, etc.) - they operate on return periods, not discrete trade entries/exits.

---

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

```python
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)
    calculates 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).

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.
