**yfinance** offers a threaded and Pythonic way to download market data from [Yahoo!Ⓡ finance](https://finance.yahoo.com).

→ Check out this [Blog post](https://aroussi.com/#post/python-yahoo-finance) for a detailed tutorial with code examples.

[Changelog »](https://github.com/ranaroussi/yfinance/blob/main/CHANGELOG.rst)

---

## Quick Start

### The Ticker module

The `Ticker` module, which allows you to access ticker data in a more Pythonic way:

```python
import yfinance as yf

msft = yf.Ticker("MSFT")

# get all stock info
msft.info

# get historical market data
hist = msft.history(period="1mo")

# show meta information about the history (requires history() to be called first)
msft.history_metadata

# show actions (dividends, splits, capital gains)
msft.actions
msft.dividends
msft.splits
msft.capital_gains  # only for mutual funds & etfs

# show share count
msft.get_shares_full(start="2022-01-01", end=None)

# show financials:
# - income statement
msft.income_stmt
msft.quarterly_income_stmt
# - balance sheet
msft.balance_sheet
msft.quarterly_balance_sheet
# - cash flow statement
msft.cashflow
msft.quarterly_cashflow
# see `Ticker.get_income_stmt()` for more options

# show holders
msft.major_holders
msft.institutional_holders
msft.mutualfund_holders

# Show future and historic earnings dates, returns at most next 4 quarters and last 8 quarters by default. 
# Note: If more are needed use msft.get_earnings_dates(limit=XX) with increased limit argument.
msft.earnings_dates

# show ISIN code - *experimental*
# ISIN = International Securities Identification Number
msft.isin

# show options expirations
msft.options

# show news
msft.news

# get option chain for specific expiration
opt = msft.option_chain('YYYY-MM-DD')
# data available via: opt.calls, opt.puts
```

If you want to use a proxy server for downloading data, use:

```python
import yfinance as yf

msft = yf.Ticker("MSFT")

msft.history(..., proxy="PROXY_SERVER")
msft.get_actions(proxy="PROXY_SERVER")
msft.get_dividends(proxy="PROXY_SERVER")
msft.get_splits(proxy="PROXY_SERVER")
msft.get_capital_gains(proxy="PROXY_SERVER")
msft.get_balance_sheet(proxy="PROXY_SERVER")
msft.get_cashflow(proxy="PROXY_SERVER")
msft.option_chain(..., proxy="PROXY_SERVER")
...
```

### Multiple tickers

To initialize multiple `Ticker` objects, use

```python
import yfinance as yf

tickers = yf.Tickers('msft aapl goog')

# access each ticker using (example)
tickers.tickers['MSFT'].info
tickers.tickers['AAPL'].history(period="1mo")
tickers.tickers['GOOG'].actions
```

To download price history into one table:

```python
import yfinance as yf
data = yf.download("SPY AAPL", period="1mo")
```

#### `yf.download()` and `Ticker.history()` have many options for configuring fetching and processing. [Review the Wiki](https://github.com/ranaroussi/yfinance/wiki) for more options and detail.

### Logging

`yfinance` now uses the `logging` module to handle messages, default behaviour is only print errors. If debugging, use `yf.enable_debug_mode()` to switch logging to debug with custom formatting.

### Smarter scraping

To use a custom `requests` session (for example to cache calls to the
API or customize the `User-agent` header), pass a `session=` argument to
the Ticker constructor.

```python
import requests_cache
session = requests_cache.CachedSession('yfinance.cache')
session.headers['User-agent'] = 'my-program/1.0'
ticker = yf.Ticker('msft', session=session)
# The scraped response will be stored in the cache
ticker.actions
```

Combine a `requests_cache` with rate-limiting to avoid triggering Yahoo's rate-limiter/blocker that can corrupt data.
```python
from requests import Session
from requests_cache import CacheMixin, SQLiteCache
from requests_ratelimiter import LimiterMixin, MemoryQueueBucket
from pyrate_limiter import Duration, RequestRate, Limiter
class CachedLimiterSession(CacheMixin, LimiterMixin, Session):
    pass

session = CachedLimiterSession(
    limiter=Limiter(RequestRate(2, Duration.SECOND*5)),  # max 2 requests per 5 seconds
    bucket_class=MemoryQueueBucket,
    backend=SQLiteCache("yfinance.cache"),
)
```

### Managing Multi-Level Columns

The following answer on Stack Overflow is for [How to deal with
multi-level column names downloaded with
yfinance?](https://stackoverflow.com/questions/63107801)

-   `yfinance` returns a `pandas.DataFrame` with multi-level column
    names, with a level for the ticker and a level for the stock price
    data
    -   The answer discusses:
        -   How to correctly read the the multi-level columns after
            saving the dataframe to a csv with `pandas.DataFrame.to_csv`
        -   How to download single or multiple tickers into a single
            dataframe with single level column names and a ticker column

### `pandas_datareader` override

If your code uses `pandas_datareader` and you want to download data
faster, you can "hijack" `pandas_datareader.data.get_data_yahoo()`
method to use **yfinance** while making sure the returned data is in the
same format as **pandas\_datareader**'s `get_data_yahoo()`.

```python
from pandas_datareader import data as pdr

import yfinance as yf
yf.pdr_override() # <== that's all it takes :-)

# download dataframe
data = pdr.get_data_yahoo("SPY", start="2017-01-01", end="2017-04-30")
```

### Timezone cache store

When fetching price data, all dates are localized to stock exchange timezone. 
But timezone retrieval is relatively slow, so yfinance attemps to cache them 
in your users cache folder. 
You can direct cache to use a different location with `set_tz_cache_location()`:
```python
import yfinance as yf
yf.set_tz_cache_location("custom/cache/location")
...
```

## Installation

Install `yfinance` using `pip`:

``` {.sourceCode .bash}
$ pip install yfinance --upgrade --no-cache-dir
```

Test new features by installing betas, provide feedback in [corresponding Discussion](https://github.com/ranaroussi/yfinance/discussions):
``` {.sourceCode .bash}
$ pip install yfinance --upgrade --no-cache-dir --pre
```
