Call for Contributors to the FinanceDatabase
The FinanceDatabase serves the role of providing anyone with any type of financial product categorisation entirely for free. To be able to achieve this, the FinanceDatabase relies on involvement from the community to update, edit and remove tickers over time. This is made easy enough that anyone, even with a lack of coding experience can contribute because of the usage of CSV files that can be manually edited.
I'd like to invite you to go to the Contributing Guidelines to understand how you can help. Thank you!

As a private investor, the sheer amount of information that can be found on the internet is rather daunting. Trying to understand what type of companies or ETFs are available is incredibly challenging with there being millions of companies and derivatives available on the market. Sure, the most traded companies and ETFs can quickly be found simply because they are known to the public (for example, Microsoft, Tesla, S&P500 ETF or an All-World ETF). However, what else is out there is often unknown.

This database tries to solve that. It features 300.000+ symbols containing Equities, ETFs, Funds, Indices, Currencies, Cryptocurrencies and Money Markets. It therefore allows you to obtain a broad overview of sectors, industries, types of investments and much more.

The aim of this database is explicitly not to provide up-to-date fundamentals or stock data as those can be obtained with ease (with the help of this database) by using yfinance or FundamentalAnalysis. Instead, it gives insights into the products that exist in each country, industry and sector and gives the most essential information about each product. With this information, you can analyse specific areas of the financial world and/or find a product that is hard to find. See for examples on how you can combine this database, and the earlier mentioned packages the section Examples.

Some key statistics of the database:

Product	Quantity	Sectors	Industries	Countries	Exchanges
Equities	155.705	16	242	111	82
ETFs	36.727	364*	94*	100**	52
Funds	57.816	1678*	438*	100**	34

Product	Quantity	Category
Currencies	2.590	174 Currencies
Cryptocurrencies	3.624	299 Cryptocurrencies
Indices	86.353	49 Exchanges
Money Markets	1.384	2 Exchanges

* These numbers refer to families (iShares, Vanguard) and categories (World Stock, Real Estate) respectively.
** This is an estimation. Obtaining the country distribution can only be done by collecting data on the underlying or by manual search.

Installation

The package financedatabase allows you to select specific json files as well as search through collected data with a specific query.

You can install the package with the following steps:

1. pip install financedatabase
2. (within Python) import financedatabase as fd

Basic Usage

This section explains in detail how the database can be queried with the related financedatabase package, also see the Jupyter Notebook in which you can run the examples also demonstrated here. You can find this document here.

Quick Start

Same methods apply to all other asset classes as well. Columns may vary.

import financedatabase as fd

# Initialize the Equities database
equities = fd.Equities()

# Obtain all countries from the database
equities_countries = equities.options('country')

# Obtain all sectors from the database
equities_sectors = equities.options('sector')

# Obtain all industries from a country from the database
equities_germany_industries = equities.options('industry', country='Germany')

# Obtain a selection from the database
equities_united_states = equities.select(country="United States")

# Obtain a detailed selection from the database
equities_usa_consumer_electronics = equities.select(country="United States", industry="Consumer Electronics")

# Search specific fields from the database
equities_uk_biotech = equities.search(country='United Kingdom', summary='biotech', exchange='LSE')

Scroll down below for a more elaborate explanation and detailed examples.

Collecting information from the database

Please see the Jupyter Notebook for an elaborate explanation of each asset class. This includes Equities, ETFs, Funds, Indices, Currencies, Cryptocurrencies and Money Markets.

As an example for Equities, If you wish to collect data from all equities you can use the following:

import financedatabase as fd

# Initialize the Equities database
equities = fd.Equities()

# Obtain all data available excluding international exchanges
equities.select()

Which returns the following DataFrame:

symbol	short_name	long_name	currency	sector	industry_group	industry	exchange	market	country	state	city	zipcode	website	market_cap

AABB	ASIA BROADBAND INC	Asia Broadband, Inc.	USD	Materials	Materials	Metals & Mining	PNK	us_market	United States	NV	Las Vegas	89135	http://www.asiabroadbandinc.com	Micro Cap

This returns approximately 20.000 different equities. Note that by default, only the American exchanges are selected. These are symbols like TSLA (Tesla) and MSFT (Microsoft) that tend to be recognized by a majority of data providers and therefore is the default. To disable this, you can set the exclude_exchanges argument to False which then results in approximately 155.000 different symbols.

Note that the summary column is taken out on purpose to keep it organized for markdown. The summary is however very handy when it comes to querying specific words as found with the following description given for Apple. All of this information is available when you query the database.

Help on method select in module financedatabase.equities:

select(country: str = '', sector: str = '', industry: str = '', exclude_exchanges: bool = True, capitalize: bool = True) -> pandas.core.frame.DataFrame method of financedatabase.equities.Equities instance
    Description
    ----
    Returns all equities when no input is given and has the option to give
    a specific set of symbols for the country, sector and/or industry provided.
    
    The data depends on the combination of inputs. For example Country + Sector
    gives all symbols for a specific sector in a specific country.
    
    Input
    ----
    country (string, default is None)
        If filled, gives all data for a specific country.
    sector (string, default is None)
        If filled, gives all data for a specific sector.
    industry (string, default is None)
        If filled, gives all data for a specific industry.
    exclude_exchanges (boolean, default is True):
        Whether you want to exclude exchanges from the search. If False,
        you will receive multiple times the product from different exchanges.
    capitalize (boolean, default is True):
        Whether country, sector and industry needs to be capitalized. By default
        the values always are capitalized as that is also how it is represented
        in the csv files.
    base_url (string, default is GitHub location)
        The possibility to enter your own location if desired.
    use_local_location (string, default False)
        The possibility to select a local location (i.e. based on Windows path)
    
    Output
    ----
    equities_df (pd.DataFrame)
        Returns a dictionary with a selection or all data based on the input.

As an example, we can use equities.options to obtain specific country, sector and industry options. For we can acquire all industries within the sector Basic Materials within the United States. This allows us to look at a specific industry in the United States in detail.

industry_options = equities.options(selection='industry', country="United States", sector="Materials")

So with this information in hand, I can now query the industry Metals & Mining as follows:

metals_and_mining_companies_usa = equities.select(country="United States", sector="Materials", industry="Metals & Mining")

This gives you a DataFrame with the following information:

symbol	short_name	long_name	currency	sector	industry_group	industry	exchange	market	country	state	city	zipcode	website	market_cap
AA	Alcoa Corporation	Alcoa Corporation	USD	Materials	Materials	Metals & Mining	NYQ	us_market	United States	PA	Pittsburgh	15212-5858	http://www.alcoa.com	Mid Cap
AABB	ASIA BROADBAND INC	Asia Broadband, Inc.	USD	Materials	Materials	Metals & Mining	PNK	us_market	United States	NV	Las Vegas	89135	http://www.asiabroadbandinc.com	Micro Cap
AAGC	ALL AMERICAN GOLD CORP	All American Gold Corp.	USD	Materials	Materials	Metals & Mining	PNK	us_market	United States	WY	Cheyenne	82001	http://www.allamericangoldcorp.com	Nano Cap
ABML	AMERICAN BATTERY METALS CORP NE	American Battery Metals Corporation	USD	Materials	Materials	Metals & Mining	PNK	us_market	United States	NV	Incline Village	89451	http://www.batterymetals.com	Small Cap
ACNE	ALICE CONS MINES INC	Alice Consolidated Mines, Inc.	USD	Materials	Materials	Metals & Mining	PNK	us_market	United States	ID	Wallace	83873-0469	nan	nan

As you can imagine, looking at such a specific selection only yields a few results but picking the entire sector Materials would have returned 403 different companies (which excludes exchanges other than the United States).

Searching the database extensively

All asset classes have the capability to search each column with search, for example equities.search(). Through how this functionality is developed you can define multiple columns and search throughoutly. For example:

# Collect all Equities Database
equities = fd.Equities()

# Search Multiple Columns
equities.search(summary='automotive', currency='USD', country='Germany')

Which returns a selection of the DataFrame that matches all criteria.

symbol	short_name	long_name	currency	sector	industry_group	industry	exchange	market	country	state	city	zipcode	website	market_cap
AFRMF	ALPHAFORM AG	Alphaform AG	USD	Industrials	Capital Goods	Machinery	PNK	us_market	Germany	nan	Feldkirchen	85622	nan	Nano Cap

BDRFF	BEIERSDORF AG	Beiersdorf Aktiengesellschaft	USD	Consumer Staples	Household & Personal Products	Household Products	PNK	us_market	Germany	nan	Hamburg	20245	http://www.beiersdorf.com	Large Cap

Storing the database at a different location

If you wish to store the database at a different location (for example your own Fork) you can do so with the variable base_url which you can find in each of the above 'select' functions. An example would be:

• fd.Equities(base_url=<YOUR URL>)

You can also store the database locally and point to your local location with the variable base_url and by setting use_local_location to True. An example would be:

• fd.Equities(base_url=<YOUR PATH>, use_local_location=True)

Examples

This section gives a few examples of the possibilities with this package. These are merely a few of the things you can do with the package. As you can obtain a wide range of symbols, pretty much any package that requires symbols should work.

Companies in the Netherlands

I want to see how many companies exist in each sector in the Netherlands. Let's count all companies with the following code, I skip a sector when it has no data and also do not include companies that are not categorized:

import financedatabase as fd

equities = fd.Equities()

equities_per_sector_netherlands = {}

for sector in equities.options(selection='sector', country='Netherlands'):
    try:
        equities_per_sector_netherlands[sector] = len(equities.select(country='Netherlands', sector=sector))
    except ValueError as error:
        print(error)

Lastly, I plot the data in a pie chart and add some formatting to make the pie chart look a bit nicer:

import matplotlib.pyplot as plt

legend, values = zip(*equities_per_sector_netherlands.items())

colors = ['b', 'g', 'r', 'c', 'm', 'y', 'k', 'tab:blue', 'tab:orange', 'tab:gray',
          'lightcoral', 'yellow', 'saddlebrown', 'lightblue', 'olive']
plt.pie(values, labels=legend, colors=colors,
        wedgeprops={'linewidth': 0.5, 'edgecolor': 'white'})
plt.title('Companies per sector in the Netherlands')
plt.tight_layout()

plt.show()

This results in the following graph which gives an indication which sectors are dominant within The Netherlands. Of course this is a mere example and to truly understand the importance of certain companies for the Netherlands, you would need to know market cap of each sector as well including demographics.

Technical Analysis of Biotech ETFs

With the help of ta and yfinance I can quickly perform a basic technical analysis on a group of ETFs categorized by the FinanceDatabase. I start by searching the database for ETFs related to Health and then make a subselection by searching, in the collected database, for biotech-related ETFs:

import financedatabase as fd

etfs = fd.ETFs()

health_etfs_in_biotech = etfs.search(category='Health', summary='biotech')

Then, I collect stock data on each ticker and remove tickers that have no data in my chosen period. The period I have chosen shows the initial impact of the Coronacrisis on the financial markets.

import yfinance as yf

tickers = list(health_etfs_in_biotech['symbol'])

stock_data_biotech = yf.download(tickers, start="2020-01-01", end="2020-06-01")['Adj Close']
stock_data_biotech = stock_data_biotech.dropna(axis='columns')

Next up I initialise subplots and loop over all collected tickers. Here, I create a new temporary DataFrame that I fill with the adjusted close prices of the ticker as well as the Bollinger Bands. Then I plot the data in one of the subplots.

import pandas as pd
from ta.volatility import BollingerBands
import matplotlib.pyplot as plt

figure, axis = plt.subplots(4, 3)
row = 0
column = 0

for ticker in stock_data_biotech.columns:
    data_plot = pd.DataFrame(stock_data_biotech[ticker])
    long_name = health_etfs_in_biotech.loc[health_etfs_in_biotech.symbol == ticker, 'long_name'].iloc[0]

    indicator_bb = BollingerBands(close=stock_data_biotech[ticker], window=20, window_dev=2)

    data_plot['bb_bbm'] = indicator_bb.bollinger_mavg()
    data_plot['bb_bbh'] = indicator_bb.bollinger_hband()
    data_plot['bb_bbl'] = indicator_bb.bollinger_lband()

    axis[row, column].plot(data_plot)
    axis[row, column].set_title(long_name, fontsize=6)
    axis[row, column].set_xticks([])
    axis[row, column].set_yticks([])

    column += 1
    if column == 3:
        row += 1
        column = 0
        
figure.suptitle('Technical Analysis of Biotech ETFs during Coronacrisis')
figure.tight_layout()

This leads to the following graph which gives an indication whether Biotech ETFs were oversold or overbought and how this effect is neutralised (to some degree) in the months after. Read more about Bollinger Bands here.

Silicon Valley's Market Cap

If I want to understand which listed technology companies exist in Silicon Valley, I can collect all equities of the sector 'Technology' and then filter based on city to obtain all listed technology companies in 'Silicon Valley'. The city 'San Jose' is where Silicon Valley is located.

import financedatabase as fd

equities = fd.Equities()

silicon_valley = equities.search(sector='Technology', city='San Jose')

Then I start collecting data with the FundamentalAnalysis package. Here I collect the key metrics which include 57 different metrics (ranging from PE ratios to Market Cap).

import fundamentalanalysis as fa

API_KEY = "YOUR_API_KEY_HERE"
data_set = {}

for ticker in silicon_valley['symbol']:
    try:
        data_set[ticker] = fa.key_metrics(ticker, API_KEY, period='annual', limit=10)
    except Exception:
        continue

Then I make a selection based on the last 5 years and filter by market cap to compare the companies in terms of size with each other. This also causes companies that have not been listed for 5 years to be filtered out of my dataset. Lastly, I plot the data.

import pandas as pd
import matplotlib.pyplot as plt

years = ['2018', '2019', '2020', '2021', '2022']
market_cap = pd.DataFrame(index=years)

for ticker in data_set:
    try:
        data_years = []
        for year in years: 
            data_years.append(data_set[ticker].loc['marketCap'][year])
        market_cap[silicon_valley.loc[silicon_valley.symbol == ticker]['short_name'].iloc[0]] = data_years
    except Exception:
        continue

market_cap_plot = market_cap.plot.bar(stacked=True, rot=0, colormap='Spectral')
market_cap_plot.legend(prop={'size': 5.25}, loc='upper left')
plt.show()

This results in the graph displayed below which separates the small companies from the large companies. Note that this does not include all technology companies in Silicon Valley because most are not listed or are not included in the database of the FundamentalAnalysis package.

Questions & Answers

In this section you can find answers to commonly asked questions. In case the answer to your question is not here, consider creating an Issue.

• How is the data obtained?
  • The data is an aggregation of a variety of sources and is driven by the community to extend further.
• How can I contribute?
  • Please see the Contributing Guidelines. Thank you!
• Is there support for my country?
  • Yes, most likely there is as the database includes 111 countries. Please check here.
• How can I find out which countries, sectors and/or industries exists within the database without needing to check the database manually?
  • For this you can use the show_options function from the package attached to this database. Please see this example
• When I try collect data I notice that not all tickers return output, why is that?
  • Some tickers are merely holdings of companies and therefore do not really have any data attached to them. Therefore, it makes sense that not all tickers return data. If you are still in doubt, search the ticker on Google to see if there is really no data available. If you can't find anything about the ticker, consider updating the database by visiting the Contributing Guidelines.

Contribution

Please read more about how you can contribute to the Database by reading the Contributing Guidelines. Anyone can contribute as it requires minimal knowhow of working with GitHub or Git.
