Passive Investing for the Average Joe.

The Passive Investor

Theories and research about the stock market have stated that the semi-strong form of market efficiency seems to hold. This means that all public information is accurately reflected in the price of a financial instrument. This makes the job of a portfolio manager primarily managing the desired risk appetite of the client and not explicitly trying to outperform the market. This fact in combination with Finance professionals all around the world looking for that 'edge' to make their investment decisions as profitable as possible, makes it so the average joe can not compete.

Therefore, the term 'Passive Investing' is often coined around. This refers to buying funds (either ETFs or Mutual Funds) that follow the index (i.e. S&P 500, Dow Jones Index) or a broad market (Developed Markets, MSCI World) for diversification benefits. This means that a sudden decrease in performance of one stock within the index does not (on average) lead to a significant decline in the index as a whole. This allows the holder to spend limited time monitoring his holdings, therefore the term 'Passive'.

With a large increase in ETFs available (over 5,000 in 2020), it can become difficult to make the best choice in what you wish to invest. There are many different providers (iShares, Vanguard, Invesco) as well as with changes to the underlying stocks (i.e. High Yield, Super Dividends, Equal Weighted). This is quickly reflected when looking for a S&P 500 ETF as there are over 20 different ETFs available. With this package, I wish to make investment decisions easier to make and manage.

An example of the output can be found in the GIF below. This depicts several ETFs collected from the Top ETFs according to Yahoo Finance.

Installation

The package can be installed via the following commands:

1. pip install thepassiveinvestor
   • Alternatively, download this repository.
2. (within Python) import thepassiveinvestor as pi

The functions within this package are:

• collect_data(ticker) - collects the most important data for ETFs as listed in the Functionality section.
• create_ETF_report(tickers, filename, folder=None) - uses collect_data to create an Excel report with data, as depicted in the GIF above, per sheet for each ticker.

Therefore, if you wish to collect data on an ETF or create a report of a selection of ETFs you can use the following example:

import thepassiveinvestor as pi

# Collect data from a specific ETF
vanguard_sp500 = pi.collect_data('VOO')

# Show the data
vanguard_sp500

Which returns the following:

You also have the option to generate a comparison report as follows:

import thepassiveinvestor as pi

# Collect data from a set of ETFs and compare them
etf_comparison = pi.collect_data(['VOO', 'QQQ', 'ARKG', 'VUG', 'SCHA', 'VWO'], comparison=True)

# Show the comparison
etf_comparison

Which returns the following:

Lastly, if you wish to export to Excel this is also a possibility generating an Excel file that contains the most relevant information for each ticker.

import thepassiveinvestor as pi

# Create a report from a list of ETFs
etf_list = ['VOO', 'QQQ', 'ARKG', 'VUG', 'SCHA', 'VWO']
pi.create_ETF_report(etf_list, 'Popular ETFs.xlsx')

Which returns the following:

Functionality
