This project is inspired by Bogleheads forum. Bogleheads focus on a simple but powerful philosophy that allows investors to achieve above-average returns after costs. This tool is build around the same principles to help an average investor manage their investing portfolio.

Lakshmi (meaning "She who leads to one's goal") is one of the principal goddesses in Hinduism. She is the goddess of wealth, fortune, power, health, love, beauty, joy and prosperity.


This project consists of a library module (lakshmi) and a command-line tool (lak) that exposes some of the functionality of the library. The library provides useful abstractions and tools to manage your investing portfolio.

Bogleheads wiki is a great resource for introduction to basic investing concepts like asset-allocation, asset-location, etc.

The following features are currently available:

  • Specify and track asset allocation across accounts.
  • Ability to add/edit/delete accounts and assets (funds, stocks, etc.) inside those accounts.
  • Supports manual assets, assets with ticker, Vanguard funds (that don't have associated ticker symbols), EE Bonds and I Bonds.
  • Automatic fetching of market value of various types of assets.
  • Listing current values of assets, printing detailed information, printing asset allocation, asset location, etc.
  • Tracking of tax-lot information for assets.
  • Support for running what-if scenarios to see how it impacts the asset allocation, etc.
  • Analysis of portfolio to identify if there is need to rebalance or if there are losses that can be harvested.


This project can be installed via pip. To install the library and the lak command line tool, run:

pip install lakshmi

Accounts (His/Her 401(k), Roth IRAs, Taxable, etc.) can be added via the lak add account command:

$ lak add account
# Use the above command multiple times to add more accounts.

Assets can be added to an account via the lak add asset command. Different kinds of assets can be added to a portfolio. For a complete list, pull up the help for the command:

TickerAsset represents an asset with a ticker symbol. The value of these assets is pulled and updated automatically. To add a TickerAsset:

lak add asset -p TickerAsset -t account_str

where account_str is a sub-string that uniquely matches an account added previously.

That's it. To view all the assets, asset allocation and asset location, run:

lak list assets total aa al
