The post is brought to you by me.

If you’re going to invest in LEGO, you need to keep track of your investments.

Look no further than my LEGO Investing Portfolio Tracker.

This is a spreadsheet created by Anthony (a newsletter subscriber & mongo927 on Discord) that helps you become a more organized and responsible investor.

It automatically calculates everything you need to know about how well your investments are performing.

For a small one-time fee, you get lifetime access to all future updates so you can stay organized and confident about your investments:

IMPORTANT: A SPREADSHEET VERSION OF THE HIT LIST IS LINKED AT THE BOTTOM OF THIS POST

The hit list you are about to see below is the list of LEGO sets my set picking system likes most for investing this year.

If these sets remain on the list in October, I will be buying tons of them in the months to follow.

It is created by:

  1. Looking at a giant list of sets expected to retire

  2. Inputting Amazon sales rank data (i.e. demand) into my custom set picking system and letting it spit out which sets it thinks will perform best

  3. Picking demand thresholds for each theme to adhere to based on prior performance and estimated supply data

Every month the list is updated by adding in the prior month’s demand data from Amazon.

Does this system catch ALL of the best sets every year? No.

However, it has outperformed the average for the last three years by a mile.

*** Today’s update is an important one because I have now added in 2024 retiree data to my system and it has resulted in a few changes ***

The format below for listing hit list sets is as follows:

  • Theme

    • List of sets my system likes

Let’s dive in.
