5 Underappreciated Substack Publications about Investing

5 of my favorite under the radar Substack publications

In the crowded world of investment advice, it can be easy to miss some hidden gems. Here are five underappreciated Substack publications that offer unique and valuable insights for serious long-term investors.

1. Rijnberk InvestInsights

Daan Rijnberk

is the brainchild of Rijnberk InvestInsights. Alex offers a mix of market updates, company deep dives, and personal investment strategies.

I especially liked the MercadoLibre deep dive. But he also talked about Starbucks, Booking, Meta Platforms and many others. He doesn’t just ‘upload’, he actually has something valuable to say, which is something I can only appreciate

I find the content to be accessible yet highly informative, making complex topics easier to understand. Despite its analytical depth and clear communication style, this Substack is still a hidden gem in the investment community.

2. Chit Chat Stocks

Chit Chat Stocks

, run by Ryan Henderson and Brett Schafer, is a lively and engaging platform for investing, market news, and investment tips. Their energetic style and passion for stocks make their posts both informative and entertaining. Not only do they write on Substack. They actually have one of my personal favorite podcast under the same brand name.

Chit Chat Stocks stands out for its accessibility, easy to understand, and community focus, aiming to create a space where readers can learn and share ideas in a friendly, supportive environment. Despite its high-quality content and growing readership, it still remains underappreciated in my personal opinion, compared to more established names in the field. Highly recommend following them on both Spotify and Substack.

3. Invest in Quality

I believe this Substack publication is very overlooked.

Invest in Quality

focuses on high-quality investment opportunities and long-term value. He talks about investing in businesses, how to find them, what to look for, interesting companies you might want to take a look at, give you tips about potential buys, and much more.

Quality and diligence are the pillars of Invest in Quality, advocating for investments that stand the test of time to ensure sustainable growth and stability. Worth a follow!

4. BusinessInvest

Business Invest

, authored by Francesco, offers in-depth analysis of business strategies, market dynamics, and investment opportunities. Francesco’s posts often feature detailed case studies, providing readers with a well-rounded perspective on the business. Some of its most popular posts can be seen in the image below.

Some publications feel ‘pushy’, don’t offer enough useful information, are 100% written by AI and overall, lack knowledge. This is not the case with this publication! When reading its article, it feels like he took the time and effort to research, write and make it easy to understand for readers. Something I can only appreciate. BusinessInvest remains lesser-known, making it a valuable but underappreciated resource for investors.

5. Sleep Well Investments

Honestly, one of my favorite mission quote’s I’ve found.

You deserve a portfolio that allows you to sleep-well!

It’s so well-thought-out! Alright, back to the point.

Trung Nguyen @SWIs

is run by Trung, a name you might recognize from his insightful contributions to X (formerly known as Twitter), Seeking Alpha, and various podcasts. Despite the high quality of its content, Sleep Well Investments remains under the radar for many investors. This is partly due to the sheer volume of investment advice available online, which can make it difficult for newer voices to gain traction.

Trung is dedicated to finding exceptional businesses through thorough, in-depth analysis—a mission we share. He practices what he preaches by actively investing in opportunities he identifies, sharing the rationale behind his buy or sell decisions with his paid members, and providing regular updates on those investments. His investment strategy aligns closely with ours, making Sleep Well Investments a hidden Substack gem that deserves a spot on our list!

Each offers unique insights and thorough analysis, making them worth following to improve your investment strategies and stay informed about market opportunities.
