I am Trung. I write 10+K words deep-dives on market leaders. I also write Thesis Trackers updates to follow up on their performance. When the right price comes, I buy them for the Sleep Well Portfolio, which I am building for my 4-year-old daughter to redeem in 2037. I disclose the reasoning of all BUY and SELL (ideally never) transactions (1st, 2nd, and 3rd). Join me in building generational wealth.


This is the sixth pick. It is the smallest company I have researched with less than $1 billion market cap (19% CAGR since IPO and 26% CAGR in the past ten years). However, it has the strongest market position with an 80% share of the penetrated markets and impenetrable moats that, in the last 30 years, competitors have yet to disrupt their market share growth. It also has plenty of reinvestment opportunities to double earnings in five years.

You can expect a thorough analysis of the following:

  1. What is the business?

  2. Why is it a sleep-well investment?

    1. How it carved out a niche since 1984

    2. 40/60 Razor-blade business model

    3. Unchallenged monopolistic position

    4. Reinvestment opportunities

    5. Lacksture competition

    6. Seasoned management

  3. Key risks and what to look out for?

  4. What is the fair price?

  5. Sleep Well Investment scorecard.
