Name: Stefan Thelenius @StefanThelenius
Age: 53
Residence: Stockholm, Sweden
Invests since: Started with swingtrading in 2001 and switched to long term investing in 2014.

𝗜𝗻𝘁𝗿𝗼𝗱𝘂𝗰𝘁𝗶𝗼𝗻
I have a technical background and worked as an R&D engineer in medical technology from 1994 to 2000, and since then, I have held various roles within software development. I switched direction in 2016 and have since been working as a consumer advisor in pension and insurance law.

I began stock swing trading in 2001 when a stock competition enticed me to open a stock account. The results were mixed, and after a few years, I ended up with a 40% loss in Ericsson. I then stayed out of the stock market until 2009. Between 2009 and 2014, I dedicated myself to swing trading in indices. The result was mediocre, and I found it difficult to sleep well at night when holding overnight positions in indices. In 2014, I finally started investing long-term and more seriously. Initially, it was 100% dividend investing, and after the pandemic crash in 2020, I transitioned to growth stock investing.

My current investment goals are as follows:
- Joyfulness: reporting season is fun for me and also exciting.
- Educational: I love to read and learn about new stuff like semiconductor technology, AI, health technology, etc.
- Sleeping well at night: diversification for the win!
- Achieving over 15% CAGR over time. Current result approximately 13% CAGR since 2014.
