Netflix (4 pcs.) in 2015. Had to sell them again in the same year due to debt (already with a decent profit). I'm still annoyed today that I sold them. Edit: There was even a 1:4 stock split shortly after the purchase. So I ended up selling 16 shares.
On January 23, 2017, I got off to a flying start and opened several positions. Nestle, Bayer, Daimler and my lucky strike. Which has developed into the largest position and is the only share that has remained in the portfolio.
1987 Siemens and Schering warrant, which was recommended by a completely new paper, Börse online 😅. The warrant went well although I didn't know what it was 🤷♂️😂. Siemens came under the wheels on Black Monday and was sold frantically
2014: $TSLA and $MBTN Made a lot of money with Tesla. Today, however, I would no longer touch this share. Meyer Burger, on the other hand, was practically a total loss😂
