Invest alongside me

I don’t just write about these companies — I invest in them. My Wikifolio is where I put the research and investment approach you read about here into practice, with a concentrated portfolio built for the long term.

Current investments include Arista Networks, Alphabet, ASML, AMD, Booking, and others.

https://www.wikifolio.com/de/de/w/wfinvest41

How I measure buys and sells:

I only take buy and sell decisions that surpassed a certain threshold: I am not interested if a fund manager sells 5% of his 31st largest holding. I am focusing on the changes that have a real impact on the fund.

The buys

There was a clear winner in terms of buys: Mastercard

Three different fund managers had Mastercard on their shopping list in Q2. Mastercard is a fantastic company, and it's rare to be able to buy it at a relative discount. Mastercard is never a cheap company, but the business justifies the premium.

Chart preview

For this very reason, I also published an article on Mastercard. I am happy that I bought shares, and I hope some of you did so as well. In this article, I also explain why Mastercard will continue to have a great future.

Invest at your own risk; this is not financial advice! This is not a recommendation to buy or sell any securities discussed in the article.

You can see that there was no clear runaway favorite amongst the top fund managers that I follow. No other position apart from Mastercard had more than two individual fund managers as buyers.

There is a clear theme on financial-related companies finally selling for a discount: Mastercard, Visa, and S&P Global.

As usual, some of the Mag7 found their way into the portfolios, namely Microsoft and Amazon.
