As mentioned in my U.S. non-banking financial services update, Visa was next on the list of companies we’ll deep dive into the space, after FactSet and Farmer Mac. In December, I initiated an investment position in Visa, and as you can imagine, there’s no studying Visa without researching both Mastercard and American Express.
Last week, Mastercard’s valuation unexpectedly fell below the price we’d want to pay for its shares, after the Trump administration announced a 10% interest rate cap on credit cards. For transparency, earlier this morning, I initiated a position in Mastercard, and both companies now constitute a combined 11% weighting of the Jenga Fund.
While it might be easier for me to publish the research on just Visa alone, it would be beneficial for you (and me) to have both companies covered in the same deep dive. As a result, I’ll be reframing the Visa Inc deep dive to cover both investment cases.
This deep dive is one I’m taking very seriously and would likely be among the longest I’ve published, alongside the TSMC deep dive. The key reason for this is that understanding the intricacies of how Visa, Mastercard (and American Express) truly function could lead to even more investment opportunities for us in the broader payments space.
Premium readers will have access to valuation models of both Visa and Mastercard, and to give you an idea of what I’ll be covering in the deep dive, I’ve included the table of contents below.
