Our investment campaign in Advanced Micro Devices (AMD) began in the second half of 2018, and we have seen a new management team reinvigorate the company’s product portfolio of microprocessors for PCs and servers, graphics processors, and video game consoles. These new, higher-margin products have helped the company partially close its margin gap with peers and capture share from market leader Intel. While we believe there is meaningful runway for further share gains and margin expansion, AMD has appreciated far beyond our mid-cap market cap mandate, and we exited our position.”

We previously owned NVIDIA and sold it in the third quarter of 2020 as the price to value gap closed and our margin of safety was reduced. As with all our MVP companies, we continued to follow NVIDIA closely. Since that time, NVIDIA reported excellent results and its value has compounded rapidly. The technology selloff at the beginning of the year negatively affected the stock price while our estimate of NVIDIA’s value per share increased. This happy combination of events created a margin of safety and an opportunity to once again add NVIDIA to the portfolio.”

“We concluded our campaigns in Zoom Video Communications. We have been paring our position in Zoom for several quarters, anticipating the reduced need for video conferencing as vaccination rates climb and people return to their workplaces. That said, we believe there is a strong case to be made that the pandemic has prompted a permanent inflection in videoconferencing’s importance—sustainably higher remote work arrangements, more online learning and less business travel. Furthermore, the company’s dramatically expanded user base (up 485% YoY in Q3) positions it well to cross sell additional services, Zoom Phone in particular.

In its Q3 2021 investor letter, LRT Capital Management highlighted a few stocks and Novo Nordisk A/S (NYSE:NVO) was one of them. Here is what the fund said:
“Novo Nordisk is the global leader in insulin, which is, sadly, a growing business as more and more people around the world suffer from diabetes. millions of people need daily injections of insulin to stay alive54, a number that, unfortunately, is likely to continue to grow by millions more in the coming decade. It may seem at first glance that insulin should be a commoditized business, after all, it was discovered and synthesized over a hundred years ago, but nothing could be further from the truth. There are many types of insulin and Novo Nordisk has spent billions on R&D over the years to develop new products. On February 11th, the company reported favorable results from a phase-3 trial of Semaglutide, a drug that is currently used for Type 2 diabetes treatment. The study evaluated the use of Semaglutide for weight loss treatment in non-diabetic patients and found a significant impact on weight loss for patients receiving Semaglutide vs. the placebo control group. If Semaglutide is approved for weight loss treatment, we expect it will be meaningfully accretive to the company’s bottom line.
The company’s proprietary product line supports returns on invested capital of over 40%, and while sales growth is relatively slow (+6% annualized CAGR over the past decade), the company’s shares trade at a reasonable valuation of only 22x forward earnings. For a company with an extremely predictable business, high returns on capital, and an easily forecastable future, we believe this to be highly attractive.”
