“Moody’s: Revenue, operating profit margins, and EPS all exceeded expectations, and annual guidance for these items (and for free cash flow) was raised. In MIS (Moody’s Investors Service) which houses the traditional ratings business, the outlook for debt issuance was raised for the remainder of the year, while MA (Moody’s Analytics) also came in ahead of expectations. The company leveraged strong revenue growth with strong operating profit margin improvement of 200 bps, with EPS coming in $0.22 ahead of consensus estimates. Management alluded to having interesting opportunities in their M&A pipeline, which we will have to assess when the time comes, but Moody’s management team has been very effective at allocating capital in the past toward value-creating bolt-on acquisitions, especially in their Moody’s Analytics business, a key growth driver for the company.”

“Alibaba also detracted from performance as the company continues to remain under regulatory scrutiny from both the Chinese State Administration for Market Regulation on antitrust concerns and the U.S. Securities and Exchange Commission on ADR listing requirements. Despite the regulatory overhang, we believe that Alibaba’s competitive positioning and growth outlook remains intact, even if the company must pay fines or modify some business practices. We viewed the current valuation at <20x next twelve month’s earnings as a compelling opportunity to add to our position. Alibaba is the second largest position in the Portfolio.”

“Ferrari: After posting standout performance in 2020, beating the S&P 500 by over 20%, Ferrari’s share price performance has lagged for much of this year. The main issue this quarter was the company pushing out their medium-term financial targets due to development and production delays caused by COVID, but this only led to a 1% decline in the stock price for the full quarter. While we believe the company did a fantastic job maintaining production in light of COVID, it did not surprise us that some of their longer-term, new model introductions might be delayed by a couple of quarters. While disappointing of course, Ferrari is curating a set of extremely exclusive mechanical works of art and we are much happier seeing them take the time to do things right, rather than rushing to meet a self-imposed financial target.”
5. Micron Technology, Inc. (NASDAQ:MU)
Spier’s Stake Value: $16,996,000
Percentage of Guy Spier’s 13F Portfolio: 7.97%

In its first-quarter 2021 investor letter, Bonsai Partners mentioned Micron Technology, Inc. (NASDAQ:MU). Here is what the fund said:
“Micron is a manufacturer of memory semiconductor chips. Micron appreciated 17.3% during the quarter.
With the semiconductor cycle in full swing, sentiment continued to improve for major DRAM and NAND suppliers. Spot pricing for DRAM continues its upward march due to supply shocks across the industry and sustained demand levels that continue to outstrip supply.
As a result, Micron showed improving results for the fiscal first quarter, raised guidance intra-quarter for the fiscal second quarter, and offered strong guidance for the fiscal third quarter in both growth and margins.
While the cyclical nature of DRAM hasn’t changed, the cycles themselves continue to become more benign, leading to long-term economic improvement across these businesses. Micron is now continuously profitable, with industry players in a dramatically stronger position than even just five years ago.
The biggest negative surprise in the quarter came from Micron’s exit from its 3D XPoint hybrid memory business. The company also announced its decision to sell its accompanying Utah fab. Fortunately, this development does not alter the investment thesis much since 3D XPoint was an option ticket for future growth. While it’s unfortunate this product didn’t pan out, now is an excellent time to sell a fab, so perhaps it is a blessing in disguise?”
4. Mastercard Incorporated (NYSE:MA)

“Mastercard: Q2 revenue and EPS beat consensus estimates by 3.7% and 12% respectively. Operating margins also beat consensus by +240 bps. Gross domestic volume growth of +38.3% (+32.8% in constant currency) was buttressed by continued e-commerce strength and better in-store performance, while purchase volumes grew 41.8% (35.5% in constant currency). Cross border performance was strong, but durability remains uncertain given uncertainty arising from the Delta variant and its impact on travel and tourism. We believe Mastercard has a robust runway for growth given further travel recovery, new/existing partnerships, traction in digital payments, and ongoing economic recovery.”

“Higher long-term interest rates supported financials such as Bank of America, which has shown both defensive and offensive characteristics in the past year. We believe it continues to be the least risky large bank from a credit standpoint, with conservative underwriting and controlled risk taking, a leading consumer deposit franchise, scale and technology. It is also a leader in its commitments to sustainability, or as it terms it, responsible growth. Disclosure and reporting at all levels form a large part of this commitment, including gender diversity and equality, environmental commitments and support of communities in which it operates. In the first quarter Bank of America announced it is setting a goal of net-zero greenhouse gas (GHG) emissions in its supply chain and operations, and notably also in its financing activities, before 2050.”

“In financials, American Express has done an excellent job demonstrating the resiliency of its franchise in the midst of a global pandemic that drove a 60% decline in its core travel and entertainment business. The company’s spend-centric model has been helped by fiscal stimulus ensuring a flush consumer, while management continues to execute well by adding millions of new consumer and small and medium business accounts, which should benefit the franchise over the medium to long term. We remain optimistic regarding the company’s prospects as travel and entertainment activity rebounds, adding to our position in the quarter.”
