Top 10 Stocks to Buy According to Two Sigma Investments
10. Tesla, Inc. (NASDAQ:TSLA)
Number of Hedge Fund Holders as of Q4: 126
Two Sigma Investments’ Equity Stake: $517.36 Million
Known as an American multinational automotive and clean energy company, Tesla, Inc. (NASDAQ:TSLA) is headquartered in Austin, Texas. The stock has dropped over 40% since January’s peak, wiping out the previous gains it experienced after the US Election Day. The decline is largely driven by falling sales worldwide and a lack of effective action from its CEO to address the downturn.
The company is facing a major crisis, having reported its first-ever global sales decline last year, with this year showing no significant improvement. Tesla, Inc. (NASDAQ:TSLA) is particularly struggling in China, where competition from domestic manufacturers has intensified. In the past month, Tesla’s shipments in China dropped 49% year-over-year, while sales in Europe have also slumped. Germany saw an especially steep decline, with Tesla sales plummeting 76% last month, partially due to backlash over Elon Musk’s political affiliations.
The situation worsened with bad news from China, where rival automaker BYD unveiled a charging system that outperforms Tesla’s, providing 250 miles of range in just five minutes. Tesla, Inc. (NASDAQ:TSLA) also responded to its declining market share in China by offering a free monthlong trial of its Full Self-Driving software, which analysts view as a desperate move.
Following these developments, Tesla, Inc. (NASDAQ:TSLA) stock fell 5% in the U.S. on March 17 and another 5% on March 18. While the company remains the leading EV brand in the U.S., increasing competition and concerns over Musk’s political stance are damaging its brand value. JPMorgan analysts recently noted that Tesla’s rapid decline in brand perception is nearly unprecedented in the automotive industry. Meanwhile, a growing movement known as “Tesla Takedown” is gaining traction on social media, urging consumers to boycott the brand, sell their Tesla vehicles, and protest at Tesla showrooms.
Tesla, Inc. (NASDAQ:TSLA)’s Q4 2024 earnings report seemed to have predicted these challenges, with revenue increasing 2.15% year-over-year to $25.71 billion, but operating profit falling 23.3% to $1.58 billion. Earnings per share dropped 4.8% below analyst expectations, underscoring financial difficulties amid heightened competition and production setbacks.
Despite these struggles, Tesla, Inc. (NASDAQ:TSLA) remains a dominant force in the EV industry, with cutting-edge technology, strong brand recognition, and continued innovation in autonomous driving. The company’s leadership in the U.S. market, coupled with its ability to rapidly adapt, suggests that Tesla could still be a top stock to buy as a long-term investment for those willing to weather short-term volatility.
Polen Focus Growth Strategy stated the following regarding Tesla, Inc. (NASDAQ:TSLA) in its Q4 2024 investor letter:
“The largest relative detractors in the quarter were Tesla, Inc. (NASDAQ:TSLA) (not owned), Thermo Fisher Scientific, and Broadcom (not owned). We’ve spoken at length about our rationale for not owning Tesla. The stock enjoyed a 54% return during the quarter, with effectively all of the share price performance strength coming in the post-election period, as the market expressed a positive view on Elon Musk’s prominent role in the incoming Trump administration and its potential implications for Tesla. While we agree this development should be a net positive for Tesla and recognize the company’s interesting future prospects for autonomous driving and humanoid robots, its current valuation demands that shareholders pay primarily for potential innovations that have yet to materialize, with uncertain risks and timelines, presenting a different type of risk profile than we are comfortable with. Today, Tesla is an automobile manufacturer limited to the higher-income segment and is increasingly challenged to sell vehicles when interest rates are not zero. As such, we continue to question the company’s long-term growth profile, its ability to scale a large robotaxi service (which seems to be the source of euphoria in Tesla shares), and its corporate governance.”
9. Mastercard Incorporated (NYSE:MA)
Number of Hedge Fund Holders as of Q4: 151
Two Sigma Investments’ Equity Stake: $567.64 Million
Mastercard Incorporated (NYSE:MA), established in 1966, is a global financial services corporation specializing in the processing of financial transactions. Headquartered in Purchase, New York, the company provides a comprehensive suite of payment solutions and related services.
On January 20, Mastercard Incorporated (NYSE:MA) announced its financial results for the fourth quarter and full year of 2024, showcasing strong business performance. With a market capitalization of $504 billion, for the fourth quarter, the company reported a net income of $3.3 billion, with diluted earnings per share (EPS) of $3.64. Adjusted net income stood at $3.5 billion, with an adjusted diluted EPS of $3.82. The company’s net revenue for the quarter totaled $7.5 billion, marking a 14% year-over-year increase, or 16% when adjusted for currency fluctuations.
CEO Michael Miebach highlighted the resilience of consumer spending, stating, “Affluent consumers have benefited from the wealth effect, while the mass segment remains supported by the labor market.” Mastercard’s cross-border volume, which measures transactions made outside the country of card issuance, surged by 20% during the quarter. Chief Financial Officer Sachin Mehra attributed this increase to early travel spending and heightened cryptocurrency-related transactions. According to analysts, while a seasonal increase in transaction volumes was expected due to strong holiday spending, the surge in cross-border transactions was an unexpected positive development.
Throughout the fourth quarter of 2024, Mastercard Incorporated (NYSE:MA) repurchased 6.5 million shares for $3.4 billion and distributed $606 million in dividends. Over the full year of 2024, the company repurchased 23 million shares for $11 billion while paying out $2.4 billion in dividends.
Mastercard’s strong revenue growth, expanding cross-border transaction volume, and consistent share repurchase program demonstrate its financial strength and investor-friendly approach. With its diversified payment solutions and a solid strategy for long-term expansion, Mastercard Incorporated (NYSE:MA) remains a compelling investment opportunity.
Conventum – Alluvium Global Fund stated the following regarding Mastercard Incorporated (NYSE:MA) in its Q4 2024 investor letter:
“Last quarter we wrote about the credit card companies and the Fund’s latest investment, Visa (up 15.2%). With its strong share price performance, that position had grown to be greater than 5%. As we had discussed here, we consider there to be negligible differences in investment merits when compared to Mastercard Incorporated (NYSE:MA) (up 6.8%). Whilst Visa appears a little cheaper on traditional price metrics, our view is that Mastercard has marginally higher growth prospects. Irrespective, both are deserving positions in the portfolio, and given their similarities, and the 5/10/40 rule, in order for us to maintain maximum portfolio flexibility it made sense to sell a little Visa and buy a little Mastercard, and their combined position is 6.2%.”
