The world is closely observing the unfolding implications of the 2024 U.S. election, particularly as it influences financial markets and investment strategies. Recently, shares in billionaire investor Bill Ackman’s primary investment vehicle, Pershing Square Holdings, have suffered a significant decline, falling approximately 15% this year. This downturn is largely attributed to the adverse effects of former President Donald Trump’s aggressive trade policies, which have adversely impacted one of Wall Street's most vocal supporters of the Trump administration.

In a troubling turn of events for Ackman, whose London-listed investment trust has seen its stock price drop by more than 3% in a single day, there are growing concerns regarding the volatility of the financial markets. As he expressed on social media platform X, he fears that if the U.S. were to escalate economic tensions globally, it could lead to a severe contraction in business investment, consumer spending, and an irrevocably damaged international reputation that may take decades to repair.

Less than 100 days into what would be Trump’s second term, the reverberations of the financial markets’ instability have left many of Ackman’s significant investments in jeopardy, resulting in considerable losses for his investment trust. Notably, high-profile stocks such as Nike, Chipotle—a popular Mexican-style fast-food chain—asset management firm Brookfield, and tech giant Alphabet have all plummeted by over 20% since the beginning of the year. These losses have compounded Ackman’s challenges, particularly as these stocks constituted a large portion of his portfolio at the end of the previous year, valued at nearly $2 billion for Alphabet and $1.8 billion for Brookfield, as reported in the firm’s annual disclosure.

To visualize the impact, it’s worth noting that the Brookfield Place shopping center in New York stands as a testament to the real estate and asset management sectors that Ackman has heavily invested in, which have all seen significant declines amidst the current economic turbulence.

As of last Monday, Pershing Square Holdings reported a 1.2% decline in its net asset value for the year, based on the firm’s latest public disclosures. Additionally, it was revealed that the trust had not engaged in any hedging strategies prior to the recent market downturn, which might have mitigated some of the exposure to losses.

However, Ackman is not alone in his financial struggles, as other prominent Wall Street figures are also feeling the pinch from Trump's controversial trade policies. Fellow billionaire hedge fund manager Dan Loeb, who has also criticized the tariffs, has witnessed a nearly 10% drop in shares of his publicly traded fund, Third Point, since the year's onset. The fund's net asset value was reported down 1.4% as of last Wednesday, right before the U.S. equities market experienced a sharp decline due to the so-called “liberation day” tariff announcements made by Trump.

In a bid to address these mounting concerns, Ackman took to social media, urging the president to consider a 90-day “timeout” for negotiations over what he referred to as “unfair asymmetric tariff deals.” He expressed his belief that a pause could pave the way for more equitable agreements that would benefit the economy.

On the same day, Ackman directed criticism towards U.S. Commerce Secretary Howard Lutnick, who publicly voiced his support for the tariffs. Ackman alleged that Lutnick and his company, Cantor Fitzgerald, stood to benefit from the economic fallout resulting from such policies. However, he later moderated his remarks, acknowledging that it was unfair to criticize Lutnick and expressing confidence that Lutnick was doing his best for the country. Nevertheless, Ackman suggested that Trump’s reliance on flawed economic advice from his team could be detrimental.

Interestingly, Ackman’s investment strategy is not entirely characterized by losses. His stakes in government-sponsored mortgage entities, Fannie Mae and Freddie Mac, have thrived, with increases of 60% and 32%, respectively. Ackman anticipates that the Trump administration may move to privatize these organizations, significantly boosting their market value.

As the situation evolves and the 2024 election approaches, the financial community will be watching closely to see how investors like Ackman navigate the turbulent waters of American politics and economic policy. Pershing Square has opted not to comment further on these developments, leaving many to speculate about the future of both Ackman’s investments and the broader implications of Trump’s policies on Wall Street.
