NEW YORK, April 9 (Reuters) - Billionaire investor Bill

Ackman's Pershing Square Holdings portfolio has lost nearly 14%

so far this year, the firm told investors on Wednesday.

The losses, through April 8, do not include gains seen on

Wednesday, when markets surged after U.S. President Donald Trump

paused most tariffs for 90 days.

The losses, primarily incurred over the previous week,

reflect sharp global declines as investors reacted to the Trump

administration's plans to impose heavy tariffs on nearly all

trading partners.

In the first quarter, Pershing Square Holdings slipped just

1.2%.

Ackman invests in a select group of U.S. stocks, including

Nike ( NKE ) and Chipotle Mexican Grill ( CMG ), both of which

have suffered losses since January but saw double-digit gains on

Wednesday.

His portfolio is closely watched in the industry for

investment trends.

Long known as one of Wall Street's most outspoken investors,

Ackman took to X this week to express his dismay about the

proposed tariffs, warning they could push the economy into

recession.

He suggested holding tariffs at 10% across the board,

keeping pressure on China, while pausing reciprocal tariff

implementation for 90 days.

Trump on Wednesday paused the tariffs, and the S&P 500 index

jumped more than 9%.

Ackman has delivered some of the hedge fund industry's

strongest returns, including a remarkable 70.2% gain in 2020,

the year the COVID-19 pandemic struck.
