Traders work on the floor of the New York Stock Exchange on March 5, 2025.

Trump made 327 stock purchases on April 8, 2025, according to a CNBC analysis of the president's annual financial disclosure for 2025 that includes trades, income and liabilities and was released on Tuesday. That made April 8 his 11th busiest day for stock buying last year, more than five times the daily average of roughly 62 for the calendar year, according to the CNBC analysis.

While investors and businesses spent the early days of April 2025 fretting over the future of global trade and the economy, President Donald Trump was busy buying into the stock market sell-off he created.

His flurry of buying came on the tail end of a steep four-day spiral that was sparked by the unveiling of his plan for broad and high tariffs. CNBC's analysis shows Trump's purchasing focused on the megacap technology stocks that were hard hit after he released the policy on April 2, which he dubbed "liberation day."

The episode captures a central theme running through Trump's second term: A president with vast power to move markets is also a president with a vast personal stake in them — with more personal investment at stake than any of his predecessors.

On April 8, the broad S&P 500 index finished that session below the 5,000 mark and within inches of the threshold for a bear market, a term used to describe a 20% drawdown from a recent high. Over the four-day run alone, the closely followed stock market benchmark tumbled more than 12%.

The next morning, minutes after the opening bell on April 9, Trump helped the market abruptly turn around.

Trump posted on Truth Social, the social media platform he owns, that "THIS IS A GREAT TIME TO BUY!!!". Later that day, Trump announced he was walking back some of the market-roiling tariffs he had announced a week prior.

The S&P 500 climbed around 9.5% in that session, marking one of its best days on record. The benchmark has cumulatively surged around 50% since April 8, 2025.

The White House, when asked to comment on the timing of Trump's April 8, 2025 trades, spoke more generally about the president's assets.

"As President Trump said, he has a lot of assets because he was a massively successful businessman prior to becoming President, which was why he was elected to office in the first place," White House spokesperson Anna Kelly told CNBC. "All of the President's assets are in held in fully discretionary accounts managed by independent third-party financial institutions. There are no conflicts of interest."

Trump on Wednesday told reporters his trades are managed by outside parties.

"I don't get involved in my personal — we have funds that run my money," Trump told reporters.
