Trump bought AAPL, NVDA as markets tumbled April 8; tariff reversal next day lifted S&P 9.5%

President Trump made 327 stock purchases on April 8, 2025—his 11th busiest trading day—as the S&P 500 plummeted following his April 2 announcement of sweeping tariffs (dubbed "liberation day"). Trump's buying spree focused on megacap tech: Apple, Alphabet, Amazon, Microsoft, and Nvidia, each receiving $100,001–$250,000 purchases. All five stocks are in the Magnificent Seven and had been hammered by tariff fears; the S&P 500 had fallen over 12% in the four-day spiral and sat near the edge of a bear-market definition (20% drawdown).

The next morning, April 9, Trump posted on Truth Social: "THIS IS A GREAT TIME TO BUY!!!" and announced a partial retreat from the tariff plan. The S&P 500 jumped 9.5% that session—one of its best days on record. Apple surged 15% (its best day since 1998), and Nvidia leaped 19%. The index has cumulatively surged roughly 50% since April 8. Trump's personal financial disclosure, released this week, showed $2.24 billion in 2025 revenue from crypto, golf properties, legal settlements, and merchandise.

For market observers and architects watching policy execution risk, the timing underscores how presidential leverage over markets compounds personal investment exposure. The trades also exemplify how tariff policy—which directly impacts GPU/chip sourcing costs and infrastructure spend—remains a key variable in AI capex forecasts, particularly for companies (Nvidia, ASML, etc.) that depend on cross-border semiconductor and photolithography-tool supply chains.
