Trade Tariffs Increase Instability And Lower The Market Value Of Tech Giants Since Trump Took Office, Study Says
Since Donald Trump’s inauguration on January 20, the value of the market of companies listed on American stock exchanges has fallen by US$ 9.81 trillion, according to a survey by the consultancy Elos Ayta. This decline is associated with recent economic measures, such as the imposition of tariffs on imports, which increased uncertainty in the financial market, according to the Metropoles website.
Two Days of Trump, US$ 6 Trillion Lost
On the trading days of April 3 and 4, losses reached US$ 6.08 trillion, primarily affecting the technology sector. The so-called “magnificent seven” — a group that includes companies like Nvidia, Apple, and Microsoft — led the decline.
Major Losses:
- Nvidia: US$ 183 billion on April 4; cumulative loss of US$ 1.07 trillion
- Apple: US$ 533 billion since the beginning of 2024
- Microsoft: US$ 515 billion year-to-date
Widespread Impact Beyond The Tech Sector
Companies in other sectors also faced sharp devaluations:
-
On the coast of Guyana, neighboring Brazil, ExxonMobil has begun drilling oil wells with an automated system that practically removes human hands from controlling the drill.
-
Brazilians create cashierless mini-market in the USA, use AI to define products and prices, raise R$ 10 million, and achieve financial balance in the first month before planning nine more units in Miami by the end of 2026.
-
BNDES opens billion-dollar credit of up to R$ 50 million per client for the purchase of trucks, buses, and equipment and promises to accelerate the renewal of the heavy fleet on Brazilian roads.
-
PCC and Comando Vermelho enter the U.S. terrorism list and the Brazilian market is already trying to understand where this might hit first.
- ❌ Losses on April 4 (non-tech): US$ 2.37 trillion
- ❌ Cumulative losses since January (non-tech): US$ 5.54 trillion
Trade Policy As A Risk Factor
Experts point out that the adoption of new import tariffs contributed to the instability scenario, raising concerns over a possible trade war.
“The market reacted brutally,” said Einar Rivero, partner at Elos Ayta. “Investors are suspicious of the impact of the new trade policies.”
With trillions evaporating in market value, the start of Trump’s new term has generated strong volatility in the markets — with effects that may extend beyond the United States.
