U.S. stocks popped up last week after a trade truce between the U.S. and China, and they jointly agreed to cut tariffs of 90 days. Technology stocks soared, with Tesla and NVIDIA leading the way. However, due to the lack of new developments in tariffs, it is not clear whether this buoyancy sentiment can continue.

First, Moody's rating lowered the U.S. credit rating to the second highest. This means investors can demand higher returns from the U.S. Treasury under ostensibly reduced trustworthiness. Rising output from the treasury may in turn put pressure on stocks. While Moody's is just joining the latest from S&P and Fitch ratings, lowering the U.S. from the highest ratings, which did so in 2011 and 2023, it could create another crack through the already fragile stock market.

Although NVIDIA was one of the winners of last week's rally, it is still fighting for restrictions on chip exports on China and has reviewed its business activities. This is important, as NVIDIA CEO Jensen Huang said China's artificial intelligence division "does not lag behind the United States" and could reach $50 billion in three years. He added that losing in this market would be a "huge loss".

So, whether last week's rally can be relied on, then, headlines from the White House this week will be coming from.
