Nvidia makes history with $4 trillion market cap while markets brush off tariff worries

• Traders seem untroubled by the possibility that tariffs’ return to the spotlight could lead to another market crash. As stocks rose, Nvidia became the first company ever to reach a market cap of $4 trillion. 

Stocks rose on Wednesday after two days of declines. Those downturns proved to be little more than blips in the continuous—albeit choppy—march the stock market has had since its recent nadirs in April. Meanwhile, tech juggernaut Nvidia hit a historic new $4 trillion milestone.
