Tech company Apple has again rivaled competitor Microsoft as the American company with the highest stock market value.

Apple rose 2.7 percent, partly as a result of the partial trade agreement concluded by the United States and China. Both companies are worth more than 1 trillion dollars on the stock market.

With Apple's rise, that company is now worth $ 1067.5 billion. That is 1 billion dollars more than Microsoft.

Apple and Microsoft have been competing for the title of most expensive, listed company in the world for some time. Amazon also participated in that fight for a while, but the market value of the web store is currently just under $ 857 billion.

When Saudi Arabian state oil company Saudi Aramco goes public, it is over with the dominance of American tech companies. That company would be worth $ 2 trillion.
