(New York) The results of Nvidia which exploded expectations were not enough to keep the markets in the green Thursday, the hour being with caution before words of central bankers.

The American processor giant had set the bar high for its second quarter financial results, but far exceeded it with net profit multiplied by almost 10 over one year, to 6.2 billion.

After gaining more than 6% in early trading and approaching $500, Nvidia stock ended flat (0.10% at $471.63). But its value has multiplied by almost 3.25 since the beginning of the year.

“We thought that with the results, the best of the whole season, the market was going to take off, as in previous results, but we can see that it’s winded”, observes Frédérik Rozier, portfolio manager at Mirabaud.
