The Dow Jones rose 1.05%, the Nasdaq index 0.73% and the broader S&P 500 index 0.76%.

For Patrick O'Hare, the session played out when the S&P 500 briefly dipped below a major technical level (the average of the last 200 trading days) before recovering, then gaining momentum before the close.

“The market was ripe for a rebound after falling in February and the first day of March,” the analyst explained.

Stocks "had fallen too much, too fast, and traders were waiting for an excuse to start buying again."

“The message that the technology sector sends is that of efficiency, reduction in the workforce and the preservation of growth in profits,” she argues.

The momentum from the technical rebound allowed the New York market to overcome an early session in the red for the Nasdaq and the S&P 500.

The gloomy tone of the first exchanges had thus been given by the drop in weekly jobless claims, to 190,000 against 192,000 the previous week and 197,000 expected, a new illustration of the resistance of the job market.

Another downside is the 3.2% jump in the average cost of labor in the fourth quarter of 2022, according to data released Thursday by the US Department of Labor, when economists predicted 1.4%.

These two indicators had caused bond yields to boil a little more.

The yield on 10-year US government bonds stood at 4.06%, against 3.99% the day before closing.

The market "will continue to be volatile and to dissect down to the smallest economic data", announces Nancy Tengler.
