DETROIT — General Motors strengthened its pretax profit estimate for 2018 and predicted even stronger performance for this year as its executives made a presentation to investors on Friday.

Shares jumped nearly 9 percent in midday trading.

CEO Mary Barra also said the company doesn’t foresee any further job cuts through 2020. Last year GM announced plans to close five North American factories and lay off 14,000 workers.

The company predicts 2018 pretax, per-share profits will be higher than the $5.80 to $6.20 range it forecast in the third quarter. For 2019, it expects that to increase to $6.50 to $7.

The rosy profit forecast comes despite declining sales in the U.S. and slowing sales in China. GM also plans to exit several car lines in the U.S. in the coming year.

The outlook exceeded Wall Street’s expectations for both years. Analysts polled by FactSet expect pretax earnings of $6.24 for 2018, and they predict a decline for this year, to $5.92.

In a briefing for reporters before the presentation in New York, Barra said GM has enough new trucks and SUVs coming to offset any U.S. sales decline caused by scrapping car models like the Chevrolet Cruze.

The company is rolling out new full-size pickup trucks and has heavy-duty versions coming later in the year. It also will have a year of sales for the Cadillac XT4 and Chevrolet Blazer new SUVs, as well as new Cadillacs to be announced.
