Investors remain cautious on Monday following comments from Fed Chair Jerome Powell on Friday, with the Fed chief telling public radio's "Marketplace" show that U.S. economic growth remains positive while inflation continues to hold above the central bank's target.

"That means we don't need to be in a hurry to cut [interest rates]," Powell said. "The economy is strong right now, and the labor market is strong right now. And inflation has been coming down. We can and we will be careful about this decision because we can be."

On the Economic Front:

The U.S. manufacturing sector expanded for the first time in 17 months in March, according to the ISM monthly reading on the sector released Monday.

Beneath the headline, production saw the biggest gains, rising 6.2 points to 54.6, while prices increase to 55.8 and employment showed contraction at 47.4.

The tech giant said in a blogpost that existing customers can either continue their current licensing deal, renew, update, or switch to its new offerings starting April 1.
