Wall Street on Thursday rose after President Donald Trump exhorted traders to "go out and buy stock now" following the announcement of a trade deal between the U.S. and the United Kingdom - the first of its kind since Trump's imposition of sweeping reciprocal tariffs in April.

Shares of Rigetti Computing ( RGTI 12.11%) are skyrocketing on Thursday. The quantum computing start-up's stock surged 10.5% as of 2:50 p.m. ET and was up as much as 12.3% earlier in the day. The rise comes as the S&P 500 gained 1.3% and the Nasdaq Composite rose 1.8%.

According to reports, the deal will focus on steel and automobiles, whose imports Trump has hit with a 25% tariff.
