The index futures and ETFs are up somewhat today so far.
Trade deal between US and UK ... I do not expect a fantastically satisfying deal. I read where the 10% will stay in place. As well, trade with the UK is relatively small. Will it be a template for other deals? LOL Who knows? And any deal can be torn up anyway. NAFTA as an example. And the USMCA could be next.
If it gets back close to what was there before, the market will see that as a positive.
The economy? That is another matter.
IMO.
