The election of Donald Trump has brought with it a surge in optimism in the United States over the economy and stocks not seen in years.
The CNBC All-America Economic Survey for the fourth quarter found that the percentage of Americans who believe the economy will get better in the next year jumped an unprecedented 17 points to 42 percent, compared with before the election. It's the highest level since President Barack Obama was first elected in 2008.
The surge was powered by Republicans and independents reversing their outlooks. Republicans swung from deeply pessimistic, with just 15 percent saying the economy would improve in the next year, to strongly optimistic, with 74 percent believing in an economic upswing. Optimism among independents doubled but it fell by more than half for Democrats. Just 16 percent think the economy will improve.
