American confidence in the U.S. economy hit an all-time high, shifting from negative to positive territory in the weeks following Donald Trump’s election on Nov. 8, 2016.

According to Gallup, “Americans expressed more positivity about the U.S. economy last week than they have at any other time during the nine years that Gallup has been tracking the U.S. Economic Confidence Index.”

Recorded in January 2015, the previous high of +5 inched up to +6 for the week ending Nov. 27, 2016.

“Americans’ confidence in the economy recently shifted from negative to positive territory after Donald Trump was elected president three weeks ago,” notes Gallup. “The index was -11 in the last full week before the Nov. 8 election, but then jumped to +4 the week after. Gallup noted that the change was largely attributable to Republicans becoming more optimistic about the economy's direction. Registering at +9 for Nov. 25-27, this three-day average bests the previous high of +7, which Gallup recorded after this November's election, as well as once before in January 2015.”

The Gallup tracking poll shows American confidence has markedly improved from its near continuous below zero level, hitting its lowest level of -65 in October 2008.

Gallup’s weekly scores were briefly positive several times during a three-month span between late 2014 and early 2015, “when U.S. consumers enjoyed a sustained drop in gasoline prices,” says Gallup.

Both the “current conditions index” and the “economic outlook component” of Gallup’s U.S. Economic Confidence Index are also seeing positive gains, with the “current conditions index” sitting at +8 and the “economic outlook component” sitting at +4.

30 percent of Americans rated the U.S. economy as “good” or “excellent,” while fewer (22%) said it was “poor,” resulting in the “current conditions index” score of +8 – “the highest score recorded for this component.”

Meanwhile, for the week ending Nov. 27, the “economic outlook component” pushed three points higher from +1 to +4, the result of 49 percent (49%) of Americans saying economic conditions in the U.S. are “getting better,” while only 45 percent (45%) say things are “getting worse.”

The Dow also indicated a marked increase of confidence in America’s economy, with U.S. markets skyrocketing and the Dow closing above 19,000 “for the first time in its 120-year history.”
