JPMorgan study: Trump shock posts from social media decrease

On February 18th, according to JPMorgan research, the number of market-impacting posts from social media since Trump returned to office has decreased significantly. Compared with his first term, only 10% of Trump's 126 posts on sensitive topics such as trade tariffs, foreign relations and the economy caused significant currency market volatility, although this proportion is increasing.
The report noted that Mr. Trump had recently posted more than 20 related posts, although double the January average, but well below the peak of 60 per week in the 2018-2019 trade war. JPMorgan said posts about tariffs had the biggest impact on the market, with nearly a third triggering volatility.
Among them, in early February, Trump posted that he had used emergency powers to impose 25% tariffs on Mexico and Canada, although he delayed the measure two days later, causing the Mexican peso and the Canadian dollar to fall by more than 2% and 1% respectively.
Analysts at JPMorgan said trading on Mr. Trump's tweets was not highly profitable, with a backtest showing that earnings were expected to be no more than 4 per cent even in a "very optimistic" scenario.
