There’s no doubt that President Donald Trump loves watching the stock market go up.
However, according to new research from Bank of America Merrill Lynch, the stock market hates when Trump tweets.
The investment bank analyzed the S&P 500’s daily movements on days when Trump was relatively quiet (publishing five or fewer tweets) compared to days when he was exceptionally prolific (unleashing more than 35 tweets).
The analysis found a massive gap in the S&P 500’s daily performance based on those metrics. When Trump types too much, the stock market bellwether index tends to fall to the tune of 9 basis points. On saner days when he is more engaged in his presidential duties, the index climbs an average of 5 basis points.
That’s a 0.14% swing.
Of course, correlation does not equal causation, but Trump’s Twitter habits might be another variable that investors should monitor more closely.
The problem is that there’s no way to predict to what extent Donald Trump is going to use Twitter on a particular day.
But a closer look at recent trends suggests that he has been getting more active.
President Trump’s activity on Twitter has picked up the pace in recent days, according to data from Trackalytics.
From the chart above, it can be clearly deduced that Trump’s tweeting stepped on the gas toward the end of June.
He started sending upwards of 30 tweets on a more frequent basis every week, and by the end of July, the S&P 500 had started going south.
So the next time you want to time the stock market, don’t forget to check your Trump tweet counter.
