The unemployment rate continues to fall. The U.S. economy keeps adding jobs at a healthy clip. What could surprise investors about the monthly jobs report to be issued on Friday?

There is always President Trump’s Twitter feed.

A month ago, Trump broke with decades of presidential protocol by commenting on the social media network that he was “looking forward to seeing the unemployment numbers.”

The remark, posted about an hour before the report on May hiring was released, did not indicate what the data would show, but Trump’s decision to draw attention to the report was noticed by the community of traders who obsess over that data. Traders in the bond and currency markets were particularly quick to react.

When the report was released at 8:30 a.m., it showed that the U.S. economy had added a better-than-expected 223,000 jobs in May and that the unemployment rate had dipped to its lowest level in 18 years.

Anyone who read the tea leaves via Trump’s Twitter feed might have been rewarded for placing the early trades. Bond yields, which rose after the 7:21 a.m. tweet, moved even higher after the report, for example.

The White House later confirmed that Trump had been briefed on the numbers the night before, as is typical.

To be clear: There is nothing unlawful with basing trades on Trump’s Twitter feed, and it is not clear if a 1985 rule that prohibits “employees of the executive branch” from commenting on the data until an hour after it is released applies to the president.

But it does mean that traders will get to wonder whether an early Twitter post will become a new element in the monthly jobs-day ritual. On a holiday-shortened week in the United States, the anticipation of a presidential tweet has become an “interesting sidelight” that people have an eye on, said J.J. Kinahan, chief market strategist at TD Ameritrade.

“There was a movement in the market, there’s no question about that,” he said of the reaction last month, adding: “You have to see if it happens again before you say it’s something you have to pay attention to.”
