Analysts said the latest unexpected salvos from the White House highlighted the uncertain path investors are having to walk owing to the President’s volatile policy pivots.

“The stock market seems to dance to Trump’s tune: first a threat, then a pullback, quickly followed by a rebound as speculative investors anticipate a concession from the US President,” said Jochen Stanzl, chief market analyst at CMC Markets trading platform.

“This morning’s confirmation of such expectations reinforces the so-called ‘Trump Pattern’, which is increasingly seen as a successful strategy for risk-tolerant investors.”

The dollar remained under pressure after dropping on Friday.

Traders are also looking to Wednesday’s release of minutes from the Fed’s earlier May policy meeting, hoping for an idea about the central bank’s views on the economy.
