LONDON (Reuters) - European shares pulled back on Wednesday from 21-month highs hit after strong earnings while the dollar fell on concerns that U.S. President Donald Trump's dismissal of his FBI chief could make passage of his tax reform plans more difficult.
Expectation-beating first-quarter company results have lifted stock markets across the globe, with European full-year earnings forecasts set to be their best since 2010. The prospect of U.S. tax cuts has also helped push shares higher.
At the same time, measures of market volatility are at rock-bottom. The U.S. VIX index fell on Tuesday to 9.56, its lowest since late 2006. [https://bsmedia.business-standard.comreut.rs/2pja9xd]
However, Trump's abrupt sacking of FBI Director James Comey marked a fresh intrusion of politics into markets after Emmanuel Macron's weekend victory in the French presidential election had seemed to clear the decks of major political risk, at least in Europe.
"There is no doubt that Trump is dominating proceedings this morning after the sacking of Comey. This is a political story rather than a market story, but yet again it creates uncertainty in the market, which leaves everything the president does with a cloud floating over it," said James Hughes, chief markets analyst at GKFX in London.
