LONDON Britain’s benchmark equity index will not make much, if any, progress for the rest of 2016, due to uncertainty over the country’s vote on European Union membership and fears of a global slowdown, a Reuters poll found.

The poll of 27 traders, fund managers and strategists, taken in the past week, gave a median forecast for the FTSE to end 2016 at 6,350 points. It was forecast down at 6,000 points by the middle of 2016.

This would represent the FTSE making minor gains of some 3 percent from Thursday’s close of 6,174.9 by year end.

Among leading investment banks, Citigroup and UBS forecast the FTSE ending the year at 6,600 and 6,500 points respectively, but JP Morgan was more bearish with a 5,950 point forecast.

The FTSE 100 hit a record high of 7,122.74 points in April 2015 but has since lost ground, partly due to concerns about a China-led global economic slowdown, something which could weigh on stocks this year too.

Britain’s June 23 vote on whether to leave the European Union – dubbed “Brexit” – has added a further element of uncertainty.

“Markets in general don’t like uncertainty and the indecision that would arise following the UK leaving the EU is highly unlikely to be supportive of indices,” XTB UK analyst David Cheetham said.

Opinion polls have been close but the “In” campaign has mostly been showing a slight lead.

Traders said any Brexit worries would weigh more on the FTSE 250 mid-cap index .FTMC than the FTSE 100, since a drop in sterling could benefit the internationally-focused exporters that tend to be in the FTSE 100 rather than the FTSE 250.

“We are working on a 35 percent chance of Brexit. If the UK remains, there is likely to be an equity rally, if the UK leaves the stock markets will be subdued while uncertainty remains as the UK negotiates deals with Europe,” Horizon Stockbroking director Kyri Kangellaris said.

Traders and fund managers also said underlying, persistent worries about a China-led global economic slowdown could hinder the FTSE’s progress.

The FTSE is particularly sensitive to the China worries, which have hit commodity prices due to the country’s role as a leading consumer of metals and oil. The shares of oil companies and mining companies account for around 20 percent of the FTSE’s overall market capitalisation.

“Those looking for equity outperformance should look to southern Europe,” Jonathan Roy, partner at Charles Hanover Investments, said, adding that markets in Italy and Spain could rise more on the back of economic stimulus measures from the European Central Bank.
