US stocks slipped by the close on Wednesday, as two opinion polls gave the Leave camp a slight lead ahead of the UK referendum on European Union relations taking place on Thursday, while oil prices sagged.
The market bellwether S&P 500 index closed down 0.2% at 2,085 and the Vix index, a measure of implied S&P 500 volatility over the next month, soared by more than 14% to 21.17. That’s above its long-term average of 20.0.
The S&P Midcap 400 shed 0.2% as well, taking it down to 1,491, while the S&P Smallcap 600 lost 0.5% to 705.
The wider small-cap ticker Russell 2000 was down 0.4% at 1,148.
Contributing to the downside, the US oil benchmark, the West Texas Intermediate, lost 1.1% to $48.85 despite weekly oil inventories suggesting a fifth successive week of stockpile contraction.
Midsession
US stocks were flat-to-lower at midsession on Wednesday after oil prices sagged and jitters grew over what a Brexit by the UK might deliver.
Even US existing home sales rising to their highest since the 2007 credit crunch or a fifth successive week of declines in oil inventories from the Energy Department’s databank, were able to muster a rally from the bourse.
The market bellwether S&P 500 index was up 0.1% at 2,091, with Newfield Exploration Co (NYSE:NFX) the top riser of 5% to $42.93.
The S&P Midcap 400 was less fortunate, falling 0.05% to 1,493, with Adv Micro Devices (NYSE:AMD) the main faller of 7.3% to $5.05, while the S&P Smallcap 600 shed 0.3% to 705, with Emergent BioSolutions(NYSE:EBS) the main loser of 20.6% to $31.21.
The US oil benchmark West Texas Intermediate was down 2.5% at $48.61
With the polls neck-and-neck on the last day of campaigning ahead of polling on June 23, the European Commission President Jean-Claude Juncker offered a hardline and frank assessment of any victory for the Leave camp: “Out is out,” he said.
Such a vote would be final and not trigger any further renegotiation over the UK’s place in the European Union.
In language which seemed to defy a process of people power, Juncker in an interview with Germany’s Frankfurter Allgemeine Zeitung said he was “basically not a big fan of referendums”.
US investors were also counting what the cost could be of any vote to quit the EU. Britain’s benchmark FTSE 100 index could fall to its lowest point since 2011, slipping below the 5000 mark if the country votes to leave the EU, according to UBS.
That would undoubtedly have a knock-on effect on US market trading.
One of the sharpest fallers was Adobe Systems Inc (NASDAQ:ADBE). After hours on Tuesday it presented a downbeat trading outlook. Adobe stock was down 5.5% at $94.32.
