Consistent trading in S&P 500 variance futures has been seen over the last few weeks, as investors look to play the spread between realized and implied volatility.

Rob Hocking, global head of equity volatility trading at DRW, noted 50 day realized vol at the close on Wednesday in the S&P was roughly 6.6%, with the July S&P var future settling at 12.25%. “So that represents a spread of roughly 5.5 vols,” he said. “People are trying to use the products that can capture that as an overlay strategy to their vol portfolios, because vols are extraordinarily low right now, but the spread between realized and implied is also fairly large. People are looking at ways to capture that.” DRW is the primary market maker on the S&P var futures.

The future was first launched in December 2012, but it has struggled to attract market interest in large part because the margin requirements for trading the product compare unfavorably with the same requirements for trading its over-the-counter swap counterpart. Changes to initial margin rules, which came into force last October, were tipped to spur activity in the contract. 

According to date gleaned from the TradeRivet twitter feed, which provides the methodology for the contracts, the activity seen over the last few weeks has consisted of varying vega. The first spate of contracts traded from April 10-to-April 12, totaling 8,000 vega. Further trading was seen on May 3 with 10,000 vega June contracts executing, while a further 6000 June vega was seen on Thursday. While 1000 vega represents “one lot” on the listed markets, the typical OTC size is 50,000 vega.
