ES Roll Volumes Punking Market
With this Thursday's roll from the June to the September contract, the volume in the futures is playing tricks on robots and speculators. As the volume in the on the run June (M) contracts begins disappearing, the volume in the September (U) contracts is picking up (although in the chart below the cumulative divergence is pretty much meaningless as there has barely been any volume in this contract prior to today). As such, a big factor for today's late day sell off, which did not occur on any material adverse news, is very likely related to the ES contract roll. If this is the causal factor, look for ongoing roll-related weakness over the next few days. In the meantime, today's weak US close will continue to pressure both Asia, China and Europe overnight, leading to additional spookage in Treasury auctions in Europe, which already has various unrelated liquidity concerns to deal with.
