Dr Richard Evans, Darden School of Business

While ETFs constitute just under 10 per cent of US equity market capitalisation, they account for over 20 per cent of short interest and over 78 per cent of failures-to-deliver in US equities. While the disproportionate share of short activity in ETFs has raised concerns about excessive shorting and naked short-selling, we identify an alternative cause for this activity related to the market making activities associated with the ETF creation/redemption process, which we label “operational shorting”. We propose a simple methodology to estimate operational shorting and show that our measure is consistent with the economics behind the mechanism. In examining the market implications of operational shorting, we find that it is associated with improved liquidity but that it is also predictive of market-wide indicators of systemic and counterparty risk. In exploring possible mechanisms for this predictive relation, we find there is commonality in operational shorting across ETFs that have the same lead market maker/authorised participant and that market makers’ financial leverage might be a channel that amplifies this commonality, both of which are suggestive of an increase in counterparty risk.
