Overall Fixed Income ETF short exposure decreased from $33.4 billion to $33.3 billion, a decrease of $2.1 billion, or -6.2%, over the last 30 days. Change in short interest consists of mark-to-market price changes of existing shorts and short selling and covering. Over the last 30 days we saw a $993 million decrease in the market-to-market value of existing short positions which was joined by $1.08 billion new net short covering.
As the value of their assets declined, a profitable market move for the short-side, ETF short sellers bought to cover and reduced their overall ETF exposure. This indicates that ETF short sellers were looking to decrease their exposure as the markets declined, either decreasing their outstanding portfolio hedges or reducing short-side risk (Alpha generating) positions.
On the short-selling side the ETF with the largest amount of new short selling was the Vanguard Short-Term Bond ETF (BSV).
On the short-covering side we saw the largest activity in three of the four largest Fixed Income ETFs, the iShares iBoxx $ High Yield Corp Bond ETF (HYG), the iShares 20+ Treasury Bond ETF (TLT) and Spider Bloomberg High Yield Bond ETF (JNK). The one Fixed Income ETF of the top four most shorted with increased short selling over the last thirty days was the iShares iBoxx $ Investment Grade Corporate Bond ETF (LQD).
Fixed Income ETF short sellers were reducing exposure most of the largest and most liquid ETFs which are the primary portfolio hedging securities used by hedge funds.

ETF stock borrow fees rarely get very expensive (over 5% fee) as brokers will usually create ETF shares in order to meet stock borrow demand as rates make the share creation and hedging profitable. Rates in certain ETFs tend to climb for two main reasons, there is very little marginable or rehypothicatable stock in the market which limits the stock lending availability pool or the process of creating and hedging the ETF is difficult or very expensive (active ETFs or ETF with illiquid constituents). The following are ETFs with the highest stock borrow fees with short interest over $5 million.

Institutionally, ETFs are primarily used as a portfolio hedging vehicles (shorts in the HYG, LQD, JNK and TLT ETFs make up 55% of total Fixed Income ETF short interest) so one can expect that in a downward trending market most of the larger ETF short positions would have large positive returns. Since the beginning of March, before the FOMC began increasing the fed funds rate and the 10-year treasury was still under 2%, Fixed Income ETF shorts are up $2.45 billion in net-of financing mark-to-market profits, a +7.46% return in less than three months.
90% of shorted ETF’s shorts (333 out of 372 Fixed Income ETFs with short interest) and 98% of every dollar shorted in Fixed Income ETFs have been profitable from March – May. The Fixed Income ETFs with the largest mark-to-market profits for the month are below.
