MUSQ, the Global Music Industry Index ETF, closes this week with a quiet but telling divergence: short sellers have been cutting positions sharply while the cost of borrowing stock has crept back up.
The short interest story is one of steady retreat. Estimated short interest has fallen 37% over the past month, from roughly 355 shares in mid-April to around 154 shares now. That is a tiny absolute number for any ETF — short interest amounts to less than 0.02% of the float, making it essentially negligible as a directional signal. The week itself saw a 10% decline in shares short, even after a one-day blip higher on May 12. With positions this small, the shorts are a rounding error rather than a structural bet against the fund.
The lending market tells a slightly more interesting story. Availability is wide open — the borrow pool is far from stressed. Yet the cost to borrow has climbed back to 10.37% annualised, up about 3% on the week, after falling roughly 21% over the prior month. That puts borrowing costs at roughly mid-range for the past year; the peak was close to 18% last September, and the trough was around 5-6% in late 2025. The recent uptick in cost, even as short interest fell, suggests a tightening in the supply of available stock rather than new short-selling demand — an ETF-specific dynamic where creation/redemption mechanics can move the borrow market independently of sentiment.
Price performance has been unremarkable but positive. MUSQ gained roughly 0.8% on the week and is up 2% over the past month, closing at $25.70 on Tuesday. The ORTEX short score edged up to 34.6 from about 32.5 a week ago — a modest move that reflects the one-day spike in estimated short shares. At current levels the score remains well below any threshold that would flag meaningful short-side pressure.
With no earnings catalyst, no analyst coverage in the data, and minimal short interest, the main variable worth watching is whether the cost to borrow continues its quiet drift higher — and whether that reflects a broader tightening in ETF lending supply across music and media-adjacent names.
