Sonos Shorts Stabilise, but the July Build Lingers

SONO heads into its August 5 earnings print with the frantic short-covering of last week giving way to a more ambiguous setup — shorts have partly refilled, the stock jumped 7.6% on Monday, and options positioning has grown marginally more cautious.

The short interest story has shifted since the previous note. After collapsing 26% in the week to July 29, short interest ticked back up roughly 5% over the two sessions to July 31, landing at 11.7 million shares — 9.7% of the free float. That is still well below the mid-July peak of 15.1 million shares, but the partial rebuild after covering suggests not all shorts have abandoned the thesis. The borrow market remains relaxed throughout this: availability holds at 561%, comfortably in the normal range, and cost-to-borrow is a negligible 0.42%. There is no lending-market pressure forcing anyone's hand here — the covering and rebuilding both look discretionary.

Options have edged slightly more defensive, though not dramatically so. The put/call ratio moved to 0.37, just above its 20-day average of 0.33 — a z-score of about 1.1, modest by any standard. That is a mild shift from the constructive sub-average reading that held through late July, but it falls well short of the defensive hedging posture that would signal genuine alarm. The stock's own trajectory offers context: SONO is up 16% over the past month to $15.77, and that Monday session alone added 7.6%, compressing the gap to the analyst consensus target of $18.88.

The bull-bear debate turns on whether Sonos can sustain the revenue trajectory and margin progress that have re-rated the stock this year. Bulls point to expense discipline, direct-to-consumer momentum, and international expansion headroom. Bears note that the EV/EBITDA multiple has climbed to 8.8x — which, as the bear case itself acknowledges, is not obviously cheap for a consumer discretionary name facing cost pressures and lingering litigation risk around its patent portfolio. The only recent analyst action of note is Rosenblatt reiterating its Buy and $21 target on July 30, leaving the consensus constructive but not freshly upgraded. A prior earnings print in May produced a 6.3% one-day gain; the most recent comparable result, from late July, dropped 14% — a wide dispersion that underscores how binary these prints have been.

Tomorrow's report will test whether the revenue deceleration flagged in prior guidance is shallow enough to justify the stock's 16% monthly run, and whether margin progress has been durable or front-loaded.
