Koss Corporation heads into its May 8 earnings print with short sellers incrementally rebuilding positions — but the borrow market and overall positioning leave no obvious pressure on either side.
Short interest climbed to 2.5% of the free float on May 6, up from roughly 2.1% a week earlier and 17% higher in absolute share count over the past month. That move is worth noting but not alarming: at $4.18, the stock is small and lightly traded, and borrow conditions remain easy. The cost to borrow runs at just 0.82% annualised, with availability at nearly 370% of short interest — meaning lenders hold almost four shares available for every one currently borrowed. Nothing in the lending market suggests squeeze pressure or a crowded short thesis.
The ORTEX short score of 47.7 sits roughly in the middle of its range — it touched a recent high of 49.5 in late April before easing, then crept back up on May 6. Days to cover stands at 7.3 based on official FINRA data, which reflects the thin liquidity typical of a micro-cap with a $41 million market cap rather than any acute short-side conviction.
The ownership story underscores how tightly held this company is. The Koss family and associated trusts control well over 40% of shares outstanding. Institutional presence is thin — Vanguard and BlackRock hold combined stakes under 3.3%, while the top 25 institutional holders together account for a modest slice of the float. The most recent insider activity on record was a small director purchase of 2,500 shares in December 2025, worth $12,400. Family VP sales from mid-2025 total a few hundred thousand dollars across several tranches — directionally consistent with insiders lightly trimming over time, but nothing that reads as a signal ahead of this specific print.
The stock has pulled back 2.7% in the past session and 3.4% on the week, paring a 10% gain over the prior month. Historically, Koss has tended to drift lower following results: the last four earnings events each produced a negative one-day reaction, ranging from -0.5% to -3.4%, with five-day moves mostly extending those losses — the clearest exception being a brief January 2026 bounce that faded quickly. The earnings report will test whether the stock's one-month rally into the print reflects genuine fundamental improvement or simply reverts to that familiar post-earnings pattern.
