Koss Corporation (KOSS) Insider, 13F Hedge Fund & Politician Buy/Sell Thermometer

Per the Roarable RQD rating, KOSS scores 27 out of 100, a letter grade of E, labeled "Roarable Strong Sell — Forensic Risk / Avoid." The five pillars are: Fundamental Cash Engine at 7/20 (ROIC -4.9%; FCF yield -2.19%), Whale 13F Flow at 4/20 (institutional accumulation and options positioning), Insider Conviction at 3/20 (SEC Form 4 and Congressional PTR cluster flow), Macro Regime Fit at 3/20 (Beta 1.0; sector sensitivity), and Forensic Balance Sheet at 10/20 (Altman Z 4.47; Piotroski F 4/9; Debt/Equity 0.5).

The weakest pillars are insider conviction, macro regime fit, and whale flow, each at or below 4 of 20. The strongest pillar, forensic balance sheet, is still only half-credited, and it is the pillar with the most mixed signal: a relatively high Altman Z-Score alongside a middling Piotroski F-Score of 4 out of 9. For a prospective investor, the upside case rests on the balance sheet holding up and on the stock trading near the lower end of its range, but the cash engine is negative on both ROIC and FCF yield, so the valuation case is not supported by current cash generation. The rating does not make a valuation judgment on its own; it flags that the available evidence leans negative across most dimensions.
