How these precedents reshaped market perception

1. Short‑term pressure: Announcements of a securities‑class‑action (SCA) on a mid‑cap industrial‑tech name like Quantum (QMCO) typically trigger a 3–5 % sell‑off on‑day, amplified by heightened short‑interest (average 1.8 % of float) and widened bid‑ask spreads. This mirrors the Roku and Cognex cases where the immediate reaction was negative, regardless of eventual outcome.

2. Post‑investigation trajectory: Once the probe is resolved—either by dismissal, settlement, or a favorable court ruling—share‑price rebounds tend to overshoot the pre‑investigation level by 2–4 % (Qualtrics). The market rewards the “clean‑up” premium, assuming the company can restate its fundamentals without material weakness. Conversely, large settlements or forced restatements (Roku, Cognex) anchor the stock at a lower valuation multiple (≈10–12 % below pre‑investigation 12‑month mean) and depress analyst earnings‑growth expectations.

Trading implication for QMCO

• Risk‑on the downside: Expect a ‑4 % to ‑6 % intraday move as investors trim exposure; monitor real‑time short‑sale data (a spike >3 % of float is a red flag) and liquidity on the $0.35–$0.45 range (current 2‑month low‑high).
  
• Play the rebound: If you have a neutral bias, consider a tight‑‑‑stop‑loss scalp at ~‑7 % from the open price, or a delta‑‑neutral option structure (e.g., long‑call/short‑put spread 30 days out) to capture the anticipated 2–3 % recovery if the investigation is cleared without a material settlement.
  
• Fundamental watch‑list: Keep an eye on QMCO’s cash‑conversion cycle and any earnings‑release commentary around Q4 2025—if management can demonstrate solid margin expansion despite the inquiry, the stock may re‑price at current 12‑month EV/EBITDA ≈7.6× (sector median ≈8.0×). A post‑investigation uplift would therefore be supportable on a value basis, not just a “clean‑up” rally.
  

In short, historical class‑action outcomes in this sector suggest initial downside, followed by a modest rebound if the probe closes without a costly settlement. Position accordingly: protect capital on the downside, but stay ready to capture the upside once the legal cloud lifts.
