Market cap ~$600K, ~606K shares outstanding, near-zero revenue, heavy losses, and multiple 2026 reverse splits to stay listed. Classic thin-float momentum name.

Action: Through the trigger while RVOL stays elevated (3+).
Invalidation: Lose the PDH on fading volume.
Size: Small. Whole shares only.

Key Levels

• Critical support / PDH: $0.86–$0.90

Invalidation / Fade

Trigger

Condition

Declining volume

Outcome

High failure risk

Scanner explicitly flags this. Common outcome when the volume spike collapses.

Example size (aggressive): Entry $1.02, stop $0.85 → ~$0.17 risk per share (~16.7%). 14 shares ≈ $14.28 cost / ~$2.38 risk. To $1.35 ≈ 32% gain (R:R ~1.9:1). To $1.75 ≈ 72% gain (R:R ~4.3:1).

Probability & Risk Context

• Short-term: 72/100 scanner score is consistent with high-RVOL ignition on thin float. Continuation possible for 1–3 sessions if volume holds and PDH is defended. Many fail the same day or next session.
• Longer-term: Fundamentals do not support the price. Reverse-split history, dilution risk, cash burn, and regulatory hurdles are real. Extreme volatility is normal.
• Edge: Exists only as a tightly defined, small-size momentum trade with hard invalidation. Oversized or buy-and-hold positions have negative expectancy.
