Why This Score

SION scores 31.6 on the Conservative profile, blending a fundamental score (80% weight, emphasizing quality and stability (84% of fundamental weight)) with a machine-learning signal (20% weight) trained on 82 features across 30 years of data.

Strengths
  • Minimal leverage (D/E 0.03) provides financial flexibility and downside protection.
  • ML model assigns a high-conviction signal (98/100), indicating strong pattern recognition across 82 features.
Risk Factors
  • Liquidity concern: Limited trading volume or float results in a 2-point penalty for execution risk.
  • Signal divergence: Fundamental and ML signals disagree by a significant margin, reducing confidence.
  • Above-average volatility (20.0%) may not suit conservative risk tolerance.

Net penalties of -25.4 points significantly impact the ranking. Without these adjustments, SION would rank considerably higher.
