Investment Methodology
How DYOR HQ scores, rates, and evaluates investment opportunities
What is a Conviction Score?
The conviction score is a composite 0-100 signal measuring the strength of the risk-adjusted return case over a 12-month investment horizon. It is not a probability of success, nor a target return — it is the overall quality and completeness of the investment case.
The score synthesises three distinct input dimensions:
The Three Pillars
Fundamentals
- Revenue and earnings trajectory
- Competitive position and moat
- Balance sheet quality
- Management quality and capital allocation
- Cash generation and margin structure
Catalysts
- Proximity of upcoming events
- Magnitude of potential re-rating
- Binary vs gradual outcomes
- Regulatory or clinical milestones
- Partnership or M&A potential
Sentiment
- AI-powered news and social media analysis
- Analyst consensus and price targets
- Price momentum and positioning
- Insider activity signals
- Sector and macro tailwinds
Recommendation Tiers
Each report carries two labels: a conviction score (0-100) and a recommendation tier. The tiers translate the raw score into actionable guidance, accounting for stock type and risk profile.
| Score | Recommendation | Position sizing | Description |
|---|---|---|---|
| 80 — 100 | BUY | Full position | Exceptional case. Multiple clear catalysts, strong fundamentals, sentiment turning positive. The highest-conviction opportunities. |
| 65 — 79 | BUY (strong) | Full position | Strong case. Fundamentals are sound, at least one meaningful near-term catalyst. Full position sizing appropriate. |
| 50 — 64 | OPPORTUNISTIC BUY | Half position | Valid case with unresolved risks. Catalysts are either distant or binary. Requires active monitoring and a specific trigger to upgrade. |
| 30 — 49 | SPECULATIVE BUY | Trail-size only | A specific binary catalyst is required to justify the position. For clinical-stage biotech, pre-revenue tech, or turnaround situations where the bull case is low-probability but high-impact. |
| 0 — 29 | Avoid | No position | The investment thesis is broken, the risk/reward is genuinely negative, or the company faces an existential challenge without a credible recovery path. |
In Practice
Examples from current coverage
How the Score is Calculated
Each report uses a bull/base/bear scenario framework:
- Bull case (positive outcome): Assigned a score of 80-120 depending on magnitude
- Base case (central outcome): Assigned a score of 50-70
- Bear case (adverse outcome): Assigned a score of 10-40
Each scenario is weighted (e.g. 30% bull, 55% base, 15% bear) and the weighted sum produces a raw conviction figure, which is normalised to the 0-100 scale. The final score also incorporates the AI sentiment dimension as a market-read adjustment.
The grok sentiment score (0-100) is derived from AI-powered analysis of news and social media. It is treated as one input among three — not a definitive signal on its own. A very low grok score against strong fundamentals (as with ServiceNow in April 2026) may indicate market fear rather than fundamental deterioration, and the score is adjusted accordingly.
Important Caveats
- Not financial advice: All research is for informational purposes only. DYOR HQ research does not constitute financial advice. Always conduct your own due diligence.
- Past performance: Historical conviction scores and recommendations do not predict future outcomes. Markets are forward-looking and conditions change.
- Binary events: Clinical-stage biotech, early-stage tech, and turnaround situations carry binary risk that no scoring framework fully captures. Position sizing should reflect the true probability-weighted outcome, not just the conviction score.
- Sentiment limitations: AI-powered sentiment analysis reflects current market mood, not fundamental value. During market dislocations, sentiment can detach from fundamentals for extended periods.
- Currency: All prices and market cap figures use the native currency of the primary exchange. GBX (pence) stocks are denoted with .L ticker suffix. USD stocks use the plain ticker.
