Informational only — not investment advice. HoldLens tracks institutional positioning from public 13F filings. We are not a registered investment advisor and do not provide recommendations to buy or sell securities. Our 2026 backtest over 221 ticker-quarter pairs found the ConvictionScore has no predictive signal for forward returns (Pearson r = −0.12). The rankings describe what tracked superinvestors were accumulating or selling at the latest 13F snapshot — useful as market intelligence, not as personal investment advice. 13F data is reported with a 45-day SEC filing lag.

See the 9 factors that produced −8 for LBTYK

HoldLens's ConvictionScore is the sum of 9 factors clamped to −100/+100. Each factor has a known min/max range; the math is deterministic and reproducible. Every input traces to a public SEC filing. Full methodology →

Factor	Contribution	Range	What it measures
Smart money	+2	0 to +30	Sum of buyer manager quality × consensus (number of managers buying weighted by track record).
Insider activity	0	-15 to +20	Form 4 CEO/CFO/director discretionary buys (+) or sells (−) in last 90 days.
Track record	-8	-10 to +20	Buyer's 10-year compound annual return × position concentration. Pros placing big bets count more.
Trend streak	0	0 to +10	Multi-quarter compounding — managers adding for 3+ consecutive quarters.
Concentration	+2	0 to +10	Biggest position size among buyers — proves conviction.
Contrarian bonus	0	0 to +10	Under-the-radar — fewer total managers know about it = more upside if right.
8-K events	0	-15 to +5	Material events filed last 90 days — Chapter 11 (−), CEO change, M&A, etc.
Dissent	+5	-40 to +0	Sellers subtract from the buy signal — weighted ×1.6 relative to buys.
Crowding	0	-10 to +0	Too many managers holding = price already reflects consensus = less upside.
Sum (clamped −100/+100)	−8	−100 to +100	(raw sum 1 clamped to score -8)

How to read: emerald = positive contribution to the buy signal; rose = penalty (sellers, crowded ownership, bearish 8-K events). Hover any factor name in the methodology page for the exact formula. Every number is computed at build time from EDGAR filings — no proprietary opinion layer, no editorial scoring. For LBTYK specifically: 9 buyers vs 11 sellers among the 30 tracked managers.
