HoldLens
Methodology

How we calculate everything

Data sources

Every position on HoldLens comes from SEC EDGAR 13F filings — quarterly disclosures required from any institutional investment manager with over $100M in assets under management. We supplement with Form 4 (insider trades) and Form 13G/13D (large position disclosures).

  • 13F-HR: Long US equity positions, filed within 45 days of quarter end
  • Form 4: Insider buys + sells, filed within 2 business days
  • 13G/13D: Large position changes (5%+), filed in real time

The 45-day lag (and why it matters)

13F filings are due 45 days after each quarter ends. Translation: when you see a position on HoldLens, the actual buy/sell happened 6 weeks to 4 months ago. We never pretend otherwise. HoldLens is for pattern recognition, not copy-trading.

Conviction Score (coming v0.4)

A position is high-conviction when it's: (a) large relative to the manager's typical position size, (b) added to over multiple quarters, (c) held even after price drawdowns. Our Conviction Score combines all three signals into a single 0-100 number per position.

Consensus Score (coming v0.4)

When 5+ tracked managers independently buy the same stock in the same quarter, that's a consensus signal. Our Consensus Score weighs the manager's track record + position size to flag emerging themes one quarter early.

What we don't show

  • ❌ Short positions (not in 13Fs)
  • ❌ Options exposure (notional only, no detail)
  • ❌ Non-US equities (not in 13Fs)
  • ❌ Bonds, crypto, real estate (not in 13Fs)
  • ❌ Real-time positions (legal floor: 45 days)

If you need real-time, options-aware data, you need a Bloomberg terminal — or more accurately, you need to be at one of these funds. HoldLens is the best public data made beautiful.

Updates

Manager portfolios update within hours of each 13F filing. Email subscribers get a one-line move alert per filing. We never delete historical data — every quarter is preserved.
