Patience pays.

What it means

A LEGO set's price curve has a predictable shape. Active retail → retirement announcement → 6-12 month plateau (sometimes a dip as retailers liquidate) → 2-3 year climb to 2-3x MSRP → long tail at premium for rare/iconic sets. The maturation window is the sweet spot.

Why it matters

Most failed LEGO investors aren't wrong about the picks — they're wrong about the timeline. They want a 6-month return on a 3-year asset. The doctrine sets the clock correctly so the strategy can actually work.

In practice

• Buy near retirement, store, set a 24-month minimum hold reminder, revisit at 30 months for exit.
• Use the Portfolio Tracker's 'target exit date' field — not just target price.
• Don't check eBay daily. Once a quarter is enough until the alert fires.

Examples

• LEGO 75192 UCS Millennium Falcon — retired 2024, MSRP $850. Expected exit window: 2026-2027 at $1,800-$2,400 secondary.
• LEGO 71043 Hogwarts Castle — retired 2023, MSRP $500. Currently trading at $700-$900 (early in maturation).
