2026 Q2

SPY was reported at 12.33% of portfolio in the most recent visible filing.

High-water mark
Peak Conviction
88.24% in 2024 Q4

Peak weight helps separate a token disclosure from a real conviction holding the fund genuinely cared about.

Time in book
Holding Window
2024 Q1 to 2026 Q2

Longer holding windows often tell a very different story from short-lived tactical trades or one-quarter experiments.

Decision context
Why It Matters
Position size beats headlines
