What this view can't show you

  • 45-day disclosure lag: positions are reported up to 45 days after each quarter ends; the manager may have rotated by the time you see them.
  • Long-only disclosure: short positions are not reported. Puts are shown at notional, not the premium paid.
  • Options excluded from the % line: the performance line tracks the disclosed stock holdings only; puts and calls are left out. Long calls still count toward the portfolio-value figure and the allocation donut; put notional is excluded from both.
  • Disclosed value ≠ performance: growth in disclosed value reflects market moves, new investor capital, and new buys; it is not pure returns.
  • Index caps each position at 30%: the performance line holds no single name above 30% (the rest as cash), so one outsized pick can’t dominate the return. The allocation donut shows the true disclosed weight, which may be higher.
