A fund publishes only its largest positions, so this measurement reaches 44% of the money. The share above is what is shared within that part: it is a floor, never the total overlap.

The worst falls on record

Holding	Worst fall	Volatility

What this does not say

Every figure is measured on past daily prices over the window below. It is not a forecast of returns or losses.
The window starts when the younger fund began trading, so older crises may lie outside it.
The overlap is measured through published holdings only, and is a floor: the real figure is at least this, and cannot be smaller.
Which of two funds to hold depends on things not measured here — what you already own, costs at your broker, and your own tax position.
