How is the HeartGold Collection · Composite calculated?
The level is the constituents' combined market cap (fair value times graded population) divided by a divisor, with each card's weight dampened by the confidence of its fair value. The index rebalances weekly and the divisor absorbs every membership and population change, so only prices move the level. Values are recomputed daily from graded sales.
