AQ03 · Aquapolis Set Index

On Nov 12, 2026 the Aquapolis index (AQ03) stood at 371.19 (Oct 2021 = 100), and one raw copy of each of the 186 cards it prices cost about $13,466 at eBay sold prices read on PriceCharting. It is re-marked every Monday and Thursday. 100 = Oct 2021, the first month the sold history reliably covers (the set predates it); months before 09/28/26 are reconstructed from monthly price history, live marks since 09/28/26. This block tracks the set; it does not recommend cards.

Method. One set, one index. The universe is every card in the set; the basket is the cards that trade as ungraded singles — at least 6 clean single-card sold comps in the trailing 90 days to enter, 4 to stay. The holo rule: 35 holo-tier cards (holos, Shinings, Crystals, secret and illustration rares — by printed rarity) are standing constituents. They are never screened out, because a set's value sits in its holos and raw holos trade slower than commons precisely because they cost more; all of them currently clear the screen on their own. Price-weighted on PriceCharting's dated ungraded sold list (eBay sales, with TCGplayer sales where PriceCharting records them), never asks. The TCGplayer shop price shown beside each card is a separate number and is not in the level. No caps. The index is the cost of one copy of every card in the basket ($13,466 today), indexed to 100 at the base month: a card's weight is its price over that sum and moves with prices, nothing is ever trimmed, and there is no rebalance — the top card is 18.6% because that is what the set is. (The 25% single-card and 5/50 group caps used Sep 15 – Oct 12, 2026 were retired on Oct 12: a set cannot trim a Charizard the way an ETF trims a position.) Level = Σ(sold mark) ÷ divisor 36.278454; entries and exits are logged divisor adjustments; reconstitution quarterly (first Monday of Jan/Apr/Jul/Oct, announced the Monday before). The plain read's whole-set figure is the plain sum of every priced card's sold mark, one copy each, raw and uncapped, with its window and date printed; its change compares the same cards at two market marks at least five days apart and never across a divisor row. It is what the set costs to buy, not a level. Every card in the universe is in the basket. Left out of the universe on purpose: the four box toppers (Entei, Espeon, Scizor, Suicune) — oversized promos sold with the box, not set slots; two reverse-holo rows (Drowzee #74, Mr. Mime #95) — reverse holos are separate items. n30 is a liquidity gate, never a volume figure (the source caps its table at 60 rows). An e-Card set (2003); the Crystal Lugia #149 leads, with Crystal Nidoking #150 and the 32 H-numbered holos behind it — all standing constituents under the holo rule. Reverse holo prints are separate items and are not in this index. Raw e-Card singles sell a few times a month, so this index screens and marks on 90 days of sales (enter at 6, stay at 4). A raw copy can be any condition, so the mark is the median raw sale, not a near-mint price. Bid buttons are live eBay auctions on the exact card (verified title, soonest close with bids first, refreshed every 15 minutes) — bids, not marks. An index is a measurement, not a call.
