SK03 · Skyridge Set Index

On Nov 12, 2026 the Skyridge index (SK03) stood at 384.87 (Jan 2022 = 100), and one raw copy of each of the 181 cards it prices cost about $31,206 at eBay sold prices read on PriceCharting. It is re-marked every Monday and Thursday. 100 = Jan 2022, 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: 38 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 ($31,206 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 20.0% 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 81.082208; 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. 1 of 182 cards is in the universe but not the basket — too few clean sales in the trailing 90 days at the last screen: Underground Expedition #140. Left out of the universe on purpose: the four box toppers (Charizard, Crobat, Ho-Oh, Kabutops) — oversized promos sold with the box, not set slots. n30 is a liquidity gate, never a volume figure (the source caps its table at 60 rows). The last WOTC set (2003). The 32 H-numbered holos and the six Crystal cards (#145–#150: Celebi, Charizard, Crobat, Golem, Ho-Oh, Kabutops) are the set's value and are standing constituents under the holo rule; the Crystal Charizard and Gengar H9 sell a few times a quarter raw, so their marks are flagged thin and dated. 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.
