Symbol facts and market observations

About this symbol

The index is made up of 100 non-financial companies listed on U.S. exchanges. Weights are set by modified market capitalization. During the cash session the spot index value is used directly.

Sources: trade[XYZ] (contract issuer), trade[XYZ] (contract issuer).

Its after-hours reference futures are quarterly contracts that rotate in the order H6, M6, U6, and Z6. The equity-index oracle method moved to v2 on 19 February 2026, while XYZ100 began on v1. Under v1, the discount rate was fixed at 4% and prices came from Pyth's U.S. equity-index feed. The perpetual futures contract allows maximum leverage of 30 times, a price band of 3.5% above or below the reference, and cross margin. The funding rate applies a factor of 0.5 to Hyperliquid's formula, and the API also records 0.5. All of the above is from trade[XYZ], Hyperliquid, and the cited API responses.

Frequently asked questions

Is this number the index itself?

It is not the index value itself. It is a reference value for a perpetual futures contract on the index. During the hours when the cash index is calculated, the contract references that index value. Outside those hours, it derives an index-equivalent value from index futures quotes.

Why does it move while the local market is closed?

Outside the hours when the cash index is calculated, an index-equivalent value is derived from index futures quotes. The calculation hours for each index are stated in “About this symbol.”

Who produces the index?

“About this symbol” identifies the organization that calculates and publishes the index. It is shown only for symbols where that information has been retrieved.

Is a list of index constituents available?

No. Constituents can change. “About this symbol” states only the rules and timing for constituent changes.
