This token is a claim on BTech Holdings Limited, not a share of ProShares UltraPro Short QQQ. The wrapper, voting and redemption terms below are what you actually hold.
The contract address is not in the upstream payload, so it shows a dash and links out rather than being guessed.
"Since listing" rather than "all-time": this token began on 2026-09-01, so its extremes say nothing about ProShares UltraPro Short QQQ's own history. No premium or discount is shown — a token is not one share, and the multiple is not constant even within one issuer.
